Plantar fibromatosis is a relatively rare disease compared to its counterpart in the hand. Though it is considered to be a part of Dupuytrens diathesis it has been less exhaustively studied to enable evidence based management strategies. We followed up all patients presenting with plantar fibromatosis to our institute between 1980 and 2006, identifying 41 patients. 6 patients were lost to followup. Thirty-five patients with 60 involved feet were included in the study. There were 22 males and 13 females, all white Caucasians. The median age at presentation was 45 (19–63 years), and the median follow up was 10 years (2–25 years). Twenty-one of our patients had palmar Dupuytren’s disease, six had knuckle pads, four had Peyronie’s disease, four had other superficial fibomatoses and two keloids. Six were diabetic, four had epilepsy of whom two took valproate and one phenobarbitone. Eight patients had a family history of fibromatoses. The most common presentation was a painful lump (20); 13 patients had a painless lump (13) and two had only pain. All patients reported a proliferative phase of enlarging nodule size, often with pain, which lasted 1–4 years (median 2 years). Thereafter most patients reported improvement in symptoms (size of lump and pain) as well as function. As we came to recognise this, we treated most patients with symptomatic measures and observation only. At review, 17 patients considered their symptoms were improving, 14 were stable and only four had noticed deterioration. Seven patients, mostly early in the series, were treated by wide excision; six had recurrence at review although only one was symptomatic. Plantar fibromatosis is a benign condition which stabilises and may improve after an initial proliferative phase lasting about two years Most patients require no intervention

Introduction: Tumours of the foot are rare, representing only 4 to 8 per cent of all bone and soft tissue tumours: a negligible number compared to degenerative, posttraumatic, vascular and metabolic diseases of this exposed region. Hence neoplasms of the foot are often diagnosed late and treated inadequately. Methods: The records of all tumours of the foot and ankle treated surgically at our institution in the period 1993 to 2007 were reviewed. Because of their non-neoplastic nature typical lesions of the foot such as plantar fibromatosis or Morton neuroma as well as ganglion and the like were not included in this study. History, location, radiographic and clinical findings were analysed, malignant tumours were followed up by X-ray and MRI. Results: Of the eighty-eight cases which were further investigated, there were forty-four bone tumours and forty-four neoplastic soft tissue lesions. Sixty-nine cases (78%) were benign tumours, half of them (35 cases) located in the bone and in the soft tissue (34 cases) respectively. There were forty-four male and female patients each, the mean age being 40 years (range 4 to 85) for all cases, 39 years for benign and 45 years for malign tumours respectively. There were nineteen malignant lesions, nine of which were bone tumours; the most common being chondrosarcoma (3) and osteosarcoma (3). Malignant soft tissue tumours (10) were very heterogeneous, clear cell sarcoma being the only tumour appearing at least twice. Out of thirty-four benign soft tissue tumours, pigmented villonodular synovitis (11), fibrous (9) and lipomatous (5) tumours have been the most frequent. Thirty five benign bone tumours included chondroma (10), solitary bone cyst (10), aneurysmatic bone cyst (3), osteoid-osteoma (3) and giant cell tumour (3). Conclusion: Knowledge of tumour prevalence under consideration of the patient’s age and location of the tumour is an important prerequisite for identifying neoplastic lesions of the foot
