Soft tissue mixed tumor of the hand

Abstract

Mixed tumors are relatively common in the skin and salivary glands, but extremely rare in soft tissues, often resulting in diagnostic problems. The occurrence of these tumors in the hand is especially limited. In this article we report the clinical, radiological, and histological features of a mixed tumor of the hypothenar region of the right hand.

Keywords: hand; immunohistochemistry.; mixed tumor; soft tissue.

(A, B) Photomicrograph of the soft tissue mixed tumor, showing a lobulated architecture with epithelioid cells and myoepithelial elements in the chondromyxoid and collagenous stroma, and evidence of ductal differentiation (H&E stain). Immunohistochemical examination demonstrated positivity for cytokeratin (C) and CD10 (E) in both spindle and epithelioid cells, and S-100 protein in the spindle cells (D).
