Abstract:

A case of superficial acral fibromyxoma is reported. A 43-year-old male patient presented with a 7-year-history progressive mass arising on the left heel. There was no evident discomfort but occasional pain during walking. Clinical examination revealed a plum, solid, well-defined mass sized 1.5 cm × 1.5 cm on the left heel. Histologically, there was a proliferation of numerous spindle or stellate cells arranged in a storiform or fascicular pattern embedded in a myxoid stroma with many small blood vessels; no evident atypia or mitosis was observed in these cells. Immunohistochemical staining of lesional tissue was positive for vimentin, fibronectin, CD34 and early membrane antigen, but negative for smooth muscle antibody, S-100, neurofilaments, desmin or CD99. A diagnosis of superficial acral fibromyxoma was made. The tumor was removed by expanded excision followed by free skin flap transplantation. No recurrence was observed during a 5-month follow up.
