Introduction

Needle guided biopsy of a suspected musculoskeletal malignancy has become increasingly popular as an effective modality for diagnosis. Biopsy performed in a safe manner should be performed in a centre which is also capable of performing the definitive management of such conditions. Our aim was to determine accuracy and success rates of the image guided biopsies performed by our service.

Methods

A retrospective review of the Bone and Soft Tissue Sarcoma service database was performed to identify all patients who underwent diagnostic biopsy and to identify the results of such investigations. A biopsy was deemed successful if a sample of the target lesion was sampled at the time of biopsy. The successful biopsies were then classified as diagnostic or non-diagnostic if the diagnosis could be reached from the sampled tissue.

Introduction

Bony tumours of foot account for approximately 3% of osseous tumours. However, literature regarding calcaneal tumours comprises individual case reports, short case series or literature reviews, with last large case series in 1973. Literature on bony tumours of the talus is limited to case reports only.

Methods

We retrospectively reviewed medical notes and imaging for all patients with calcaneal or talar tumours recorded in the Scottish Bone Tumour Registry since the 1940's. Demographics, presentation, investigation, histology, management and outcome were reviewed.

Intraosseous schwannoma is a rare benign neoplasm, which most commonly arises in the head and neck region particularly the mandible, due to the long intraosseous path of sensory nerves in the mandible. We present a 27-year-old lady with an unusual presentation of an intraosseous schwannoma of the first metatarsal. There is only one report published previously of an intraossous schwannoma of the lesser metatarsal bone of the foot.

A 27-year-old woman presented with painful left forefoot following a trip while walking. Plain radiographs demonstrated a pathological fracture through a lytic lesion of the first metatarsal of the left foot. MRI scan using axial T1-weighted spin echo and axial and sagittal T2-weighted gradient echo showed an amorphous mass occupying the medulla of the bone but with a breach of the plantar aspect of cortex with apparent localised destruction. Ultrasound-guided biopsy was performed. Haematoxylin and Eosin stained specimen sections showed a proliferation of spindle cells of alternating hypercellularity and hypocellularity. This case was managed by curettage and grafting with autograft and synthetic bone substitute. At two-year follow-up, the radiographs showed complete graft incorporation and a healed cyst. The patient was clinically asymptomatic with return of full functions. There were no clinico-radiological findings to suggest any recurrence.

Due to rarity and non-specific clinico-radiological features, this case illustrates the necessity of a multi-disciplinary approach with an accurate histological diagnosis in combination with radiological and clinical appearances.

Between 1948 and 2004, we report 34 patients with Ewing’s sarcoma of pelvis accrued from Scottish Bone Tumour Registry, aiming to identify the prognostic factors and the influence of various treatment modalities on outcome. There were 19 male and 15 female patients at a mean age of 19 years (range, 3 to 48 years). The Pain was main presenting symptom in 30, swelling in 12 and restriction of hip movements in 11 patients. The commonest anatomical site was ilium. Local control was achieved by surgery, radiotherapy (n=25), chemotherapy (n=23) or a combination. The survival correlated significantly with chemotherapy protocols in favour of the group that received ifosamide (p< 0.01). Metastases at presentation was the most important factor determining survival (P< 0.01). Among the patients who presented without metastases (n=25), there was no statistically significant difference in survival based on the anatomical location of the tumour, age or sex. The mean time to lung metastases from the date of presentation was 13 months, while bone metastases presented at an average of 20 months. None of the patients with the metastasis or local recurrence survived. There were 5 local and 17 systemic (metastatic) relapses. The mean duration of survival was 13 months.

With advances in imaging, aggressive chemotherapy, surgery and conformal radiotherapy which can deliver high dose of radiation with precision, it is possible to achieve a cure rate of more that 50% in non-metastatic pelvic Ewing’s sarcoma. The results of this study favour a middle-path regime combining all treatment modalities.

