Sarcomatoid carcinoma of the penis

We encountered a 63-year-old male with a sarcomatoid carcinoma of the penis accompanied by metastasis to the bilateral inguinal lymph nodes and lungs. He noticed a penile mass, but neglected it. The mass rapidly increased in size, forming an ulcer, and began to disintegrate. He visited our hospital 4 months after noticing the mass. After cystostomy and blood transfusion, surgical resection was performed. A diagnosis of a squamous cell carcinoma with a sarcomatoid carcinoma of the penis was made. After the operation, best supportive care (BSC) was selected. We made efforts to maintain his quality of life (QOL), and he died 3 months after the operation.
