生殖器平滑肌的错构瘤性增生并不常见，如果病理学家不熟悉阴囊肉膜的正常显微镜下表现，则很容易被忽略。我们描述了一个60岁的阴囊错构瘤性增生的患者，在该患者中，对区域组织学的不完全了解导致了最初的诊断问题。在组织学检查中，病变包括一个膨胀的，无包膜的，相对局限的平滑肌增生伴随着肌肉小动脉和突出的神经分支嵌入在一个密集的胶原化基质。这些特征在临床和组织学上与该部位所有既往报告的病变不同。我们强调了我们的病例与生殖器平滑肌瘤之间的组织学差异，以及与贝克尔痣相关的错构瘤性平滑肌增殖谱，以及先天性和获得性平滑肌错构瘤。
Hamartomatous proliferations of genital smooth muscle are uncommon and may be easily overlooked if the normal microscopic appearance of the scrotal dartos is unfamiliar to the pathologist. We describe a hamartomatous proliferation of the scrotum in a 60‐year‐old patient in which incomplete knowledge of the regional histology caused initial problems in diagnosis. On histologic examination, the lesion consisted of an expansile, unencapsulated, relatively circumscribed proliferation of smooth muscle accompanied by muscular arterioles and prominent nerve branches embedded in a densely collagenized stroma. These features are dissimilar both clinically and histologically from all previous reported lesions at this site. We highlight the histologic differences between our case and genital leiomyomas, and the spectrum of hamartomatous smooth‐muscle proliferations associated with a Becker nevus, and congenital and acquired smooth muscle hamartomas.
