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.


CONCLUSIONS
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.
