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 explore the primary carcinogenesis of testicular carcinogenesis, source of tissue, clinicopathological features and differential diagnosis. Methods One case of right testicular carcinoid was diagnosed by biopsy before operation, and radical operation was performed on the ipsilateral testicular. Specimens sent for pathological examination. Results The right spermatic cord, vas deferens, testes and epididymis were found to be smooth and noninvasive infiltration into the surrounding tissues during the operation. The size of the spermatic cord was 3.5cm × 3.0cm × 1.8cm, Cut the tumor with yellow section. Right testis size of about 4.5cm × 5.0cm × 5.5cm, there is a gray white placeholder, the size of about 3.5cm × 3.0cm × 1.8cm. Conclusion Primary testicular carcinoid tumor is a rare testicular tumor, the origin of the controversial organization. The tumor should be differentiated from the common pathological types of testicular tumors such as seminoma, metastatic carcinoid, supportive cell tumor and granular cell tumor.
