Penile strangulation is a rare event that requires emergency treatment. Metal rings are most commonly used on the penis for autoerotic or aggressive purposes or to enhance sexual performance. We report a case of a 19-year-old male patient undergoing psychiatric treatment at the Dalal Xél health center in Fatick, who was admitted to the emergency department of Kaffrine Regional Hospital (in Senegal), for penile strangulation by a metal ring. The ring had been placed at the root of the penis three days earlier. The patient had no urinary disorders. Treatment consisted of removing the ring and providing psychiatric care. However, to prevent urinary and sexual complications, treatment must be provided early. Through this observation and data from the literature, the authors report the subtlety of the management of this pathological situation, highlighting the psychotic context which favors this type of self-aggressive behavior.
