Abstract	:	Lichen planus follicularis tumidus (LPFT) is a rare subtype of lichen planus (LP) that has been most commonly described in middle-aged women. LPFT clinically manifests as recurrent cystic follicular nodules that preferentially involve the retroauricular area; concurrent classic LP lesions on the extremities and mucosal surfaces may also be present. Histologically, LPFT demonstrates epithelial-lined follicular cysts filled with orthokeratotic keratin surrounded by a dense lichenoid infiltrate. We present a case of a 67-year-old man with clinical and histopathologic findings consistent with LPFT and discuss differential diagnostic considerations for entities resembling LPFT. Lastly, treatment options for LPFT are reviewed.
