An Unusual Case of a Rare Disease: PJP Infection in Adult T-Cell Lymphoma

Abstract

Adult T-cell leukemia-lymphoma (ATL) is a rare human T-lymphotropic virus, type I (HTLV-1)-associated disease occurring in 0.5 cases per 100,000 people in the United States . Common presenting clinical features include: generalized lymphadenopathy, hypercalcemia, lytic bone lesions, and skin. Respiratory manifestations are less common (1). A retrospective study (2) found that 60% of patients with ATL had abnormal chest CT scan findings. Ground glass attenuation (GGO) were the most common abnormality. Pathologically, the chest CT scan abnormalities were correlated with lymphocytic infiltration along the interstitium and alveoli. Here we present a case of an atypical presentation of ATL.
