title: Anastomosing hemangioma: The first case report in the bladder.
abstract: A rare neoplasm, termed 'anastomosing hemangioma' (AH), has been previously described in the genitourinary tract. To date, 29 cases of AH have been reported in the literature, and the case reported in the present study is, to the best of our knowledge, the first AH described in the urinary bladder. It is essential to distinguish AH from malignant vascular tumors due to the different treatments required and the prognosis. The patient in this case study was asymptomatic, with a neoplasm of ~1 cm within the right wall of the bladder. Pathologically, the lesion was predominantly composed of a structure comprising a small vascular cavity and irregularly fenestrated anastomosing vascular channels, with no clear atypia of the endothelial cells.
