Ciliated cutaneous cyst of the foot.

We report a 36-year-old woman with a cutaneous cyst of the dorsal aspect of the left foot. Because of the symptoms of pain and paresthesias attributed to the lesion, it was clinically felt to be a ganglion. After excision, these symptoms abated. Yet histologic examination showed this lesion to be a rare tumor, the ciliated cutaneous cyst. This is the third patient with this distinctive lesion on the foot or ankle.
