Özet
Dear Editor,
Lichen planus follicularis tumidus (LPFT) is an extremely rare variant of lichen planus (LP). Clinically, it is characterized by white-to-yellow milia-like cysts and comedones, and red dish-to-violaceous plaques. Although it is usually asymptomatic, it may be slightly itchy. Its most common location is the retroauricular region, but it has also been rarely described in the bilateral retroauricular area and on the cheeks and neck. Histopathology of LPFT shows slightly hyperkeratotic or normal epidermis, which is accompanied by follicles and cysts, filled with orthokeratotic keratin, surrounded by dense lichenoid band-like lymphocytic infiltrate, wedge-shaped hypergranulosis, vacuolar degeneration of the basal zone, pigment incontinence and rare colloid bodies in the papillary dermis.4 This characteristic morphology and histopathology of LPFT clearly resembles lichen planopilaris. Here we report a rare case of LPFT concomitant with Hashimoto’s thyroiditis.
