[Malignant epidermoid tumors of the anus. Etiopathogenesis and clinical aspects].

Malignant squamous tumors of the anus (MSTA) are most often carcinomas of the anus (80 to 85%) but remain rare. They occur above all in women between the age of 45 and 70.

Proctalgia fugax is the most distinctive condition, consisting of brief episodes of nocturnal pain recurring at very variable intervals.
