Paratesticular fibrous pseudotumors are rare, benign proliferations that pose significant diagnostic challenges due to their resemblance to fibroblastic soft tissue tumors. We report a young adult male who presented with a right scrotal mass, initially considered to be a solitary fibrous tumor (SFT) but ultimately diagnosed as a fibrous pseudotumor. Histopathologic examination revealed a well-circumscribed, hyalinized, hypocellular spindle cell mass with inflammatory features. Despite the marginal Signal transducer and activator of transcription 6 (STAT6) positivity, extensive consultation confirmed the benign nature of the mass. This case highlights the importance of meticulous diagnostic processes, including advanced imaging and intraoperative assessments, to avoid unnecessary orchiectomy. It also highlights the characteristic histologic features that differentiate these benign entities from malignant counterparts, ensuring appropriate management and a favorable prognosis.
睾丸旁纤维性假瘤罕见,属于良性增生,因其与纤维母细胞性软组织肿瘤相似,给诊断带来重大挑战。我们报告了一名年轻成年男性,其右侧阴囊出现肿块,最初被认为是孤立性纤维瘤(SFT),但最终诊断为纤维性假瘤。组织病理学检查显示为边界清楚、玻璃样变、细胞稀少的梭形细胞肿块,并伴有炎症特征。尽管信号转导和转录激活因子6(STAT6)呈边缘阳性,但广泛会诊后确认该肿块为良性。该病例强调了细致诊断过程的重要性,包括先进的影像学检查和术中评估,以避免不必要的睾丸切除术。它还突出了将这些良性病变与恶性病变区分开来的特征性组织学特征,确保适当的管理和良好的预后。
