Blue naevus is a dark blue, gray or black lesion consisted of dermal melanocytes and usually found on face, scalp, or on the dorsum of hands and feet. Two well defined histologic and clinical variants, designated as "common" and "cellular", have been recognised. An unusual case of accidentally detected common blue naevus of the lungs has been reported. The specimen of lung tissue was taken during autopsy of a 62-year old woman who died of myocardial infarction. Microscopic analysis revealed the area containing melanocytes filled with melanin pigment.