This study aimed to analyse clinical, radiological and histological features of 29 cases of pathological fractures of the long bones either presented as or occurred during the course of sarcomatous degeneration in Paget’s disease of bone utilising Scottish Bone Tumour Registry between 1950 to 2000. The mean age was 67.2 (range, 53–81) years with 16 males and 13 females. The commonest bone affected was the femur (n=13) followed by humeral (n=8), tibial (n=5), ilium (n=2) and os calcis (n=1) fracture. The mean duration of symptoms prior to presentation was two months. Fourteen patients presented with pain associated with a pathological fracture. One patient presented with painless lump and eleven with painful swelling followed by a pathological fracture. In the remaining three, the patients reported with a delayed or non-union of the pathological fracture. Nine patients presented acutely as pathological fracture being their main presenting symptom. The typical radiological appearance was a lytic (n=22). Histology showed predominantly osteosarcoma (n=17) followed by malignant fibrous histiocytoma (n=7) and pleomorphic sarcoma (n=5). Amputation was carried out in 16, internal fixation in 5 and replacement arthroplasty in two (1-cemented bipolar and 1-Charnley’s total hip arthroplasty). In addition, adjuvant radiotherapy in 13, adjuvant chemotherapy in 3 and combined radiotherapy-chemotherapy in 2 patients was instituted. The mean survival was 19.3 months (humeral=4.6, pelvifemoral=30, tibiocalcaneal=23.3 months). In conclusion, the majority of the pathological fractures in Paget’s sarcoma behave differently from their counterparts (non-Pagetic pathological fractures) with regard to their limb ablation treatment rather than stabilisation operation. The actual occurrence of a pathological fracture did not show to significantly affect the overall survivorship.

Between 1944 to 2003, eighty nine cases were registered with a diagnosis of Paget’s sarcoma in the Scottish Bone and Soft Tissue Tumour Registry. We found thirteen cases of sarcomatous degeneration of the spine (0.26% of the total bone tumour registry case) which were analysed in this study elaborating clinical, radiological and histopathological features. The mean age was 66.9 years (range 56 to 79 years). There were ten males and three females. There were seven cases involving sacral spine (63.6%), three cases involving lumbar vertebrae and two affecting dorsal spine. One case had diffuse dorso-lumbar involvement from D11 to L3 vertebrae. The mode of presentation was increasing low back pain (in all 13), unilateral sciatica (6, left sided-5, right sided-1), bilateral sciatica (2), lower limb weakness (8) and autonomic dysfunction (4, presented as chronic cauda equina syndrome). The majority of the cases (69.23%) were osteosarcomas. Out of these osteosarcomas, two showed giant cell rich matrix and one revealed predominant telengiectatic areas. Rest of the histological types was shared by chondrosarcoma, fibrosarcoma and malignant fibrous histiocytoma. Decompression laminectomy was performed in three cases. Eight patients had received radiotherapy. The mean survival was 3.93 months (range, 1 week to 7 months), nearly half to the whole Scottish Paget’s sarcoma series with a mean survival of 7.5 months. We found a constellation of symptomatology due to radiculo-medullary compression with a fatal evolution, predominantly lumbosacral involvement, predominantly osteosarcomatous histopathology with a poorest prognosis of all Paget’s sarcoma. Although, decompression laminectomy and adjuvant radiotherapy provided reasonable pain relief and palliation; however, there was no significant influence on the overall prognosis of the patients with Paget’s sarcoma of spine in the last six decades.

Ten cases of histologically proven chondromyxoid fibroma (CMF) of the Foot and Ankle with a mean follow-up of 6.1 years were reviewed. The mean age was 19 years (12.8 for skeletally immature and 25.2 for remaining skeletally mature patients). There were 6 males and 4 females. There were 5 phalangeal (3-proximal, 1-middle and 1-terminal phalanx), 3 metatarsal, 1 tarsal affecting body of os calcis and one case of distal tibial involvement. The mean delay in presentation was 16.7 months. The common modes of presentation were pain only (n=4), painful lump (n=4) and painless lump (n=2). Typical x-ray finding was an expansile, lobulated, cystic metaphyeal lesion. Cortical erosion was documented in 50% patients. Histology confirmed by several pathologists due to difficulty in diagnosis. There were two atypical CMF. In four cases, curettage alone was carried out, while 5 underwent curettage along with autogenous bone grafting. One case of distal phalangeal CMF had primary toe amputation. Postoperatively, calcaneal CMF had infection (treated with wound debridement and re-curettage). Two cases observed recurrences after 9 and 16 months from their initial operation. Both of them were male, had preliminary proximal phalangeal CMF, showed to have cortical erosion and were treated with curettage only. Re-curettage was done for one, while toe amputation through the metatarsal neck was performed for another recurrence. Foot phalangeal CMF which were initially treated with curettage only should be kept under close follow-up as we observed 20% recurrence rate within two year period. Cases with cortical erosion should be supplemented with autogenous bone grafting.

