Anal margin squamous cell carcinoma

What it means

A squamous cell carcinoma that originates in the skin of the anal margin.

Clinical presentations include pain, bleeding, palpable lump, and discharge. Typically, SCC of the anal margin appears as an ulcerated lesion with rolled everted edges. A significant number of patients are misdiagnosed with an anal fissure, fistula, eczema, or hemorrhoids; therefore a biopsy is recommended for any persistent anal margin lesion not responding to conservative therapy.
