“…The pathologic differential diagnosis of acquired elastotic hemangioma includes benign (such as acquired tufted hemangioma, angioma, and targetoid hemosiderotic hemangioma) and malignant (such as angiosarcoma, Dabska tumor, Kaposi sarcoma, and retiform hemangioendothelioma) vascular lesions (Table 7 ) [ 1 - 2 , 4 , 7 , 9 , 11 , 13 - 15 ]. The endothelial cells that line the vascular channels in acquired elastotic hemangioma can be plump and protrude into the vessel lumina in a hobnail pattern; therefore, other vascular proliferations with a hobnail pattern (such as angiosarcoma, Dabska tumor, retiform hemangioendothelioma, and targetoid hemosiderotic hemangioma) need to be considered and excluded.…”

“…Microscopically, similar to acquired elastotic hemangioma, there are dilated blood vessels in the superficial dermis. However, in contrast to acquired elastotic hemangioma, the walls of the vessels in cutaneous collagenous vasculopathy are thickened with hyaline material that is not only periodic acid-Schiff stain-positive but also shows Type IV collagen immunoreactivity and severe solar elastosis around and between the vessels is not a characteristic feature [ 13 - 14 ].…”

BackgroundAcquired elastotic hemangioma is a benign vascular proliferation that typically presents as an asymptomatic red plaque on a sun-exposed site of an adult.Material and MethodsThe PubMed database was used to search the following words: acquired, angioma, arm, basal, carcinoma, cell, elastosis, elastotic, exposed, forearm, hemangioma, solar, sun, and vascular. The relevant papers and reference cited generated by the search were reviewed. The features from a case series of 11 patients with acquired elastotic hemangioma are presented. In addition, a comprehensive review of the characteristics of this unique hemangioma—not only in our 11 patients but also in the previously reported 34 individuals with this lesion—is provided.ResultsAcquired elastotic hemangioma, reported in 45 patients (24 women and 21 men), typically appeared as an asymptomatic solitary red plaque in sun-exposed areas—most commonly the forearm--of adults aged 50 years or older. The pathology shows a proliferation of vascular channels—surrounded and intertwined by intense solar elastosis--in the upper dermis, located parallel to the overlying epidermis, and separated from it by a zone of normal-appearing superficial papillary dermis. There was extensive solar elastosis surrounding and between the new blood vessels; some of the endothelial cells protrude (in a hob-nail pattern) into the vessel lumen. The clinical differential diagnosis includes basal cell carcinoma and the pathologic differential diagnosis includes other benign, malignant, and reactive vascular lesions. Ultraviolet radiation may contribute to the pathogenesis of this hemangioma since it occurs on sun-exposed sites. There was no recurrence of the lesion following either excision or observation.ConclusionsThe possibility of acquired elastotic hemangioma should be considered by clinicians when they encounter an older individual with a new red plaque on a sun-exposed site that clinically appears to be a superficial basal cell carcinoma.