A 68 year old lady presented with one year history of painful right heel. She noticed slowly growing swelling resulting in broadening of the heel and difficulty in putting on her shoe-wear for a period of two months. On physical examination, there was a diffuse swelling over the posterior aspect of the right heel. The mass was firm to hard, mildly tender on palpation, fixed to bone and deep-seated. There was no erythema with increased warmth over the area of the mass. Plain x-ray of the affected heel revealed a pathological avulsion fracture of the posterosuperior corner of the calcaneus with typical Pagetoid features in the form of diffuse cortical thickening, coarsened trabeculae, loss of corticotrabecular differentiation and poorly demarcated osteolytic destruction. The lateral radiograph of the left heel showed normal radiological appearance of the os calcis. Chest x-ray was normal. The histological examination showed malignant fibrous histiocytoma characterised by the abundance of pleomorphic cells, spindle cells, lipid containing macrophages and touton type giant cells. The microvascular invasion and amount of mitosis declared the tumour as a high grade anaplastic, pleomorphic tumour. A below knee amputation was done approximately 3 weeks from the date of biopsy and after full staging. The patient died after surviving for a period of 6 years and 8 months from the date of biopsy. It is important to recognise the fact that an avulsion fracture can be pathological in nature and secondary to Paget’s sarcoma in patients with Paget’s disease. This case highlights that a high index of suspicion should be observed in patients presenting with a chronic heel pain who are shown to have pre-existing Paget’s disease on radiological grounds and who may have an avulsion fracture or other localising signs of underlying sarcomatous degeneration.

Introduction: Lumps of the foot present relatively infrequently to the orthopaedic service. There have been very few published studies looking at the differential diagnosis of such lesions and there is no clear evidence for the prevalence of malignant lesions in patients presenting with foot lumps.

Aim: To assess the prevalence of malignant lesions identified in patients presenting with a lump on the foot.

Methods: All patients presenting to a regional centre with a foot lump who required surgical excision of their lesion were identified over a 3 year period. All case notes were retrospectively reviewed. Data recorded included patient demographics, presenting characteristics, pre-operative diagnosis and histological diagnosis The centre includes a tumour service and serves a population of 550,000 patients. Tertiary referrals from out-with the direct catchment area of the centre were excluded.

Results: 101 cases presenting during this study period underwent surgery. Average age was 47.3 years (range 14–79) and there was a significant female preponderance with 73 females and 28 males. There was only one malignant tumour although 32 different histological diagnoses were identified. Only 58 out of the 101 lumps were correctly diagnosed prior to surgery.

Conclusions: We have shown that the prevalence of malignant lesion presenting as foot lumps is low but there are a wide variety of potential diagnoses which have to be considered. Pre-operative diagnosis is often inaccurate, therefore surgical excision and histological diagnosis should still be sought if there is any uncertainty.

We describe a 65 year old gentleman presented with a three month history of painful lump in the right forearm which was subsequently confirmed to be osteosarcomatous degeneration in the Paget’s disease of the radius.

A 65 year old gentleman presented with a three month history of painful lump in the right forearm with overlying redness thought by the patient to be the result of recent sun exposure. On physical examination, there was an 8 x 10 cm sized mass over the radial aspect of the right forearm. The mass was soft to firm, mildly tender to palpation, fixed to bone and deep-seated. There was erythema with increased warmth over the area of the mass. There was significant restriction of forearm supination and pronation. Neurovascular examination was normal. Chest x-ray was normal. Plain x-ray of the affected forearm revealed a mixed pattern (both sclerotic and lytic appearance) affecting the entire diaphyseal portion of the radius with soft tissue extension in the mid-shaft. There were alterations in the trabecular pattern of the bone, thickened cortices, encroachment of the medullary space and an increase in the size and deformity of the entire length of the radius with cortical destruction sparing the ulna. Bone scan showed multiple hot foci with an increase uptake in the sacrum, left hemipelvis, L3 vertebra and intensely increased uptake over the right radius. On the 10th day of presentation, an open incisional biopsy was done. Microscopy showed a high grade sarcomatous tumour with areas of osteoid formation. There was evidence of vascular invasion. The presence of preexisting Paget’s disease of bone was confirmed in the specimen. An above elbow amputation was done 4 weeks from the date of biopsy and after full staging. The patient died 16 months with multiple metastases from the date of diagnosis.

Any patient with Paget’s disease who develops new pain in a previously pain-free area of Paget’s disease, or worsening of pain, or a painful progressive mass or a lytic area in sclerotic Paget’s bone should be evaluated for possible sarcomatous degeneration.

