ABSTRACT

BACKGROUND: Angiokeratoma of Fordyce (AF) represents dark red or blue-black papules with a scaly surface located on scrotum, labia majora, and penis. Though usually asymptomatic, bleeding after mechanical trauma and sexual intercourse may occur. AF should be differentiated from malignant melanoma, angiosarcoma, and other pigmented lesions. The treatment, usually asked from patients as the result of anxiety and social embarrassment, should be performed in a non-aggressive manner. OBJECTIVES: To determine the safety and effectiveness of 595-nm variable-pulse pulsed dye laser (VPPDL) with a Dynamic Cooling Device (DCD) in the treatment of AF. METHODS: Twenty-four patients (22 men and two women) aged 40.88 ± 12.48 years with AF were included in the retrospective study. Lesions located on scrotum, labia majora, and penis were treated with 595-nm VPPDL in the intervals of one to three months. Variable spot, fluence, and pulse-width parameters were used with and/or without DCD skin cooling. RESULTS: AF were successfully removed in all patients in one to seven (mean ± SD = 3.38 ± 2.16) treatment sessions with no permanent side effects or complications such as dyspigmentations or scarring. Recidives were observed in four patients after 0.5-1 year intervals. CONCLUSIONS: 595-nm VPPDL with DCD represents an efficient and safe method for the removal of multiple lesions of AF in genital localization.

ABSTRACT

Angiokeratomas are rare vascular mucocutaneous lesions characterized by small-vessel ectasias in the upper dermis with reactive epidermal changes. Angiokeratoma circumscriptum (AC) is the rarest among the five types in the current classification of angiokeratoma. We present a case of an extensive AC in 19-year-old women with Fitzpatrick skin type I of the left lower extremity, characterized by a significant morphological heterogeneity of the lesions, intermittent bleeding, and negative psychological impact. Histopathological examination after deep biopsy was consistent with that of angiokeratoma. The association with metabolic diseases (Fabry disease) was excluded by ophthalmological, biochemical, and genetic examinations. Nuclear magnetic resonance imaging has not detected deep vascular hyperplasia pathognomic for verrucous hemangioma. The combined treatment with 595-nm variable-pulse pulsed dye laser (VPPDL) and 755-nm long-pulse pulsed alexandrite laser (LPPAL) with dynamic cooling device led to significant removal of the pathological vascular tissue of AC. Only a slight degree of secondary reactions (dyspigmentations and texture changes) occurred. No recurrence was observed after postoperative interval of 9 months. We recommend VPPDL and LPPAL for the treatment of extensive AC.

ABSTRACT

BACKGROUND: Angiokeratoma of Fordyce is typically asymptomatic, blue-to-red papules with a scaly surface located on the scrotum, shaft of penis or labia majora. They can be treated with some locally destructive treatment modalities such as excision, electrocoagulation, cryotherapy and laser. OBJECTIVES: To compare the effects of the pulsed dye laser versus long pulsed Nd:YAG laser in the treatment of angiokeratoma of Fordyce. METHODS: Twenty tow patients with angiokeratoma of Fordyce were included in this study. All participants received three sessions of pulsed dye laser on the selected side or part of lesional area and long pulsed Nd:YAG laser on the other side or part of lesional area. Two dermatologists independently evaluated the photographs of the baseline and two-month follow-up after last session using a grade system in which treatment response was categorized into six grades. RESULTS: Both PDL and long pulsed Nd:YAG laser revealed statistically significant improvements in angiokeratoma of fordyce. Comparatively, there was a statistical difference between them (overall mean improvement with PDL, 61.8%, versus Nd:YAG, 77.63%; p < 0.005). CONCLUSIONS: Both PDL and 1064-nm Nd:YAG laser are effective and safe in the treatment of angiokeratoma of Fordyce with better response in Nd:YAG laser than pulsed dye laser.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: To retrospectively study the clinical efficacy of 595nm pulsed dye laser therapy for Mibelli angiokeratoma. METHODS: 50 cases of Mibelli angiokeratoma, from 10 to 41 year-old,were treated with the 595nm pulsed dye laser. The parameters were as follows: a wavelength of 595 nm, pulse duration of 10ms, spot size of 7 mm and energy fluency of 12.0-13.5 J/cm(2). The treatments were repeated at intervals of 4-6 weeks until the lesion was cleared, or the parents discontinued the treatment. Detailed demographics and the assessment of the degree of lesion clearance were statistically analyzed through SASS18.0. RESULTS: All the 50 patients were treated 1-4 times. The total rate of significant improvement was 80%, and the rate of full recovery was 30%. We failed to find statistical significance between genders, or the size and color of lesions, which might be due to limited sample size. The most common adverse effects after treatment were purpura and edema, which usually lasted for 12 h to several days. Temporary pigment alterations were not common. Other side effects such as scar or skin texture change were not observed. CONCLUSION: Our experience confirmed the clinical efficacy and safety of the 595 nm pulse dye laser in the treatment of Mibelli angiokeratoma.

