睾丸原发性类癌病例分析并文献复习

Primary carcinoid tumor of testis:a case report and review of the literature

目的探讨睾丸原发性类癌的发生机制、组织来源、临床病理特点和鉴别诊断。方法对1例术前经穿刺活检诊断为右侧睾丸类癌患者,行患侧睾丸根治性切除术。标本送病理检查。结果术中发现右侧精索、输精管、睾丸、附睾鞘膜光滑,与周围组织无粘连浸润,术后纵行剖开标本见肿物呈实性,大小为3.5cm×3.0cm×1.8cm,切开肿瘤内含黄色断面。右侧睾丸大小约4.5cm×5.0cm×5.5cm,内有一灰白色占位,大小约3.5cm×3.0cm×1.8cm。结论睾丸原发性类癌是一种罕见的睾丸肿瘤,其组织起源有争议。该肿瘤应与精原细胞瘤、转移性类癌、支持细胞瘤及粒层细胞瘤等睾丸肿瘤常见病理类型相鉴别。

Objective To discuss the pathogenesis, clinical pathology, differential diagnosis and organize origin of primary carcinoid tumor of testis. Methods One patient diagnosed as carcinoid tumor of testis by puncture biopsy underwent radical testectomy. Results It was found during operation that right deferent duct, testicle and epididymis vaginalis were smooth and had no adhesions with surrounding tissue. The mass was spilt and revealed tumor with 3.5cm× 3.0cm× 1.8 cm kernel, containing yellow cross-section, and there was a mass of 4.5cm × 5.0cm × 5.5cm in the testicle. Conclusion Primary carcinoid tumor of testis is an exceptional testiculoma, and its histogenesis remains controversial. Diagnostically. It is necessary to distinguish it from other testiculoma such as sem inoma, metastatic carcinoid tumor, sertoli cell tumor and granulose cell tumor
