Porokeratosis is a skin condition marked by the development of benign plaques, featuring a distinctive raised ridge and a flat center, which can lead to squamous cell carcinoma if untreated.
The condition is mostly found on extremities, with rare occurrences on the lip, as highlighted by the report of three cases involving lip lesions.
Treatment options included cryotherapy, which failed in two patients, while one patient was successfully treated with a shave biopsy, and another was lost to follow-up.
