Tip 182: slate-grey naevus

These are blue or slate-grey macular lesions (previously called a Mongolian blue spot) with variably defined edges, seen most commonly over the pre-sacral area.

They may be solitary or numerous and can involve large areas.

More than 80% of Afro-Caribbean and Asian infants have them compared with <10% of Caucasian infants. Malignant degeneration does not occur.
