Recurrence of testicular germ cell tumor as an angiosarcoma: A case report and review of the literature

Abstract

Testicular germ cell tumor (TGCT) is the most common malignant tumor among young males. TGCT containing a teratoma component may show differentiation into various histopathological subtypes and may rarely recur as angiosarcoma. The present case had TGCT containing a teratoma component, and tumor recurrence occurred first as cartilage tissue and then as an angiosarcoma in the retroperitoneal area. After the diagnosis of angiosarcoma was established, the tumor was considered unresectable. The patient received chemotherapy and radiotherapy. The current study presents a rare case of TGCT, and the researchers also conducted a literature review.
