A Rare Case of Lichen Planus Follicularis Tumidus Involving Bilateral Retroauricular Areas.

Lichen planus follicularis tumidus (LPFT) is an extremely rare variant of lichen planus characterized by white to yellow milia-like cysts and comedones on a violaceous to hyperpigmented plaque most commonly involving retroauricular area. Clinically, it resembles milia . It is usually asymptomatic, more common in middle-aged females. Histopathologically, it has features of lichen planopilaris along with follicular cysts in dermis surrounded by lichenoid infiltrate. We are reporting a case of LPFT in a 62-year-old male patient involving bilateral retroauricular areas due to the rarity of this condition.
