Angioma serpiginosum

Angioma serpiginosum (angioma serpiginosum) is a rare disease of the skin, characterized by a rash of small red nodules, reminding angioma. First described by Hutchinson (J. Hutchinson), entitled "angioma infective". The etiology is unknown. Some authors include angioma serpiginosum to the nevi, others to capillaritis. Localizes the process often on the skin of the feet. The lesions grow on the periphery due to the extension of knots-satellites. As a result, Central regression appear larger, sometimes circle pockets with whitish atrophic centre. The disease begins in childhood or adolescence. The current is slow. Histologically in the dermis - proliferation of vascular endothelial compelaroma and papillary layer, the newly formed capillaries, small lymphoid infiltration, in the epidermis - the foci of edema, acanthosis, parakeratosis, an overall thinning of the epithelium. Treatment - freezing liquid carbon dioxide, diathermocoagulation (see).
