Male hermaphroditism with rare malignant transformation of gonadal organs: a case report.

A 27-year-old man was admitted to the hospital after a year of marriage due to infertility. During laparoscopic exploratory surgery, the presence of a retrovesical uterus was clearly observed, and the gonadal organs were visible on both sides. However, the testicles or ovaries were not identifiable, nor were the spermatic vessels and fallopian tubes at the joint. Intraoperative bilateral gonad biopsy was performed. Cryopreservation of the right gonadal gland revealed gonadoblastoma and malignant germinoma (asexual tumor/seminoma) with sclerosis and atrophy of testicular tissue. No proliferation of germ cells and sertoli cells was observed in spermatic tubule. The left gonad was diagnosed as a gonadoblastoma. Finally, total hysterectomy and bilateral gonadal tumor organectomy were performed to seal the vaginal stump. Local radiotherapy was administered after surgery. In general, tumors were found on both sides of the gonads, especially gonadoblastoma and malignant germinoma on the right side and gonadoblastoma on the left side.
