Diagnostic dilemma in soft tissue swelling over finger
Myopericytoma is a benign tumor that shows a pericytic line of differentiation. The lesion is generally located in the dermis and subcutaneous tissue and has a predilection for distal extremities, but may be found in any part of the body. We present a case of 48-year old male who came with painful swelling in right middle finger for the past 2 years. Histopathology showed proliferation of spindle-shaped cells exhibiting a hemangio-pericytomatous pattern with various sized vessels lined by flattened endothelium and surrounded by a concentric arrangement of spindle-shaped cells. Tumor cells show membranous positivity for smooth muscle actin but negative for desmin and CD 34. Hence diagnosis of intravenous myopericytoma was established.