ABSTRACT

Angiokeratomas are vascular malformations that are clinically or histologically verrucous, with superficial vessels just beneath the epidermis. Solitary angiokeratomas occur most commonly as a small, warty, black papule on the lower extremities. Various therapeutic methods, including laser, electrocoagulation, excision, and cryotherapy, may be used for their treatment. A 13-year-old girl presented to the laser clinic for the treatment of her lesions that were present for two months. A 1064-nm long-pulsed Nd:YAG (yttrium aluminium garnet) laser was used to treat the patient's lesions. We performed two laser treatment sessions at a 4-week interval. We saw the patient 1 month after the last treatment session and obtained successful cosmetically acceptable results. No recurrence was observed over a follow-up period of 3 months. Long-pulsed Nd:YAG laser is more effective for the treatment of hyperkeratotic angiokeratomas due to deeper skin penetration of laser. Long-pulsed Nd:YAG laser is an effective and safe therapeutic option for the treatment of solitary angiokeratomas.

ABSTRACT

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.

ABSTRACT

Angiokeratoma of the vulva is relatively rare with few cases reported in the literature. The lesions are usually asymptomatic, but clinical presentations can include bleeding and vulval pruritus. Treatments for symptomatic cases include surgical excision, cryotherapy and argon or carbon dioxide laser therapy. We present a case series of patients who have been successfully treated with pulsed dye laser therapy. This was performed in the outpatient setting without the need for local anaesthesia. All patients had resolution of their symptoms. This treatment modality to our knowledge has not been reported in the literature.

ABSTRACT

BACKGROUND: Angiokeratomas are typically asymptomatic, blue-to-red papules with a scaly surface located on the scrotum, shaft of penis, labia majora, inner thigh, or lower abdomen. The treatment of angiokeratomas may be necessary if they bleed and lead to patient anxiety. OBJECTIVE: To determine the safety and effectiveness of long-pulse 1,064 neodymium-doped yttrium aluminium garnet (Nd:YAG) laser for the treatment of angiokeratomas of Fordyce. MATERIALS AND METHODS: Ten consecutive patients with angiokeratoma of Fordyce were treated with long-pulse Nd:YAG laser in two to six sessions. The three authors independently assessed improvement of the lesion based on digital photographs taken before the treatment and 2 months after the end of the treatment. RESULTS: Significant (>75%, <100%) and moderate (>50%, <75%) improvement was seen in six and two patients, respectively. Complete improvement was achieved in one patient. Transient swelling, purpura, bleeding, and some pain in the treated area were noted in all patients as short-term side effects. There were no permanent side effects. CONCLUSION: The long-pulse Nd:YAG laser is a highly effective and safe treatment for angiokeratoma of Fordyce.

ABSTRACT

BACKGROUND: Angiokeratomas of Fordyce are typically asymptomatic vascular lesions characterized by blue-to-red papules with a scale surface, most often located on the scrotum. Although considered benign, the lesions may bleed, either spontaneously or secondary to rupture, leading to patient anxiety and social embarrassment. OBJECTIVE: The objective was to determine the safety and effectiveness of 585-nm pulsed dye laser for the treatment of angiokeratomas of Fordyce. METHODS: Twelve patients with Fitzpatrick skin type II to IV were treated for angiokeratomas of Fordyce with pulsed dye laser (5.5-8.0 J/cm(2)) in two to six sessions. Lesion clearance was evaluated by two specialists on the basis of digital photographs taken before the first treatment and 2 months after the last treatment. RESULTS: Seven patients had an excellent response (clearance rating 75%-100%) and five patients had a good response (clearance rating 50%-75%). Transient purpura and pain were present in all patients. Bleeding during treatment occurred in five patients. There were no permanent side effects. CONCLUSION: Pulsed dye laser is effective and safe for the treatment of angiokeratoma of Fordyce, with minimum side effects, providing an additional nonablative therapeutic option.

ABSTRACT

A 21-year-old patient with a six-year history of asymptomatic papular lesions on his scrotum is reported. The lesions were limited to one half of the scrotum and associated with subclinical varicocele on the same side. The clinical and histopathological findings were consistent with a diagnosis of angiokeratoma scroti. Increased venous pressure caused by the varicocele may have been responsible for the unilateral development of angiokeratoma in this patient.
