To report a rare case of plasma cell granuloma of the renal pelvis. To our knowledge, only five cases have been reported in the literature.
Clinicopathological description of a case of plasma cell granuloma of the renal pelvis with light chain immunohistochemical study.
A young male patient with a radiologically benign mass in the right renal pelvis extending into the upper calices that caused hematuria is described. The diagnosis was suggested during the intraoperative study of the mass that was suggested by pyelotomy (conservative surgery). Immunohistochemical study confirmed the initial diagnosis.
Although this condition is rare, plasma cell granuloma, an inflammatory pseudotumor, can occur in the urinary tract and should be considered in the differential diagnosis of mass lesions. Histopathological diagnosis requires a complete study of the entire tumor and the use of immunohistochemical techniques to discard plasmacytic non-Hodgkin lymphoma or neoplastic plasma cell proliferation.
报告一例罕见的肾盂浆细胞性肉芽肿病例。据我们所知，文献中仅报道过5例。
对一例肾盂浆细胞性肉芽肿病例进行临床病理描述，并进行轻链免疫组化研究。
描述了一名年轻男性患者，其右肾盂有一个放射学表现为良性的肿块，延伸至上盏，导致血尿。在肾盂切开术（保守手术）对肿块进行术中研究时提出了诊断。免疫组化研究证实了初步诊断。
尽管这种情况罕见，但浆细胞性肉芽肿作为一种炎性假瘤，可发生于尿路，在肿块病变的鉴别诊断中应予以考虑。组织病理学诊断需要对整个肿瘤进行全面研究，并使用免疫组化技术以排除浆细胞性非霍奇金淋巴瘤或肿瘤性浆细胞增殖。
