ResumoVarious dermatoses have been described associated with rheumatoid arthritis. Recently, a specific cutaneous lesion termed “intravascular histiocytosis” has been proposed as a new entity among these dermatoses. We report the case of a 50-year-old woman with rheumatoid arthritis for about 10 years who developed erythematous patches on the extensor surface of lower extremities. Histopathologically, the lesions showed intraluminal proliferation of CD68-positive histiocytes in vessels lined with endothelial cells expressing D2-40, a selective marker for lymphatic endothelium.
