Perianal basal cell carcinoma.
BACKGROUND: A case of basal cell carcinoma (BCC) of the perianal region is reported. This tumor is extremely rare in this location and behaves rather innocently. OBJECTIVE: Clinical and histopathologic characteristics of perianal BCC, as well as the choices of treatment, are outlined. CONCLUSION: The tumor should be histologically distinguished from basaloid carcinoma of the anus, which is much more aggressive and metastasizes early, thus requiring a different therapy.
