    Department of Dermatology, Medical College of Wisconsin, Milwaukee, Wisconsin.
    Hobnail hemangioma (HH), initially termed targetoid hemosiderotic hemangioma, is a rare, often solitary lesion classically characterized by a central brown or violaceous papulonodule surrounded at times by an ecchymotic halo. This lesion is typically found on the trunk or limbs of children or young to middle-aged adults. Numerous case reports have found HHs to have a reproducible histologic appearance. Read More

    Targetoid hemosiderotic hemangioma: a case report of multiple asymptomatic lesions.
    Cutis 2013 Aug;92(2):91-3
    700 W Jefferson St, Kirksville, MO 63501, USA.
    Targetoid hemosiderotic hemangioma (THH) is a benign vascular tumor characterized by a central violaceous papule with a clear periphery bordered by an ecchymotic ring. Originally coined by its characteristic halo appearance with hemosiderin deposits, not all THHs have this classic halo or hemosiderin composition. We report a unique case of THH in which the patient presented with multiple lesions with no prior trauma. Read More

    Cutaneous vascular proliferation. Part II. Hyperplasias and benign neoplasms.
    J Am Acad Dermatol 1997 Dec;37(6):887-919; quiz 920-2
    Department of Dermatology, Fundación Jiménez Díaz, Universidad Autónoma, Madrid, Spain.
    This second part of our review about vascular proliferations summarizes the clinicopathologic features of the cutaneous vascular hyperplasias and benign neoplasms. Hyperplasias comprise a heterogeneous group of vascular proliferations that eventually show a tendency to regression. Angiolymphoid hyperplasia with eosinophilia is included within the group of hyperplasias because of its historical denomination and its reactive nature, probably as a consequence of an arteriovenous shunt, although usually the lesions do not regress.

    Lymphangioma-like variant of Kaposi's sarcoma: clinicopathologic study of seven cases with review of the literature.
    Am J Dermatopathol 1997 Feb;19(1):16-22
    Institute of Histopathology and Anatomical Pathology, University of Sassari, Italy.
    The clinical and pathological features of seven cases of lymphangioma-like Kaposi's sarcoma (KS) are reported. As with the other subtypes of KS, the lymphangioma-like variant occurs more often in men aged 59-80 years. Clinically, the lesion appears intermingled with the classical forms of KS, but a "bulla-like" appearance recognized in seven of 13 cases has been considered as a clinical hallmark of this variant.

    Hobnail hemangioma.
    Dermatology 1995 ;191(2):154-6
    Department of Pathology, Hospital del Niño Jesús, Madrid, Spain.
    We report a case of hobnail hemangioma presenting as a congenital 2-mm brownish papule on the face of an 11-year-old girl. Hobnail hemangiomas have recently been characterized as a group, and they are related to the so-called targetoid hemosiderotic hemangiomas. Immunohistochemical data (positivity for factor VIII-related antigen, CD-34 and CD-31) support a vascular origin. Read More

    [Targetoid hemosiderotic hemangioma].
    Ann Dermatol Venereol 1995 ;122(3):111-4
    Service d'Anatomie Pathologique, Hôpital Pasteur, Nice.
    Introduction: Targetoid hemosiderotic hemangioma (THH) is a new vascular disorder, rarely reported. The lesion presents as violaceous papule surrounded by an ecchymotic ring usually measuring less than 1 cm in diameter. Epithelioid endothelial cells with a hobnail appearance, vascular papillary projections and hemosiderin deposits are the histological hallmarks of this entity. Read More

    [Target-like hemosiderotic hemangioma. Further differential diagnosis of Kaposi sarcoma].
    Hautarzt 1994 Jan;45(1):34-7
    Universitäts-Hautklinik Heidelberg.
    Targetoid haemosiderotic haemangioma (THH) can be differentiated from other angiomatous lesions by the characteristic findings on clinical and histological examination. Clinically the solitary lesion is suggestive of a melanocytic or angiomatous origin, surrounded by a haemorrhagic halo in the acute phase. Histological findings vary depending on the duration of the alteration. Read More

    Targetoid hemosiderotic hemangioma.
    J Cutan Pathol 1990 Aug;17(4):233-5
