Generalized lentiginosis refers to generalized lentigines without systemic abnormalities, characterized by multiple brown or black macules owing to increased proliferation of melanocytes. There are also lentiginosis syndromes associated with systemic abnormalities such as Peutz-Jeghers syndrome, Leopard syndrome, and Carney complex. Generalized lentiginosis can be diagnosis by patient's history, physical and laboratory examination, and histopathology. We report an 11-year-old boy who presented with multiple dark brown macules, varying in size, but less than 0.5 cm, with no abnormalities of other systemic organs.
