Angiokeratoma of Fordyce response to long pulsed Nd:YAG laser treatment.

Angiokeratoma of Fordyce can be easily diagnosed by their typical erythra and cured by varied therapeutic methods including surgery, electrocoagulation, cryotherapy, or various laser systems. Which are the optimal therapeutic methods? There are no consentaneous opinions in the reported articles. We present our characteristic treatment with the application of long pulsed neodymium-dopedyttrium-aluminum-garne (lpNd:YAG) laser in the treatment of angiokeratoma of Fordyce. A 1064 nm lpNd:YAG laser (spot size: 5 mm/7 mm, energy:90-130 J/cm(2) , and pulse duration: 10-20 ms.) was used to treat the patient's lesions. The desirable clinical endpoint of the treatment was lesions shrunk and turned pallor immediately after the irradiation. The treatment interval was at least 8 weeks. Of the 11 patients, 9 of them were cured and 2 of them were improved. The mean treatment sessions were 2.2 times. None of them had a scar formation and any other side effects. All of them were satisfied with the treatment results. We conclude that angiokeratoma of Fordyce responded well to lpNd:YAG laser treatment. It provided a simple, rapid, and no bleeding treatment in treating Angiokeratoma of Fordyce.

Treatment of angiokeratoma of Mibelli alone or in combination with pulsed dye laser and long-pulsed Nd: YAG laser.

Treatment of angiokeratoma of Mibelli is usually challenging because of the location, the pathogenetic condition and the cosmetic requirements. We present our characteristic treatment with the application of pulsed dye laser PDL and lpNd:YAG laser. All of these lesions were treated by topical anesthesia with Emla. Combined dual PDL-lpNd:YAG (PDL: 595 nm, 5 mm/7 mm, 0.5 ms, 8-10 J/cm(2) ; lpNd:YAG: 3 mm/5 mm, 15 ms, 90-120 J/cm(2) ) treatment was used to treat lesions which with moderate to severe hyperkeratosis and hyperplasia. To the maculopapule ones, the energy density of lpNd:YAG might upgrade to 150 J/cm(2) . Singular PDL (595 nm, 5 mm/7 mm, 0.5 ms, 9-12 J/cm(2) ) treatment was used to treat lesions which with slight hyperkeratosis and hyperplasia. Continuous airflow cooling was always applied during the laser treatment. The treatment interval was 6-12 weeks. Of the 5 patients, 3 of them were cured and 2 of them were improved. All of them were satisfied with the cosmetic results. We recommended the combined dual PDL-lpNd:YAG laser in treating severe hyperkeratotic and hyperplastic angiokeratoma of Mibelli. It can aid in achieving a desirable outcome whilst also reducing the required treatment sessions. However, most patients felt painful during the operation and experienced a severe long term recovery time after operation.
