Premature Sebaceous Hyperplasia in an Adolescent Boy

  Sebaceous hyperplasia is a common, benign condition of the sebaceous glands in adults of middle age or older, occurring primarily on the face and neck. In adolescent or young adult patients, it is a rare entity called premature sebaceous hyperplasia (PSH). Previous reports indicate that the onset of PSH occurs during or shortly after puberty, with an average age‐at‐onset of 19 years. Here we present an extremely rare prepubescent case of PSH that developed on the right side of a boy’s neck when he was 8 years old.
