PG - 336-41 AB - OBJECTIVE: To investigate the clinicopathological characteristics of primary testicular mixed germ cell tumor (MGCT). METHODS: We retrospectively analyzed the clinicopathological data of 13 cases of primary testicular MGCT and reviewed other relevant literature. RESULTS: MGCT accounted for 24.1% (13/54) of all the testicular germ cell tumors diagnosed in our hospital. The patients ranged in age from 2 to 53 years, averaging at 28.3 years. All were unilateral cases, 6 in the left and 7 in the right testis, with a left/right ratio of 0.86:1. Morphologically, testicular MGCT displayed a variety of subtypes, embryonal carcinoma in 11 cases (84.6%), seminoma in 8 (61.5%), teratoma in 6 (46.2%), choriocarcinoma in 4 (30.8%) and yolk sac tumor in 4 (30.8%). Nine of the cases (69.2%) were composed of two different germ cell histological elements, 3 (23.1%) composed of three, and 1 (7.7%) composed of five. CONCLUSION: Testicular MGCT is rather rare and most commonly occurs in young men. Its biological behavior, clinical management and prognosis vary with its different histological elements. Therefore accurate pathological diagnosis is essential and immunohistochemistry plays an important role in the diagnosis and differential diagnosis of testicular MGCT.
