Abstract
ANDREOLI, ML. Targetoid hemosiderotic hemangioma: A case report. Rev. argent. dermatol. [online]. 2016, vol.97, n.4, pp.62-89. ISSN 1851-300X.
Vascular anomalies have been classified by Mulliken and Glowacki in 1982 and recently modified this classification by the International Society for the Study of Vascular Anomalies (ISSVA) today accepted worldwide, dividing vascular tumors and malformations. Within the same we find a variety of tumors from the more frequent as infantile hemangiomas, to the others with lower frequency, integrating clinical and genetic syndromes. Targetoid haemosiderotic haemangioma (THH), also known as hobnail haemangioma, is within that classification in the group of "other" vascular tumors due to their low frequency. It was described by Santa Cruz and Aronberg in 1988. It`s a benign vascular proliferation that arises most commonly on the trunk and limbs of young or middle-aged adults. The aim is to present a case of hobnail haemangioma, which is constantly being revised now a days, deepen of the knowledge of vascular tumors, their classification and immunohistochemical markers, review national and international literature and determine under what classification we would include this entity. The purpose is also to conduct a thorough analysis of the differential diagnosis of this disease, taking into account the clinical practice and demonstrate how new diagnostic technologies help us to approach it´s origin.
