“…The first case was described in 1895 7 and until 2021 only about 100 cases were reported worldwide, with a male-to-female ratio of 9:1 8 . This disease can manifest at any age, having been reported between the 1st and 8th decades of life, 8 although it is more frequent in the 3rd decade, 9 , 10 probably due to an active sexual life. Among genitourinary hemangiomas, which correspond to 2% of hemangiomas, the urethral location is the rarest.…”
