Capillary hemangioma is a benign tumor comprised of endothelial cells, common in childhood, which frequently disappears on its own. Port-wine stains are vascular malformations caused by capillary dilatation, initially characterized by macules with colors ranging from rose to violaceous red. Present at birth, they are usually permanent, and can thicken and cause deformities. Many treatments have been proposed: cryotherapy, surgery, corticotherapy, radiotherapy, and laser therapy. However, such treatments involve technical difficulties, high costs, complications, or unaesthetic results.This study proposes a new, easy to perform and cost effective association of techniques: percutaneous cerclage and radiofrequency electrosurgery for the treatment of hypertrophic lesions of vascular origin.

Pyogenic granuloma or lobular capillary hemangioma is a benign skin and mucous membranes lesion whose etiology is not yet explained. The authors report an atypical and exuberant clinical case of this benign dermatologic condition, clinically simulating malignancy.

Angioma serpiginosum is a rare and benign vascular ectasia that clinically arises as small red or purple dots, with serpiginous configuration. Controlled light pulses or intense pulsed light is the light source that emits high energy light within the continuous waves spectrum from 500nm to 1,200nm. Among its characteristics is the indication for the treatment of vascular lesions, which is the oxyhemoglobin chromophore’s pigment. This paper describes a case of a 12-year-old patient with angioma serpiginosum on the right arm that receded after 6 intense pulsed light sessions.

Vascular anomalies correspond to a broad spectrum of changes that fall into two main groups: 1) vascular tumors, which represent proliferative lesions, and 2) vascular malformations, caused by ectasia in vessels, whether capillary, venous or lymphatic.This article reviews the main vascular anomalies observed in dermatological practice, their main classifications and available treatments, focusing on the use of lasers and intense pulsed light to lighten cutaneous vascular lesions, especially those resulting from malformations.

Cryosurgery is a technique widely known and used among dermatologists. Intralesional application is already used to treat keloids and has the advantage of restricting the zone of action of low temperatures of liquid nitrogen. The use of contact cryosurgery in vascular lesions is well reported in the literature, but there are no intralesional technique publications on these types of lesions. Here, we report two cases, one of port-wine stain hamartomas in a 61-year-old patient and another of a cherry angioma in a 70-year-old patient, safely and satisfactorily treated with intralesional cryosurgery.

O queratoacantoma (QA), apesar de frequente na prática diária, é um tumor que gera questionamentos. O aspecto mais intrigante associa-se à sua posição no limite entre malignidade e benignidade. A abordagem do tumor, bem como sua classificação, é controversa. Na definição da conduta, é importante levar em conta o potencial de transformação para carcinoma espinocelular. Desse modo, a excisão cirúrgica é a terapia de escolha, sempre que possível. Algumas situações merecem atenção adicional, como a imunossupressão associada. Neste artigo, relatamos um caso de QA gigante em um paciente com síndrome da imunodeficiência adquirida tratado com cirurgia micrográfica de Mohs.

Congenital vascular lesions can be subdivided into tumors and malformations. Hemangiomas are benign vascular tumors resulting from the abnormal proliferation of endothelial cells, whereas port-wine stains are vascular malformations of a possible autosomal dominant inheritance. To date, there are no studies associating the use of intense pulsed light and CO2 laser as a therapeutic form for these pathologies. We present a series of 10 cases of vascular injuries treated with the combination of these forms of irradiation. This combined therapy can be effective in reducing the thickness of the lesions or in attenuating the color.
