General Discussion. Hairy cell leukemia (HCL) is a rare type of blood cancer characterized by abnormal changes in white blood cells known as B lymphocytes. The bone marrow creates too many of these defective cells, known as hairy cells because of the thin hair-like projections found on their surface.
Lung carcinoma is the leading cause of malignant pleural effusions. Malignant effusions are observed in 7 to 15% of all bronchogenic carcinomas at some time during the course of the illness (2, 3, 13, 169). Effusions occur with all histologic types, most frequently with adenocarcinoma (12, 87).pproximately 10% of malignant pleural effusions are due to lymphoma. According to reports in the early 1940s, in Hodgkin's disease, pleural effusions develop in 16% of patients, pleural thickening in 7%; the figures were, respectively, 15 and 11% in non-Hodgkin's lymphoma and 2 and 4% in leukemia (11).
