Primary non-Hodgkin's lymphoma of the bladder: case report and literature review

Primary Bladder Lymphoma with Extravesical Extension: A Case Report and Literature Review on Prognosis and Clinical Characteristics

Background: Primary bladder lymphoma is generally regarded as having a favorable prognosis due to the predominance of low-grade lymphomas confined to the bladder. However, our investigation reveals that cases with extravesical extension, predominantly involving diffuse large B-cell lymphoma (DLBCL), exhibit a distinct clinical course with varied prognostic outcomes. Methods: In this report, we present and analyzed the clinical features and outcomes of 47 patients with primary bladder lymphoma with extravesical extension, including the case that we experienced. Results: An 77-year-old man who experienced fever, anorexia, and general malaise was referred to our hospital. Initial laboratory tests indicated severe renal failure, pyuria, and Escherichia coli bacteremia, accompanied by diffuse thickening of the bladder walls and increased attenuation in the surrounding adipose tissues. Initially misdiagnosed with a severe urinary tract infection leading to sepsis, the patient was treated with antibiotics and hemodialysis. Upon readmission due to abdominal pressure, imaging identified an intra-abdominal mass connected to the bladder wall. A bladder biopsy was performed, resulting in the diagnosis of primary bladder DLBCL with perivesical extension, classified as germinal center B-cell type. Taking inspiration from this case, the review of 46 patients was implemented. As a result, we resolved that primary bladder lymphoma often includes indolent types like Mucosa-associated lymphoid tissue lymphoma, but cases with extravesical expansion are predominantly DLBCL. Conclusions: This case emphasizes the diagnostic complexities of distinguishing primary bladder lymphoma from urinary tract infections and underscores the prognostic implications of extravesical extension. Our comprehensive review of the literature on primary bladder lymphomas with extravesical involvement highlights the clinical characteristics, therapeutic challenges, and need for heightened diagnostic vigilance and tailored treatment strategies for this subset of patients.

Primary Bladder Non-Hodgkin Lymphoma: A Case Report

Primary bladder lymphoma, a rare form of non-Hodgkin's lymphoma, is diagnosed through histopathology and immunostaining. Most bladder lymphomas are of the B-cell type, with a higher incidence in women and often presenting with hematuria. This report details an exceptionally rare case of primary bladder T-cell lymphoma. A 50-year-old male, without hematuria or other symptoms, was diagnosed during a routine ultrasound. A computed tomography scan showed a tumor located in the anterior, right, and posterior walls. The patient underwent transurethral resection of the bladder lesion. Pathological examination of the tumor showed that it was composed of lymphoid tissue, in accordance with peripheral T-cell lymphoma of non-Hodgkin subtype.

Epstein-Barr virus-positive primary diffuse large B-cell lymphoma of the urinary bladder: a case report

Primary non-Hodgkin's lymphoma (NHL) of the urinary bladder is a rare event, with diffuse large B-cell lymphoma (DLBCL) being the most common form of NHL and urinary bladder lymphoma. It is an aggressive tumour with a poor prognosis if not recognised and treated early. The diagnosis is supported by radiological imaging and confirmed by histology, which shows the characteristic morphology of this lesion with further immunohistochemical analysis. Here we present a case of Epstein-Barr virus-positive DLBCL confirmed by an immunohistochemistry panel, along with a brief review of the literature focusing on diagnosis, treatment and outcome of this rare tumour.

Malignant lymphoma occurring simultaneously in the urinary bladder wall and bilateral renal parenchyma: A case report

A 67-year-old man was admitted to hospital with acid regurgitation, acute right lower abdominal pain and mild fever. Multiple suspicious mass lesions were detected in the patient's kidneys, the right side wall of his bladder and the right lower ureter, using CT urography and PET-CT. He underwent palliative surgery of the bladder and percutaneous renal biopsy. Postoperative histopathological examination and immunohistochemical staining indicated that the tumor was consistent with diffuse large B-cell lymphoma (DLBCL). Although DLBCL is by far the most common type of non-Hodgkin's lymphoma, it is rare for DLBCL to simultaneously involve the kidneys, bladder and the lower ureteric tract.
