摘要

简介:睾丸旁肿瘤占泌尿生殖系统肿瘤的2%。它们是起源于间质组织的良性肿瘤,生长缓慢,无明确病因,可出现在任何由平滑肌组成的组织中。注意平滑肌瘤,在这个部位被认为是一种罕见的肿瘤,因此它的诊断经常与睾丸肿瘤混淆。临床病例:作者提出一个病例56岁的男性患者入院泌尿科门诊,在右侧睾丸生长缓慢的无痛性肿块,3年的发展。在进一步检查后,他接受了右腹股沟睾丸切除术。手术标本的组织病理学分析和免疫组织化学特征显示间充质瘤与非典型睾丸旁平滑肌瘤相一致,具有边缘性行为和惰性生长。讨论:这是一种罕见的良性病理,其病因不明,很容易诊断为睾丸起源。因此,本报告提出了将这一实体纳入医学知识的目标,以便就今后的办法进行合作。

Raro Caso de Leiomioma Paratesticular
Introduction: Paratesticular tumors account for 2% of genitourinary neoplasms. They are benign neoplasms originating from the mesenchymal tissue, of slow and indolent growth, with no definite etiology, and can appear in any tissue composed of smooth muscle. Note the leiomyomas, which are considered a rare neoplasia in this location, so that their diagnosis is often confused with testicular tumors. Clinical Case: The authors present a case of a 56-year-old male patient admitted to the urology outpatient clinic with a large painless mass in the right testis of slow growth and a 3-year evolution. After further examination, he underwent right inguinal orchiectomy. The histopathological analysis and immunohistochemical profile of the surgical specimen showed a mesenchymal neoplasia compatible with atypical Paratesticular Leiomyoma, with borderline behavior and indolent growth. Discussion: This is a rare benign pathology whose etiology is frankly unknown and easily diagnosed as testicular origin. Therefore, this report sets out the objective of introducing this entity into medical knowledge in order to collaborate on future approaches.
