Epidermal naevi treated with pulsed erbium:YAG laser

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 5 2004
I. C. Pearson
Summary Epidermal naevi are common and can cause marked cosmetic disability. Ablative laser treatment may be successful in their removal, but may result in significant scarring. Surprisingly the erbium:YAG laser is rarely reported for this indication even though it produces minimal tissue damage. We report our experience using this laser to treat six patients with epidermal naevi. Patients (five female, one male; aged 4,41 years) underwent treatment with pulsed 2940 nm erbium:YAG laser at 0.4,0.45 J/cm2, 2 mm spot size at 4 pulses/s. All six patients had excellent cosmetic results at follow up ranging from 6 to 60 months. The favourable results were dependent on selection of cases with superficial or small, discrete lesions which could be ablated accurately. The erbium:YAG laser is therefore an effective treatment for relatively nonverrucous or papular epidermal naevi. [source]

Epibulbar complex choristoma and hemimegalencephaly in linear sebaceous naevus syndrome

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 8 2009
J. M. Park
Summary Epidermal naevus syndrome is a group of congenital syndromes comprising epidermal naevi associated with a variety of developmental abnormalities of the ocular, nervous, skeletal, cardiovascular and urogenital systems. We describe a case of an 8-month-old boy with a brown alopecic plaque on his face and scalp and a vascularized epibulbar mass involving the entire cornea, which had been present since birth. Histopathological examination identified sebaceous naevus in combination with complex choristoma. Magnetic resonance imaging of the brain showed hemimegalencephaly. [source]

Vascular anomalies in Proteus syndrome

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 3 2004
P. H. Hoeger
Summary Proteus syndrome (PS) is a complex hamartomatous disorder defined by local overgrowth (macrodactyly or hemihypertrophy), subcutaneous tumours and various bone, cutaneous and/or vascular anomalies (VA). VA are manifold in PS, but their prevalence is unknown so far. In order to further characterize PS, we studied the prevalence of VA in 22 PS patients presenting to our outpatient clinic and reviewed 100 PS patients previously reported between 1983 and 2001. The diagnosis of vascular abnormalities was made on clinical grounds and supported with imaging studies and/or histology in 12 and seven patients out of 22, respectively. Thirty-five VA were identified in 22/22 (100%) of our patients, and more than one type of VA were present in 10 of them. Vascular tumours, portwine stains (PWS), and venous anomalies (varicosities, prominent veins) were equally common. A total of 118 VA were previously reported in 70/100 (70%) PS patients; vascular hamartomas were more prevalent (56/118 = 47.5%), whilst PWS (21.2%) and venous anomalies (22.9%) were slightly less common than in our series, but there is the possibility of under-reporting. Unlike Klippel,Trenaunay syndrome, where VA are mostly confined to the hypertrophic limb, major arteriovenous anomalies are rare, and ,,similar to the other hamartomas and naevi observed in PS (pigmentary naevi, epidermal naevi, subcutaneous tumours, exostoses) , VA appear to be distributed at random sites on the body. We conclude that VA are among the most common findings in PS. Their varying type and distribution lend further support to the concept of somatic mosaicism. [source]
