Cellular schwannoma (CS) is a rare, benign, nerve sheath tumor. It is slowly growing and painless, and it shows a predilection for the paravertebral region of the mediastinum and the retroperitoneum. CS rarely occurs in the skin. It has more cellular and more atypical cytological features than ordinary schwannoma but follows a benign clinical course. The key histological feature is a distinct predominance of cellular Antoni A tissue. Herein we report a case of CS presenting as a 5 × 5 × 3 cm, ulcerated and protruding tumor on the left ankle and describe its indolent clinical course.
