Venous lake é un hemanxioma senil dos beizos. Normalmente é unha protuberancia suave e azul causada por pequenas veas ensanchadas. Adoita aparecer só e non se sente duro ao tacto. Adoita ocorrer en partes da cara e das orellas que reciben moito sol. Un home de 46 anos entrou cun bulto azulado no beizo inferior que levaba 8 meses medrando. Comezou pequeno e foise facendo máis grande co paso do tempo. Dixo que non tiña feridos na zona. Non sufrira ningún sangrado sen motivo nin despois de feridas leves. Cando o médico o examinou, atoparon no seu beizo inferior unha única protuberancia azulada que era suave e fácil de comprimir. O médico tratouno con crioterapia usando nitróxeno líquido, conxelando a lesión durante 10 segundos de cada vez cunha pequena marxe ao seu redor. Eles facían este tratamento cada dúas semanas. Despois de 12 semanas, houbo algunha mellora.
A venous lake, sometimes referred to as senile hemangioma of the lips is usually a solitary, non-indurated, soft, compressible, blue papule occurring due to dilatation of venules. It is commonly found on sun-exposed surfaces of the face and ears. A 46 year old male patient presented with an 8 month history of a single, painless, bluish swelling over the lower lip which began as a pea sized lesion and gradually increased to the present size. Patient strongly denied any history of trauma at the site. No history of bleeding spontaneously or following minimal trauma could be elicited. On physical examination, a single, violaceous, soft, compressible, non-indurated, non-pulsatile papule was present on the lower lip. Patient was treated with cryotherapy with application of liquid nitrogen by dipstick method with one 10-second freeze-thaw cycle with a 1-mm margin. This was done at biweekly intervals. Some improvement was obtained following 12 weeks of therapy.
