Targetoid hemosiderotic hemangioma - Case report.

Kakizaki P, Valente NY, Paiva DL, Dantas FL, Gonçalves SV - An Bras Dermatol (2014 Nov-Dec)

Bottom Line: Targetoid Hemosiderotic Hemangioma, also known as Hobnail Hemangioma, is a lesion of vascular origin, probably lymphatic.Histopathologically, there is a biphasic pattern, with dilated vessels in the superficial dermis and pseudoangiosarcomatous pattern in the deep dermis, and endothelial cells with hobnail morphology.A simple excision is curative.

ABSTRACT
Targetoid Hemosiderotic Hemangioma, also known as Hobnail Hemangioma, is a lesion of vascular origin, probably lymphatic. The most common clinical feature is a solitary violaceous papule surrounded by a pale, thin area and a peripheral ecchymotic ring, simulating a target. Histopathologically, there is a biphasic pattern, with dilated vessels in the superficial dermis and pseudoangiosarcomatous pattern in the deep dermis, and endothelial cells with hobnail morphology. A simple excision is curative. We report a rare case of Targetoid Hemosiderotic Hemangioma.

f01: Violaceous, targetoid lesion consisting of a papular center surrounded by a paler,intermediate area and a peripheral purpuric halo on the upper back

Mentions: A 29-year-old male patient, born and residing in São Paulo-SP, presentedviolaceous, targetoid lesions consisting of a papular center surrounded by a paler,intermediate area and a peripheral purpuric halo. The lesion measured about 3 x 2 cm,was located on the upper back and had been present for 1 year (Figure 1). An incisional biopsy of the lesion showed angiomatousproliferation in the dermis and nuclear atypia, suggesting a diagnosis of angiokeratomaor Kaposi's sarcoma (Figures 2-6). The diagnosis was made after review of the slide,which showed epidermis with mild acanthosis. In the superficial dermis, dilated vesselproliferation had an aspect compatible with lymphatic capillary, sometimes showingendothelial cells with a hobnail aspect, giving prominence to the lumens. More deeply,vascular spaces become sometimes slit-like, appearing to dissect through collagenbundles. Presence of extravasated erythrocytes and hemosiderin deposits at the peripheryof the lesion. These findings, correlated with the clinical feature of targetoid lesion,allowed us to make the diagnosis of THH. The patient opted for a total removal of thelesion.
