A rare case of anal porocarcinoma treated by electrochemotherapy.

We report the case of an old woman with an eccrine porocarcinoma unusually localized in the perianal area treated by electrochemotherapy, a new technique, emerging as a very effective local treatment of different skin metastases and selected primary tumors. Electrochemotherapy was performed taking into account patient wishes and refusal of demolitive surgery. The electrochemotherapy treatment was well tolerated by the patient, it gave an excellent clinical response and a complete clinical regression with no sphincter dysfunction and signs of relapse observed during follow-up. The case is of particular interest for the exceptional localization of porocarcinoma for the first time treated by electrochemotherapy in this area. Electrochemotherapy could be considered as an alternative option for selected cases of cutaneous tumors.
