Bladder teratoma with pilimiction in a male adolescent

Teratomas are tumors consisting of two or three germ layers, seen commonly during childhood. Mature teratomas are benign and demonstrate well differentiated tissues such as sebaceous glands, hair, and teeth. Bladder is a very rare extragonadal site for teratoma, moreover so in adults. Presentation may vary from with irritative lower urinary tract symptoms or urinary retention to pilimiction (passage of hair in the urine). We hereby present a case of mature teratoma of the urinary bladder, with a classical symptom of pilimiction, in a 22-year-old male patient, which to our knowledge is the first male case reported in the literature.
