title: Lymphocytosis in a patient with malignant fibrous histiocytoma.
abstract: Malignant fibrous histiocytoma is an uncommon soft-tissue sarcoma. Patients with malignant fibrous histiocytoma may present with unusual clinical findings and an apparent association with malignant hematopoietic disease has been reported. We describe a patient in whom a diagnosis of chronic lymphocytic leukemia was made simultaneously with discovery of a large, retroperitoneal malignant fibrous histiocytoma. Following surgical debulking of the tumor, the patient's blood and bone marrow findings returned to normal.
