Primary urinary bladder lymphoma: presentation with bilateral hydronephrosis
, 23
Abstract
Primary urinary bladder lymphoma is an extremely rare entity, accounting for approximately 0.2% of all extranodal lymphomas and less than 1% of all urinary bladder tumours. This neoplasia usually occurs more frequently in female and elderly patients, and the most common histological type is diffuse large B-cell lymphoma. As it has non-specific clinical and imaging characteristics, its diagnosis requires a histopathological evaluation, since it can be confused with other urinary bladder neoplasms. The management of this neoplasia is mainly based on immunochemotherapy with the R-CHOP regimen, which has shown good outcomes. This article presents the case of an elderly patient who presented with isolated haematuria and hydronephrosis whose subsequent studies revealed the presence of a primary urinary bladder lymphoma consistent with diffuse large B-cell lymphoma.
