Porokeratosis
(Redirected from Porokeratosis of Mibelli)
Porokeratosis is a group of rare, chronic, genetic disorders of keratinization characterized by atrophic patches surrounded by a distinctive hyperkeratotic ridge-like border called a cornoid lamella.
Types[edit | edit source]
There are several types of porokeratosis, including:
- Porokeratosis of Mibelli
- Disseminated superficial actinic porokeratosis
- Linear porokeratosis
- Punctate porokeratosis
- Porokeratosis palmaris et plantaris disseminata
Symptoms[edit | edit source]
The symptoms of porokeratosis vary depending on the type, but may include:
- Small, ring-like spots
- Red, scaly patches
- Itching or burning sensation
- Painful cracks on the palms of the hands and soles of the feet
Causes[edit | edit source]
The exact cause of porokeratosis is unknown, but it is believed to be genetic. It may also be triggered by exposure to sunlight, immune system disorders, or skin injuries.
Diagnosis[edit | edit source]
Porokeratosis is diagnosed through a physical examination and a skin biopsy. The biopsy can reveal the characteristic cornoid lamella, which is a diagnostic feature of porokeratosis.
Treatment[edit | edit source]
Treatment for porokeratosis may include:
- Topical creams and ointments
- Cryotherapy
- Laser therapy
- Dermabrasion
Prognosis[edit | edit source]
The prognosis for porokeratosis varies depending on the type and severity of the condition. Some forms of porokeratosis may increase the risk of skin cancer.
