Porokeratosis of Mibelli: Successful Treatment with Cryosurgery

Porokeratosis of Mibelli, a disorder of keratinization, should be treated because of the possibility of development of malignant epithelial tumors on the porokeratotic lesions. Liquid nitrogen cryosurgery is considered to be particularly useful in the treatment of precancerous and benign skin lesions. We aimed to evaluate the efficiency of this method in the treatment of porokeratosis of Mibelli. Eight patients with 20 porokeratotic lesions were treated with spray cryosurgery. Each lesion was frozen for 30 seconds with a spray tip after the keratotic borders were removed conically by sharp dissection. Eighteen of the 20 lesions were healed successfully with slight atrophy in one session. One more session was necessary for the other two lesions. Liquid nitrogen cryosurgery may be considered superior to other destructive methods in the treatment of porokeratosis of Mibelli, with advantages such as simplicity, high cure rates, low cost, short treatment period, and few complications.

Therapeutic Evaluation of Intralesional 5% 5-Fluorouracil in Condyloma Acuminata

Condyloma acumianata is one of the most common virally transmitted diseases. Its prevalence has increased many fold throughout the world. Because all the currently available treatments yield low cure rates with side effects, the search for a new alternative continues. Topically, 5-fluorouracil (5-FU) has been in used for many years to treat various skin diseases. When applied topically in condyloma acuminata, 5-FU results in low cure rates with high recurrences. Therefore, intralesional 5% 5-FU is being evaluated to determine its therapeutic efficacy in condyloma acuminata.

Linear porokeratosis: successful treatment with diamond fraise dermabrasion

A patient with linear porokeratosis was successfully treated with diamond fraise dermabrasion. Follow-up evaluation revealed an excellent cosmetic result with adequate repigmentation, no scarring, and no recurrence of lesions. Long-term follow-up will be necessary to determine whether dermabrasion treatment of linear porokeratosis provides adequate prophylaxis against the subsequent development of malignancy.

Linear porokeratosis: treatment with the carbon dioxide laser

A patient with a lifelong linear porokeratosis was treated with a carbon dioxide laser. The laser was successful in removing the patient's hyperkeratotic plantar lesion. No recurrence has been noted in a 6-month follow-up visit. This report demonstrates another dermatologic condition that can be treated successfully with the CO2 laser.

Carbon dioxide laser treatment of porokeratosis of Mibelli

Porokeratosis of Mibelli, a disorder of keratinization, has in the past been difficult to treat, especially in its more extensive form. The carbon dioxide laser was used in the treatment of a patient with this disorder. The response was very favorable. Microscopic pathological investigation after treatment revealed no residual evidence of porokeratosis in the areas treated with the carbon dioxide laser. Thus, obliteration of this disease process using the carbon dioxide laser shows potential for future use.

Porokeratosis (Mibelli): treatment with topical 5-fluorouracil

The case history of a patient with a solitary classic porokeratosis (Mibelli) on the hand is described. The lesion cleared without scarring with the use of topical 5-fluorouracil until a strong dermatitis was elicited, thus avoiding surgery and attendant restriction of function. No sign of recurrence developed in the following 2 years. The potential for malignant change in porokeratosis (Mibelli) and its resistance to topical treatment as documented in the literature are also reviewed.
