Skin manifestations of POEMS and AESOP syndrome in the same patient revealing plasma cell dyscrasia

POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin signs) and AESOP (adenopathy and extensive skin patch overlying a plasmacytoma) syndromes are rare paraneoplastic conditions due to an underlying plasma cell dyscrasia. We report a 70‐year‐old patient with the rare coexistence of POEMS and AESOP syndromes and in whom skin signs, that differ both clinically and histologically, were the clues to the diagnosis of a plasma cell disorder. Vascular endothelial growth factor‐A overexpression seems to be the common pathogenetic link of the different clinicopathological presentations of the skin lesions.
