An invasive squamous cell carcinoma of the ankle: a case report.

ISCC of the lower extremities is a rare disease that almost never affects the ankle and is frequently treated inappropriately since it mimics chronic wounds. It is important to have an index of suspicion in patients with a history of chronic irritation to the area of interest. Surgery is the primary option if ICCS is detected. Clear tumour margins are important, and, if done well, excision should be curative.
