Porokeratosis can develop into skin cancer. If a lump or sore develops within a porokeratosis lesion you get it checked immediately by a doctor or skin specialist.

Porokeratosis has several names that are associated with it. Examples of these variants are basal cell papilloma, senile keratosis, seborrheic verruca, senile warts, barnacles, and brown warts. A cornoid lamella is a sure manifestation of porokeratosis, which is a clonal keratinization disorder. A cornoid lamella is composed of closely stacked parakeratotic cells that extend throughout the stratum corneum.

Currently, there are five variations of porokeratosis that are known. These are linear porokeratosis, porokeratosis palmaris et plantaris disseminate, disseminated superficial actinic porokeratosis, punctate porokeratosis, and classic porokeratosis of Mibelli. Disseminated superficial actinic porokeratosis is rather common in the United States. The other variants of porokeratosis are more rare.

The people who are the most prone to porokeratosis are fair-skinned individuals. In fact, the disorder is not often seen among darker-skinned individuals.

The two variants, orokeratosis palmaris et plantaris disseminate as well as 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. Meanwhile, classic porokeratosis of Mibelli usually begins to develop starting from childhood. Between 30-40, adults are typically prone to disseminated superficial actinic porokeratosis.

What are the things that can cause porokeratosis? Porokeratosis has been said to be caused by too much exposure to the sun, immunosuppression, ultraviolet light exposure, therapeutic phototherapy, radiation therapy, as well as heredity. A study showed that ten percent of renal transplant patients later developed the skin condition.

Patients of porokeratosis have to make sure that they avoid any unnecessary exposure to the sun. It is advisable that they wear protective clothing as well as use sunblock.

Porokeratosis treatment can be done through many ways. Treatment for this disorder must be individualized. Doctors have to think about certain factors such as the lesion’s anatomical location, the size of the lesion, risk of malignancy, the aesthetic and functional issues, as well as the patient’s preference.

For numerous patients, sun protection as well as the usage of emollients might be all that is required for relief. Patients should also keep a look out for any indications of malignant degeneration.

Porokeratosis treatment can also take the form of surgical care. Surgery is necessary for lesions that have become malignant over time. The most appropriate surgical modality for malignant degeneration is excision. Last but not the least, porokeratosis can also be treated using curettage, diamond fraise dermabrasion, laser therapy, electrodesiccation, as well as cryotherapy and Ag3derm Cream – a topical treatment you can apply at home.
