Erythema annulare centrifugum as the presenting sign of CD 30 positive anaplastic large cell lymphoma--association with disease activity.

Erythema annulare centrifugum is a figurate erythema that has been associated with many different entities. A case of erythema annulare centrifugum related to non-Hodgkin's lymphoma in a 38-year-old woman is described in this case report. Response of the lymphoma to a combination chemotherapy was accompanied by disappearance of skin lesions. When therapy was discontinued, both disorders recurred, and both responded to reinstitution of a different chemotherapy regimen. To our knowledge, this case is the first reported association of erythema annulare centrifugum and non-Hodgkin's lymphoma in the medical literature.
