Abstract
|
|
|
|
Acroangiodermatitis is a rare, self-limiting, angioproliferative disorder associated with congenital vascular malformations or acquired venous insufficiency. The clinical features of acroangiodermatitis are notably similar to those of Kaposi sarcoma, making it difficult to differentiate between the two diseases. A 57-year-old male patient presented with multiple violaceous to black, crusted, indurated plaques with ill-defined margins on both swollen lower legs. A venous Doppler study of the bilateral lower limbs was unremarkable. A histopathological examination showed a hyperplastic epidermis, a prominent proliferation of small dilated vessels lined by plump endothelial cells in the dermis, hemosiderin deposits, and lymphocytic infiltrate around vessels. Immunohistochemical analysis showed CD31＋ and podoplanin＋ staining in endothelial cells.
