Inherited Patterned Lentiginosis In Blacks (IPLIB) is a benign distribution of pigmented macules that may occur in darker-skinned individuals. A similar condition entitled "Pigmented macules of bony prominences" was recently described and is more common in patients with fair skin--mostly red hair [JAAD 2016;74;383-5]. Pr. Thierry Passeron, MD, PhD, one of the lead authors of that article pointed out in a personal communication that IPLIB typically has the involvement of the lips and sometimes palms and soles that they never observed in their series.
The patient has a striking lentiginous pigmentation of the central face and lips without mucous membrane or internal involvement. Inheritance is autosomal dominant. Lentigines may be seen on the elbows, knees, and buttocks as well.
No treatment is needed. The 510 nm dye laser may be used.
