Porokeratotic lichen planus of the lower extremities

Unusual presentation of porokeratotic lichen planus: Histology, dermoscopy and confocal microscopy imaging of a rare condition

“…It is notable for its asymptomatic nature and mainly localization on the lower extremities, while frequently it shows a tendency to generalize to the rest of the body, including mucous membranes and palmo‐plantar surfaces. 1 , 2 Although the advanced stage of pLP often bears resemblance to other dermatological entities, early‐stage pLP presents diagnostic complexities due to the paucity of lesions and their potential nonspecific morphological attributes. Thus, we present the case of a 71‐year‐old male patient who comes to our attention for a suspected epithelioma, that is, for the appearance of an asymptomatic palpable lesion on the left lower limb approximately half a year ago.…”
