title: [A Case of Penile Squamous Cell Carcinoma, Sarcomatoid Subtype].
abstract: A 70-year-old man was referred to our department for further examination and treatment of a painless penile mass of about 2cm. The patient first noticed the mass onlya few weeks before presentation. Diagnostic biopsy was interpreted as leiomyosarcoma. Through systemic examinations the clinical stage of his disease was diagnosed as cT2N0M0 and we performed total penectomy. Histopathological examination for the totallyresected tissue disclosed the concomitant presence of regions compatible to squamous cell carcinoma and the results of immunohistochemistrywere compatible with the diagnosis of squamous cell carcinoma, sarcomatoid subtype of the penis. One month after the surgery, multiple metastases to left inguinal lymph nodes and lungs developed, for which systemic chemotherapy by doxorubicin was ineffective and the patient died of respiratoryinsufficiencyfive months after presentation.
