AbstractBackground/PurposeThis was a retrospective case series that aimed to study the clinical features and results of surgery for soft tissue chondroma, which is a benign extraskeletal cartilage tumour.MethodsTen patients with a histological diagnosis of soft tissue chondroma were recruited between 2001 and 2012. Tumours involved the hand and wrist (n = 4), foot (n = 3), popliteal fossa (n = 2), and deltoid (n = 1).ResultsThe most common complaints were progressive enlargement of the size of the mass (50%) and pain (50%). Radiographs showed calcified soft tissue mass in 90% of cases. Marginal excision was performed. The mean follow-up duration was 27.6 months. There was one suspected recurrence case with a mass over the index finger. Surgical re-excision was performed and the second histological diagnosis was bizarre parosteal osteochondromatous proliferation. At final follow-up, nine out of ten cases were symptom free. One patient had residual finger joint stiffness and deformity.ConclusionThe results of marginal excisions for soft tissue chondroma is satisfactory with low complication and recurrence rates
