Infections in patients with chronic adult T-cell leukemia/lymphoma: case report and review.

Adult T-cell leukemia/lymphoma (ATLL) is caused by the human T-cell lymphotropic virus type I (HTLV-I). ATLL is classified into the smoldering, chronic, lymphoma, and acute subtypes. We describe a North American woman with chronic ATLL who presented with pneumonia caused by Pneumocystis carinii, Cryptococcus neoformans, Mycoplasma pneumoniae, and Mycobacterium avium complex. Although opportunistic infections have been documented in patients with ATLL, there are few case reports detailing infectious complications in patients with chronic ATLL.
