title: Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) in a patient with hypereosinophilic syndrome showing multiple nodules on chest computed tomography.
abstract: Hypereosinophilic syndrome (HES) encompasses both myeloproliferative and lymphoproliferative diseases. We encountered a rare case of lymphocytic HES followed by malignant T cell lymphoma, who was diagnosed as eosinophilic pneumonia upon the first visit. During the clinical course, the transition of the chest CT findings from bilateral multifocal ground-glass opacities and consolidations to bilateral scattered multiple small nodules was impressive and suggestive. Given the increased risk of developing T-cell lymphoma, patients with HES (especially lymphocytic-HES) should be monitored on a regular basis to detect this complication as early as possible.
