A. Poikilodermatous plaque–like hemangioma
Histopathologic evaluation showed a band-like vascular proliferation in the upper dermis with no grenz zone. Vascular spaces were round and lined by a single layer of endothelial cells. No hemosiderin deposits were found with Perls Prussian blue stain. Vascular channel endothelial cells were positive for CD34 and CD31 but negative for D2-40. Based on histopathological findings, a diagnosis of poikilodermatous plaque–like hemangioma (PPH) was established. Considering the benign nature of the lesion, no treatment was performed.
Poikilodermatous plaque–like hemangioma is a newly described vascular proliferation. To our knowledge, only 17 cases of PPH have been reported. It is typically located on the lower extremity of older adult men and commonly described as a slowly growing, asymptomatic, solitary, erythematous-violaceous plaque with an overlying cigarette-paper wrinkling that gives an atrophic appearance.1,2
