海绵状血管瘤伴晕皮炎1例OA

We report a case of the meyerson phenomenon around cavernous hemangioma.A 23-year-old male presented with a dark purplish red nodule on the back for over 20 years,and pruritic annular erythema and papules with clear boundaries around the nodule for 1 day.Dermato-logical examination revealed a dark purplish red nodule about 0.7 cm in diameter on the back,en-circled by a 1 cm diameter erythema with papules.Dermoscopic examination showed that several small purplish red cavities with clear boundaries and irregularly distributed dotted blood vessels on the skin lesion under the red background.The histopathology showed that the lesion was covered with squamous epithelium.Large irregular lumens,and sinusoids of different sizes contained red blood cells and fibrin in the superficial and deep dermis.The sinusoids were lined with a single layer of endothelial cells.The patient was diagnosed with the meyerson phenomenon around cav-ernous hemangioma.After surgical resection,the eczema-like dermatitis subsided.But hemangio-ma reoccurred without discomfort after more than 1 month.The patient is in follow-up.
