RESUMO

Se presenta el caso de un recién nacido a término que presenta en rodilla derecha masa redondeada, indolora, violácea, no friable ni ulcerada. Se realiza al nacimiento ecografía Doppler compatible con anomalía vascular. La Resonancia Magnética (RM) confirma tumoración anterior en rodilla derecha, isointensa en T2 con escasas estructuras tubulares serpinginosas, que corresponden con vasos sanguíneos. Presenta venas varicosas de drenaje a la Safena Mayor (SM) en cara anterointerna del muslo. Se decidió actitud expectante constatando reducción progresiva del tamaño del hemangioma. Al año de vida, refiere que en ocasiones presenta un bultoma a nivel inguinal derecho que se corresponde en ecografía doppler con cayado de la SM dilatado e incompetente, en probable relación con hiperaflujo de las varicosidades. Se realiza seguimiento en consulta, comprobando involución completa a los dos años, con atrofia cutánea residual en cara anteroexterna de rodilla y vascularización colateral que no aumenta con valsalva. Se trata de un hemangioma congénito rápidamente involutivo (RICH). Según la clasificación ISSVA, es un tumor vascular benigno que involuciona persistiendo leve hiperpigmentación y atrofia cutánea.

We present the case of a newborn at term with a rounded, painless, violaceous, non-friable and non-ulcerated mass in the right knee. Doppler ultrasound was performed at birth, compatible with vascular anomaly. Magnetic Resonance Imaging (MRI) confirms an anterior tumor in the right knee, isointense in T2 with few serpinginous tubular structures, corresponding to blood vessels. It presents varicose veins draining to the greater saphenous vein (MS) in the anterointernal aspect of the thigh. A wait-and-see approach was decided and a progressive reduction in the size of the hemangioma was observed. At one year of life, the patient reported that she occasionally presented a bulge at the right inguinal level that corresponded on Doppler ultrasound with a dilated and incompetent arch of the greater saphenous vein, probably related to hyperflow of varicose veins. The patient was followed up in consultation and complete involution was observed after two years, with residual cutaneous atrophy on the anteroexternal aspect of the knee and collateral vascularization that did not increase with valsalva. It is a rapidly involutive congenital hemangioma (RICH). According to the ISSVA classification, it is a benign vascular tumor that involves with persistent mild hyperpigmentation and cutaneous atrophy. (provided by Infomedic International)
