What You Should Know About Porokeratosis

Porokeratosis has several names that are associated with it. These include senile keratosis, senile warts, seborrheic verruca, barnacles, brown warts, and basal cell papilloma. As a clonal keratinization disorder, porokeratosis becomes visible as a cornoid lamella. A cornoid lamella is composed of closely stacked parakeratotic cells that extend throughout the stratum corneum.

There are five clinical porokeratosis variants that are very well-known. These are linear porokeratosis, porokeratosis palmaris et plantaris disseminate, disseminated superficial actinic porokeratosis, punctate porokeratosis, and classic porokeratosis of Mibelli. Among the five variants, disseminated superficial actinic porokeratosis is fairly widespread in the United States. The other variants of porokeratosis are more rare.

Fair-skinned people are the most at risk to porokeratosis. Porokeratosis is actually rather uncommon among darker-skinned people.

The two types, orokeratosis palmaris et plantaris disseminate and classic porokeratosis of Mibelli, affect twice as many men than women. Disseminated superficial actinic porokeratosis happens 3 times as much in women compared with men. On the other hand, linear porokeratosis occurs in men just as much as it does in women.

With regards to the statistics when it comes to age, porokeratosis palmaris et plantaris disseminate and linear porokeratosis can appear at any age. Classic porokeratosis of Mibelli, however, typically develops at an early age (childhood). Between 30-40, adults are usually prone to disseminated superficial actinic porokeratosis.

What causes porokeratosis? It can be caused by any of the following: immunosuppression, therapeutic phototherapy or photochemotherapy for psoriasis, sun exposure, genetic inheritance, radiation therapy, and ultraviolet light exposure. There has also been a study that revealed that of all renal transplant patients, 10 percent later on had porokeratosis.

Patients of porokeratosis have to make sure that they avoid any unnecessary exposure to the sun. They must remember to don protective clothing against the sunlight as well as put on sunblock.

There are many ways that can be part of porokeratosis treatment. It must be individualized according to several factors. Factors to consider for individualized treatment include the size of the lesion, risk of malignancy, the lesion’s anatomical location, the functional as well as aesthetic concerns, and the patient’s preference.

For many people affected by porokeratosis, appropriate protection from the sun and the regular use of emollients may be all that is necessary. The patient must also be watchful for signs of malignant degeneration.

Another method for porokeratosis treatment is surgical care. Surgery is necessary for lesions that have become malignant over time. Excision, on the other hand, is the way best used to deal with malignant degeneration. Other ways used to treat for porokeratosis include laser therapy, diamond fraise dermabrasion, electrodesiccation, cryotherapy, as well as curettage.