Between 1944 to 2003, ninety cases of Paget’s sarcoma from the Scottish Bone and Soft Tissue Tumour Registry were reviewed. The mean age of patients was 72.3 years (range, 30 to 85 years). There were 59 males and 30 females. The most frequent sites were the femur (26), pelvis (19), humerus (13), tibia (11), and thoraco-lumbosacral spine (9). Biopsy was done in 69 cases. In the remainder 20 cases, the histological diagnosis was confirmed either from examining amputated limb or at autopsy. The most common type was osteosarcoma. Local excision was performed in seven cases. Resection in two cases and prosthetic replacement in two cases was carried out. Twenty nine patients underwent amputation surgery. Chemotherapy was administered to 15 patients (including 2 preop chemotherapy). Fifty one patients received radiotherapy (preoperatively in eight patients). All the patients died within one year from the date of biopsy with an average survival time of 7.5 months. Patients with Paget’s sarcoma tend to have a very poor prognosis inspite of improvements in therapy strategies including surgery, radiation therapy, and chemotherapy. We emphasise the need for more research by a combined oncosurgical, oncological, radiological and histological approach in the management of Paget sarcoma to improve the prognosis.

Fourteen cases of pigmented villonodular synovitis (PVNS) of the foot and ankle (between January 1957 and December 1999) accrued from Scottish bone tumor registry are presented with an average follow-up of 4.6 years aimed to analyse the clinical, radiological and histopathological features in order to investigate the clinical behaviour of PVNS in the foot and ankle, and to determine the factors influencing recurrence. The mean age was 26.4 years (range, 8 to 52 years). There were eight females and six males. The mean delay in presentation was 10.3 months. The anatomical sites were foot phalanges (n=2), tarso-metatarsal area (n=3) and hindfoot (n=9). Hindfoot cases comprised of 6 extra-articular soft tissue swelling around the ankle, two affecting the ankle joint and one involving the subtalar joint. There were eight (57.1%) cases presented with painless lump, five (35.7%) patients with painful lumps and one case with a lump associated with toe deformity. The clinical suspicion were ganglion, gout, soft tissue swelling (? tumour) and exostosis. Peri-articular tissue invasion and cortical infiltration was found in one third on plain films. CT scan showed multiple lytic lesions and MRI scan findings were consistent with extensive low signal soft tissue hypertrophy and bone erosion, two of which were suspected with synovial sarcoma. Excision of the lump was done in 4 cases with a complete recovery. Foot phalangeal PVNS were treated with toe amputation through metatarsophalangeal joint and no cases had recurrence of the lesion. There were two recurrences affecting the ankle and the subtalar joint. Recurrent ankle PVNS was treated with re-exploration, open synovectomy, curettage of talar cyst and autogenous bone grafting. The second recurrent case involving subtalar joint was treated with re-excision and curettage. Both recurred cases were primarily treated with intralesional excision for their diffuse variety. There were no recurrences in the nodular variety. Complete recovery was achieved in 85.7% case (12/14). A high index of suspicion for PVNS should be observed for cases presenting with a painless or painful mass in the foot and ankle region. Complete recovery can be achieved in the majority by complete excision. Toe amputation may be considered for foot phalangeal PVNS.

Aims: To assess the reliability of ultrasound guided (USG) tru-cut needle biopsy technique in the management of soft tissue tumours.

Methods: Pathology reports of patients who underwent USG needle biopsy and surgical resection of the tumour between 1994 and 2002 were reviewed. 141 biopsies (142 patients; 59 females and 82 males; mean age 52.5 years [range 16 to 96]) were included. Exclusions were those who did not undergo both procedures, had recurrent disease, had previous biopsy of same site, inadequate or damaged biopsy materials.

Results: Final histology showed 74 malignant and 68 benign tumours compared with 72 and 70, respectively, on biopsy reports, with 94.6% sensitivity, 97.1% specificity, 97.2% positive predictive value (PPV) and 94.3% negative predictive value (NPV). The histological grade was commented on in 48 cases. Final histology reported 18 high grades versus 30 low or medium grades compared to 17 and 31, respectively, on biopsy reports, giving 88.9% sensitivity, 96.7% specificity, 94.1% PPV and 93.5% NPV. Overall accuracy is 95.8% for malignant/benign reporting and 93.8% for grading. One patient developed superficial haematoma that underwent spontaneous uneventful resolution.

Conclusions: This technique is as reliable as open biopsy, yet avoids the need for general anaesthesia and inpatient admission. Tumour visualisation improves sampling while the larger needle gives greater volume than fine needle aspiration.
