Angioma en penacho (angioblastoma de Nakagawa). Consideraciones sobre la influencia de las hormonas sexuales femeninas en su evolución Tufted angioma. Consideration of the influence of female sexual hormones in its evolution

ABSTRACT Summary Tufted angioma is a benign slow progressing tumour that affects mainly children and young adults. It appears frequently before the age of 5 years. Its clinical appearence is as macule, papule, plaque or nodule; skin coloured, erithematous, bluish, and localizes usually in the face, neck, shoulders or upper part of the chest. Local hyperhidrosis, infiltration, increased temperature, telangiectasies and petechias may be observed. Other important clini- cal manifestations include pruritus and/or pain. Tufts of capilar vessels in the dermis or subcutis is the main histological feature. The light of these ves- sels is reduced, rounded by colagen, giving the appearence of cannon bullet. Two female patients with diagnosis of tufted angioma whose evolution were significantly affected by hormonal changing situations are reported. We theorize about the possible rol of female sexual hormones in the growing of this angioblastoma.
