Abstract
- Superficial acral fibromyxoma (SAF) is an uncommon soft tissue tumor that has recently been showed to be a separate disease entity. It is most often located in the ungal region of the fingers and toes of middle-aged adults. It is histologically characterized by a slight to moderate cellular proliferation of spindle cells and stellate cells arranged in a random, storiform or fascicular pattern, within a myxoid, myxocollagenous or collagenous stroma with a prominent vasculature. The neoplastic cells show positive staining for CD34, CD99 and EMA, but negative staining for S100, HMB45, cytokeratin, smooth muscle actin (SMA) and desmin. We report here on a typical case of SAF that occurred on the left index finger of a 44-year-old man.
