Superficial Acral Fibromyxoma: A Rare Entity - A Case Report.

Superficial acral fibromyxoma (SAF) is a rare lesion initially described by Fetsch as a tumour with histological and immunohistochemical features located at acral sites. It is a benign slow-growing soft tissue lesion occurring in males. Patients generally look for late medical help as it is generally painless. The lesion consists of spindled and stellate-shaped cells in the myxocollagenous stroma with immunohistochemical positivity for CD34, CD99 and vimentin. Treatment is surgical excision with regular follow-up. Here we present a case of a superficial acral fibromyxoma of the left index finger which radiologically showed features of vascular anomaly on MRI. The lesion was surgically excised and histopathology revealed features suggestive of superficial fibromyxoma with positive immunohistochemistry for CD34 and negative for S-100.
