A newborn developed multiple black-brown macules on the right side of the dorsal tongue and was referred to our department. The tongue surface was smooth and the boundary clear. Pigment was evident only on the tongue. Direct microscopic examination was negative. Up to the age of 4 years, the lesions increased a little in size and became slightly brighter. The patient was asymptomatic. Although biopsy has not been performed, given the patient’s age, the clinical signs and course imply congenital melanotic macules of the tongue. Outpatient follow-up is continuing.
