摘要：

Pseudomelanosis (PM) is a rare, benign, condition that is characterized by deposition of melanin and/or melaninlike pigment in mucosal cells and macrophages and is best known as the entity pseudomelanosis coli. Pseudomelanosis primary of the urinary bladder has been reported only in a handful of cases worldwide. This article reports an extremely rare case of pseudomelanosis of the urinary bladder in a 79-year-old male with a history of macroscopic painless hematuria.
