title: Cytophagic panniculitis and B cell lymphoma.
abstract: A 43-year-old woman had multiple, painful nodules of the legs and edema of both lower extremities for 3 years and leukopenia for 8 years. This histologic findings of lobular histiocytic panniculitis with "beanbag" cells were typical of cytophagic panniculitis. This case is unique in that B cell lymphoma developed in the spleen, as verified by immunoperoxidase staining, and demonstrates that the disease not only may be a progressive disease per se but also may be associated with nonhistiocytic malignancy.
