Metastatic hidradenocarcinoma, case description and literature review. Hidradenocarcinoma metastásico, descripción de un caso y revisión de la literatura.

Abstract

The hidradenocarcinoma is a rare neoplasm. There are no consensus guidelines for the local or systemic treatment of this disease. We describe a case of a 71-year-old male with a slow growing lesion that was treated with a non oncologic resection. The pathologic report informed a clear cell hidradenocarcinoma. After the diagnosis the chest scan documented metastatic disease. It was proposed a first line of chemotherapy using capecitabine, with progression after 5 cycles. The patient refused other chemotherapy lines. The hidradenocarcinoma usually presents as a long standing asymptomatic nodular lesion in the skin. Most of the diagnoses are made incidentally. The treatment includes surgery and nodal dissection. Half of the patients present local failure and eventually metastatic disease. The chemotherapy is used with a variety of drugs and results.
