| ABSTRACT |
|
Inflammatory pseudotumors of the urinary bladder are rare, benign and nonepithelial tumors characterized by proliferative myofibroblast, fibroblast, histiocytes, and occasionally by plasma cell and lymphocytes.
Microscopically, inflammatory pseudotumors present as either pedunculated intraluminal tumors that can be seen readily during cystourethroscopy or as submucosal mural lesions that may be easily overlooked. Histological features of this benign lesion mimic those of malignant neoplasm but their clinical course is benign. Although inflammatory poseudotumors can occur anywhere in the body, they are rare in the bladder. We report a case in which induced acute urinary retention and describe the clinical presentation, and radiographic and histologic findings. |
