Mongolian blue spots
Definition Mongolian spots are flat, blue or blue-gray skin markings that commonly appear at birth or shortly thereafter. See also: Rashes Alternative Names Mongolian spots; Congenital dermal melanocytosis; Dermal melanocytosis Causes, incidence, and risk factors Mongolian blue spots are common among darker skinned persons, such as those who are of Asian, East Indian, and African descent. Symptoms Mongolian spots are non-cancerous skin markings and are not associated with disease. The markings may cover a large area of back. Occasionally, Mongolian blue spots are mistaken for bruises, which can raise a question about possible child abuse. It is important to recognize that Mongolian blue spots are birthmarks, NOT bruises. Symptoms include: - Blue or blue-gray spots on the back, buttocks, base of spine, shouders, and other body areas
- Flat area with irregular shape and unclear edges
- Normal skin texture
