Abstract

Adenomatoid tumor is a benign neoplasm of a mesothelial origin, and it usually occurs in the reproductive organs, especially in the epididymis. The author experienced a case of adenomatoid tumor involving the tunica albuginea and testicular parenchyme without any evidence of epididymis involvement. The patient was a 36-year-old man with a painless scrotal mass that he had experienced for 2 months, and this mimicked testicular neoplasia, including metastatic carcinoma, or other benign lesions. The imprint cytology of the tumor showed a hypocellular smear with mainly arranged cells in cohesive monolayered clusters along with occasional singly dispersed cells and naked nuclei in a clean background. The cellular clusters formed vague glandular and cord-like structures. The tumor cells were large polygonal to columnar cells with a relatively monomorphic appearance. The nuclei were oval to round shape and they showed vesicular, fine chromatin and inconspicuous nucleoli. The cytoplasm was moderate to abundant, and it contained fine vacuoles in some tumor cells. Mitoses and cellular pleomorphism were not present. Awareness of the cytologic finding of this lesion is necessary to screen or differentiate a testicular or paratesticular mass before and/or during surgery because the cytology may be useful as a diagnostic tool. Pathologists should be aware of the cytologic features of common lesions in this anatomic region so as to avoid performing aggressive and unnecessary surgical procedures.
白膜腺瘤样瘤的触摸印迹细胞学分析1例
腺瘤样肿瘤是一种起源于间皮的良性肿瘤,通常发生在生殖器官,尤其是附睾。本文报告一例腺瘤样肿瘤累及白膜及睾丸实质,但未累及附睾。患者为36岁男性,2个月前出现无痛性阴囊肿块,表现为睾丸瘤样病变,包括转移癌或其他良性病变。肿瘤的印迹细胞学显示低细胞涂片,细胞主要排列成内聚的单层簇状,偶尔有单个分散的细胞和裸露的细胞核。细胞簇形成模糊的腺状和索状结构。肿瘤细胞呈大多边形至柱状细胞,形态相对单一。细胞核呈卵圆形,呈泡状,染色质细,核仁不明显。部分肿瘤细胞胞质中至丰富,胞质中含有细小的液泡。不存在有丝分裂和细胞多形性。了解这种病变的细胞学发现对于在手术前和/或手术中筛查或区分睾丸或睾丸旁肿块是必要的,因为细胞学可能是有用的诊断工具。病理学家应了解该解剖区域常见病变的细胞学特征,以避免进行侵略性和不必要的外科手术。
