Efectividad del propranolol en el tratamiento de malformaciones vasculares cutáneas / Effectiveness of propranolol in treatment of cutaneous vascular malformations

Se realizó un estudio cuasi-experimental de series temporales para evaluar la efectividad del propranolol en el tratamiento de malformaciones vasculares cutáneas en 48 pacientes que asistieron a la consulta del Servicio de Dermatología del Hospital Central Universitario Dr. Antonio María Pineda durante el período febrero-julio 2018. Los resultados muestran que existen diferencias estadísticamente significativas (p <0.05; p0,0001) antes y después del primer mes de tratamiento con propranolol, las cuales se mantiene hasta los seis meses, con respecto al tamaño, color, consistencia y temperatura. Se espera que los resultados sirvan para proponer el uso de propranolol como una opción terapéutica no invasiva en el tratamiento de las malformaciones vasculares cutáneas(AU)

A quasi-experimental study of time series was carried out to evaluate the effectiveness of propranolol in the treatment of cutaneous vascular malformations in 48 patients attending the Dermatology Service of the Hospital Central Universitario Dr. Antonio Maria Pineda during the period February - July 2018. The results show that there are statistically significant differences (p <0.05; p0,0001) before and after treatment with propranolol starting one month post-treatment which are kept until six months, related to size, color, consistency and temperature of lesions. We hope that these results will encourage the use of propranolol as a non-invasive therapeutic option in the treatment of cutaneous vascular malformations(AU)

Vasculopatia livedoide tratada com rivaroxabana / Livedoid vasculopathy treated with rivaroxaban

A vasculopatia livedoide é uma doença rara caracterizada pela oclusão da microvasculatura da derme, originando lesões maculosas que, posteriormente, podem evoluir para úlceras e cicatrizes atróficas. Como um fenômeno vaso-oclusivo, o tratamento geralmente é realizado com antiplaquetários e fibrinolíticos. O presente relato descreve o caso de uma paciente refratária à terapia convencional, que obteve regressão da doença utilizando a rivaroxabana, um fármaco inibidor seletivo do fator Xa. (AU)

Livedoid vasculopathy is a rare disease characterized by occlusion of the dermis microvasculature, leading to spotted lesions that can later develop into ulcers and atrophic scars. As a vaso- occlusive phenomenon, treatment is usually performed with antiplatelet and fibrinolytic agents. The present report describes the case of a female patient refractory to conventional therapy who presented disease remission using rivaroxaban, a selective factor Xa inhibitor drug. (AU)

Reporte de caso de granuloma facial, una vasculitis cutánea infrecuente / A case report of granuloma faciale, an uncommon cutaneous vasculitis

El granuloma facial es una dermatosis benigna poco frecuente de etiología desconocida, generalmente asintomática, caracterizada por inflamación crónica y localizada habitualmente en zonas fotoexpuestas de la cara, con un patrón histológico característico. Si bien la respuesta al tratamiento es variable, existen múltiples opciones terapéuticas que han reportado ser efectivas en algunos pacientes. Entre estas alternativas se incluyen tratamientos sistémicos con corticoides y dapsona o tratamientos intralesionales con corticoides, crioterapia e inhibidores de calcineurina tópicos. Describimos el caso de un paciente adulto con una placa eritemato violácea asintomática en mejilla derecha, de crecimiento lentamente progresivo de dos años de evolución, clínica e histopatológicamente compatible con granuloma facial y respuesta favorable a corticoides intralesionales.

Granuloma faciale is an uncommon benign dermatosis, with unknown etiology, usually asymptomatic, characterized by chronic inflammation localized in sun-exposed areas of the face with a characteristic histological pattern. Although response to treatment is variable, there are multiple therapeutic alternatives that have been reported to be effective in some patients, including systemic treatments with steroids and dapsone or also topical treatments like intralesional corticosteroid, cryotherapy and calcineurin inhibitors, such as tacrolimus. We present the case of an adult patient with an asymptomatic erythematous-violet plaque on the right cheek, with progressive slow growth over two years, clinically and histologically and pathologically compatible with a facial granuloma. The patient responded well to intralesional corticosteroids.

Vasculopatía livedoide: reporte de dos casos / Livedoid vasculopathy: a two case report

Vasculopatía livedoide es una enfermedad poco frecuente que se presenta principalmente en mujeres de edad media de la vida, antes de los cuarenta años. Es llamado también atrofia blanca, livedo reticular con ulceración de verano, vasculitis hialinizante segmentaria, o PURPLE (úlceras purpúricas dolorosas con patrón reticular de extremidades inferiores). Generalmente afecta los tobillos y se exacerba en primavera y verano. Su etiología es aún desconocida, pero se puede clasificar en formas primarias (sin ninguna patología asociada) y secundarias, ambos con un componente trombótico. A continuación se describen dos casos de vasculopatía livedoide: una mujer de 22 años con úlcera en pierna izquierda y púrpura retiforme en ambas extremidades. El estudio demostró que el cuadro estaba asociado o síndrome antifosfolípidos. El segundo caso es de una mujer de 47 años con uno vasculopatía livedoide secundaria o lupus eritematoso sistémico.

Livedoid vasculitis is a rare disease that occurs mainly in women under 40 years of age. It has also be ennamed atrofia blanche, hyaline segmentary vasculitis or PURPLE (purpuric ulcers with reticular pattem in low legs). It usually affects ankles and has an exacerbation during Spring and Summer seasons. It has an unknown etiology, and it has been classified as primary (or idiopathic) or secondary (associated to another disease). We describe two cases of livedoid vasculopathy: the first case is o 22-year-old women with ulcers and retiform purpura associated to antiphospholipid syndrome. The second case is o 47-year-old women with livedoid vasculopathy associated to systemic lupus erythematosus.

Indomethacin for recurrent cutaneous necrotizing eosinophilic vasculitis.

Recurrent cutaneous necrotizing eosinophilic vasculitis (RCNEV) is a rare disease characterized by clinical features of pruritic purpuric papules and angioedema. Skin biopsies revealed the eosinophil-predominate necrotizing vasculitis affecting small dermal vessels. Systemic corticosteroid is a very effective treatment. There are many side effects associated with systemic corticosteroid therapy. The authors report a case of RCNEVsuccessfully treated with indomethacin. To the authors'knowledge, there has been no reported case of RCNEV treated with indomethacin.

Fênomeno de Raynaud grave associado a terapia com interferon-beta para esclerose múltipla: relato de caso / Severe Raynaud's phenomenon associated with interferon-beta therapy for multiple sclerosis: case report

Interferon-B (IFN-beta) é usado no tratamento de esclerose múltipla (EM). Descrevemos o caso de uma mulher com EM que apresentou fenômeno de Raynaud grave, livedo reticular e necrose digital duas semanas após tratamento com IFN-beta. Os sintomas melhoraram após suspensão do IFN-beta e início de anticoagulação associada a ciclofosfamida e corticóide. Fenômeno de Raynaud é um efeito colateral provável da terapia com IFN-beta para EM.
