Chondrosarcoma of small bones of the hand.
A clinicopathological review of 23 patients (mean age, 67 years; range, 42-85 years) with chondrosarcoma of the bones of the hand was done. The mean follow up was 8.5 years. Eleven patients presented with a progressive painless swelling, 26% having had symptoms for over 10 years. The proximal phalanx was the commonest site. Initial clinical misdiagnosis as ganglion, bursa, gout, rheumatoid arthritis and a cyst occurred in five patients. Radiologically most lesions showed bone expansion, cortical destruction and soft-tissue extension. The majority was of high histologic grade (Evan's grade 2 & 3) with extensive myxoid areas. Five out of eight patients who were originally treated by curettage or excision had local recurrences compared to none treated by ray resection or amputation of phalanx (P=0.002). None had metastases. The low risk of metastases despite the high histologic grade indicates that chondrosarcomas of the hand behave differently from chondrosarcomas elsewhere.
