OBJECTIVE: 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.
METHODS: Clinicopathological description of a case of plasma cell granuloma of the renal pelvis with light chain immunohistochemical study.
RESULTS: 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.
CONCLUSIONS: 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.
