研究背景腺瘤样瘤是睾丸旁区最常见的原发性肿瘤之一。附睾是最常见的受累部位，但也可起源于图尼卡白蛋白膜、精索、图尼卡迷走神经膜和睾丸。细针穿刺细胞学（FNAC）越来越多地用于睾丸旁区域的病变。回顾文献，腺瘤样瘤的细胞学特征报道甚少。我们报告一个发生于睾丸图尼卡白细胞的腺瘤样瘤的细胞学特征。FNAC示病变细胞涂片多为单形肥大细胞团，核椭圆形，核染色质细颗粒，单个核仁小，胞质丰富，胞浆苍白至空泡状。背景显示“虎斑物质“，经典描述为马属。组织学检查证实诊断为腺瘤样瘤的图尼卡albuglast.ConclusionFNAC的腺瘤样瘤构成了一个挑战，当肿瘤发生在其他网站比附睾，因为他们可以他被误认为是睾丸内肿瘤。因此，在阴囊肉瘤的鉴别诊断中，考虑到这种肿瘤是很重要的。(Acta Cytol 2009;53：349-352）
BackgroundAdenomatoid tumor is one of the most common primary neoplasms of the paratesticular area. The epididymis is the most common site of involvement; however, it can also arise from the tunica albuginea, spermatic cord, tunica vaginalis and testis. Fine needle aspiration cytology (FNAC) is being increasingly used for lesions in the paratesticular area. Review of the literature showed very few reports an the cytologic features of adenomatoid tumor. We report the cytologic features of a case of adenomatoid tumor arising from testicular tunica albuginea.CaseA 40-year-old man presented with right-sided scrotal swelling of 1 years' duration. FNAC of the lesion showed highly cellular smears composed of clusters of monomorphic plump cells with oval eccentric nucleus, fine granular chromatin, small single nucleolus and abundant pale to vacuolated cytoplasm. The background showed "tigroid substance, " classically described in seminoma. Histopathologic examination confirmed the diagnosis as adenomatoid tumor of tunica albuginea.ConclusionFNAC of an adenomatoid tumor poses a diagnostic challenge when the tumor arises from sites other than the epididymis because they can he mistaken for intratesticular tumors. It is thus important to consider this tumor in the differential diagnosis of scrotal swellings. (Acta Cytol 2009;53: 349-352)
