Subungual precursor of hemangioma.

Abstract

Hemangioma in the first days of life is not three-dimensional and is poorly visible. It can present as a flat red patch and this is the aspect that most often refer parents, but sometimes the history and early physical examination put out an ischemic and / or cyanotic, round or segmental patch or an ischemic patch with coarse telangiectasias on the inside. It is likely, in agreement with its alleged pathogenesis, that the ischemic patch is the first event of hemangioma. Then it would be followed by neoangiogenesis with telangiectasias. The latter then flowing gives rise to a uniform red patch and finally to threedimensional hemangioma (1, 2). However, many precursors remain flat at the stage of telangiectasias inside an ischemic halo or red uniform patch. In our case the diagnosis of precursor was confirmed by the rosary dermoscopy finding of telangiectasias and by the presence of a classic precursor of hemangioma on the buttock.
