Porokeratosis mibelli [Porokeratozis mibelli]
MetadataShow full item record
Porokeratosis mibelli (PM) is a rare, chronic keratinization disorder that has unknown etiology and may be inherited. PM is considered a premalign lesion, characterized by thin plaques with atrophic center and surrounded by a hyperkeratotic border. PM is more common in men and is usually located in the extremities, but occasionally the involvement of the face and genital area is also seen. Because of the potential for malignant degeneration, treatment and follow-up of PM must be performed. Here, we present a 17-years-old female patient who diagnosed with PM in the face region and performed cryotherapy and PM is discussed in the light of the literature.
