Nonseminomatous Germ Cell Tumors

Teratomas are nonseminomatous germ cell tumors composed of elements derived from more than one germinal layers (endoderm, mesoderm, and ectoderm). Malignant transformation of teratoma in the testis is well known; however, benign somatic neoplasm arising in a testicular teratoma is a rare occurrence. We report a case of meningothelial variant of meningioma arising in a pure and mature teratoma of the testis in a 5-year-old boy. Immunohistochemistry was positive for epithelial membrane antigen and vimentin. To our knowledge, this is the first report of meningothelial meningioma in a prepubertal testicular teratoma.

Work Up

Germ cell tumors (GCTs) are a histologically heterogeneous group of tumors that arise from the primitive germ cell of the embryonic gonad. Choriocarcinoma is a variant of GCTs that is prone to hematogenous metastasis to the liver, lung, and brain. Cutaneous metastasis in choriocarcinoma is rarely encountered with only a few cases reported in literature. We report the case of a 28-year-old male presenting with lower back pain that, upon further work-up, was diagnosed with pure choriocarcinoma of the testes. Around 9 months after his initial presentation, he developed a cutaneous back lesion. Microscopic examination confirmed the presence of choriocarcinoma composed of mononuclear cytotrophoblasts which interweave with multinucleated syncytiotrophoblasts. The patient passed away 3 weeks after the onset of cutaneous metastasis.
