[A Case of Autopsy of Sarcomatoid Carcinoma of the Penis with Metastasis to the Right Ventricle of the Heart].

A 75-year-old man with a history of early gastric cancer, phimosis and bronchial asthma experienced pain and palpated a mass in the penis in March 2015. After 2 months, he noticed bleeding from the tumor and visited our hospital. Pelvic computed tomography and magnetic resonance imaging revealed a pelvic tumor, bilateral lymphadenopathy, and para-aortic lymphadenopathy. After partial penis excision and left inguinal lymph node biopsy, the pathological result was penile squamous cell carcinoma sarcomatoid type, stage IV. As controlling bleeding from the left inguinal lymph node metastasis was difficult, radiotherapy and appropriate debridement were performed. However, the size of the metastasis increased, and the general condition of the patient gradually worsened, the patient died two months after the operation. On pathological autopsy, metastasis to the right ventricle was observed in addition to the left inguinal lymph node metastasis. Herein, we present the first autopsy report of metastatic squamous cell carcinoma sarcomatoid type in Japan, along witha literature review.
