Carcinoids of the testis are rare tumours developing in three different ways: 1. It may differentiate within a teratoma, 2. it may be a metastasis of a "loco alieno" seated carcubiud abd 3. it may represent a real primary carcinoid. The observation of a primary testicular carcinoid in a man aged 55 years afforded the opportunity to study such a tumor for the first time by electron microscopic and fluorescence microscopic methods. Thereby, it could bw shown, that this testicular carcinoid corresponds to the carcinoids of the lower small gut. According to the specific ultrastructure of the intracytoplasmic granules it must derive histogenetically from an EC-cell. At the moment it cannot be decided whether the primary testicular carcinoid represents an autochthonous tumor of the male gonad or solely a teratoma with one-sided differentiation in the sense of a simplified teratoma.
睾丸类癌是罕见肿瘤，其发展方式有三种：1. 它可能在畸胎瘤内分化；2. 它可能是位于别处的类癌转移而来；3. 它可能是真正的原发性类癌。一名55岁男性原发性睾丸类癌的病例，首次提供了通过电子显微镜和荧光显微镜方法研究此类肿瘤的机会。由此可以证明，这种睾丸类癌与下消化道的类癌相符。根据胞质内颗粒的特定超微结构，它在组织发生上必定源自肠嗜铬细胞。目前尚无法确定原发性睾丸类癌是男性性腺的原发肿瘤，还是仅仅是一种在简化畸胎瘤意义上具有单侧分化的畸胎瘤。
