Familial Lassueur-Graham-Little-Piccardi syndrome.

Lassueur-Graham-Little-Piccardi syndrome (LGLPS) is a rare lichenoid dermatosis characterized by progressive cicatricial alopecia of the scalp, loss of pubic and axillary hairs and keratosis pilaris. The syndrome is considered a form of follicular lichen planus (LP). Although the familial occurrence of LP is a well-described phenomenon, no familial case of LGLPS has ever been reported. We describe the occurrence of LGLPS in a mother and her daughter. HLA typing revealed HLA-DR1 in both patients. Topical tacrolimus was of partial benefit in the daughter.
