Abstract

Lichen planus follicularis tumidus (LPFT) is a rare variant of follicular lichen planus that predominantly affects the postauricular region, although cases involving the nasal ala and vulva have also been reported. The distinctive histopathology of LPFT can lead to diagnostic confusion with plaque parapsoriasis, lichenoid keratosis, and folliculotropic mycosis fungoides. We herein report a case of LPFT in a 54-year-old woman presenting with a vulvar lesion that exhibited plaque-like and verrucous features. Histopathologically, the lesion demonstrated typical lichenoid inflammation that surrounded dilated follicular infundibula. The patient achieved complete resolution following surgical excision.
