Introduction:Giant cell tumor (GCT) or osteoclastoma is an osteolytic, mostly benign but locally aggressive tumor occurring in young adults at the epiphysis. Area of predilection is mainly long bones (85-90%). 4% of GCT are also found in iliac bone, spine and only 2% in hand (of which GCT phalanges are more common than metacarpal). GCT of metatarsal is a very rare occurrence with very few cases being reported so far. We report a case of GCT 1st metatarsal in a 40-year-old male which is a very rare entity. We shall discuss the clinical features, pathological and radiological hallmarks, and the various treatment modalities of such lesion.
