睾丸间质细胞瘤6例临床病理分析并文献复习(1)
[摘要] 目的 探讨睾丸间质细胞瘤(leydig cell tumors,LCT)的临床病理特点及鉴别诊断。 方法 对6例LCT患者临床病理资料进行回顾性分析和随访,并复习相关文献。 结果 6例患者均为男性,年龄45~79岁,平均59岁。常见症状为阴囊肿大。组织病理学表现为片状分布的大的多角形细胞,胞浆嗜酸性,细胞核呈圆形或者卵圆形,可见一个或多个核仁,未见Reinke结晶。免疫组化标记显示肿瘤细胞表达a-inhibin、Melan A、Calretinin等。6例患者中5例行根治性切除,另1例因前列腺增大行前列腺及睾丸切除术。4例患者随访至今未出现复发及转移。 结论睾丸LCT是一种少见的肿瘤,以良性为主,诊断及鉴别诊断依赖镜下形态及免疫组化化学染色。治疗主要采取睾丸切除术。

[Abstract] Objective To investigate the clinicopathological characteristics and differential diagnosis of leydig cell tumors (LCT). Methods The clinical and pathological data of 6 patients with testicular LCT were retrospectively analyzed and followed up, and the relevant literature was reviewed. Results 6 patients were all male, aged from 45 to 79 years (mean 59 years). The common symptom was scrotal swelling. Histopathology showed a patchy distribution of large polygonal cells, and the cytoplasm was eosinophilic. Nucleus was round or oval, showing one or more nucleoli, without Reinke crystallization. Immunohistochemical staining showed that a-inhibin, Melan A and Calretinin were expressed in tumor cells. Among 6 patients, 5 patients were given radical resection, and 1 patient was given prostatectomy and orchiectomy due to enlarged prostate. No recurrence or metastasis was observed in 4 patients till now. Conclusion Testicle LCT is a rare type of tumor, mainly benign, and the diagnosis and differential diagnosis depends on microscopic morphology and immunohistochemical staining. The treatment mainly adopts orchiectomy.

睪丸间质细胞瘤(leydig cell tumors,LCT)是一种罕见的源于Leydig细胞的性索间质肿瘤,占所有睾丸肿瘤的3%。该肿瘤通常是良性的,但约10%的LCT显示恶性生物学行为[1]。在临床上可以引起内分泌功能紊乱,而且具有一定的恶性潜能,因此需要及早治疗。本文收集6例LCT并结合文献复习,探讨其临床、影像学、病理特征以及诊断与鉴别诊断。
1 资料与方法
1.1临床资料
收集浙江省台州市肿瘤医院病理科2013年6月~2015年6月诊断的2例和浙江省绍兴市人民医院病理科2010年1月~2015年12月诊断的4例LCT患者,对此6例LCT患者的临床病理资料进行回顾性分析并复习相关文献。本组6例患者均为男性。例1,45岁,以“阴囊肿大半年”入院。患者半年前在无明显诱因下出现双侧阴囊肿大。入院后体格检查,右侧睾丸肿大如鹅蛋,质韧,无明显触痛;左侧睾丸肿大如鸡蛋,质韧,无明显触痛。B超提示双侧睾丸占位。CT示双侧睾丸内不规则形肿块,呈分叶状,左侧较大,增强后明显强化,内似血管穿过。腹主动脉旁、腹膜后及盆壁内未见明显淋巴结肿大。例2,69岁,因“左腹股沟区可复性肿块1年余”入院。患者1年前无明显诱因下发现左腹股沟区包块,约鸡蛋大小,当时局部无红肿,平卧及休息时可使之回纳,站立时肿块突出,尤以下午及劳累后明显,有时伴腹痛。肿块呈缓慢性渐进性增大,近期患者自觉肿块突出频繁,回纳较前困难。1月前患者肿块坠入阴囊,但无明显腹痛腹胀等不适。门诊拟“左腹股沟疝”收住入院。入院体格检查,左腹股沟站立位时可见一6 cm×8 cm大小肿块,压之不能回纳,质软,无压痛,平卧位不能消失,坠入阴囊。阴囊B超示右侧睾丸占位,右侧睾丸鞘膜积液。例3、例4、例5患者年龄分别为47岁、56岁、60岁,临床均因发现阴囊肿物而入院。B超提示睾丸占位性病变,临床考虑肿瘤而行睾丸切除术。例6,79岁,以“排尿不畅4年,尿潴留10 d”入院。DRE:前列腺2度增生,中间沟消失,质韧,无明显结节,无触痛。B超示:前列腺肥大,T-PSA 33.69 ng/mL。 (徐欣华 张冬梅 魏建国)
