Abstract

A case of monocytic leukemia associated with active tuberculosis of pleura, pericardium, and lymph nodes is reported.

The criteria for the diagnosis of monocytic leukemia and the factors excluding a leukemoid reaction are presented.

The rarity of monocytic leukemia in contrast with the frequency of tuberculous infections and the rarity of active tuberculosis in the reported cases of monocytic leukemia indicate that the association of the two diseases is probably coincidental.

Grateful acknowledgment is due to Miss Anne Shiras and Mortimer Cohen, M.D., for the photo-micrographs.
