title: Pulmonary T-cell lymphoma with pulmonary arterial hypertension.
abstract: We report on a 73-year-old man with systemic lymphadenopathy and chest computed tomography (CT) findings of bilateral diffuse ground-glass opacities and interlobular septal thickening. He also had pulmonary arterial hypertension (PAH). Several lymph node biopsies were attempted, without a definitive diagnosis. A thoracoscopic lung biopsy was performed, and the specimen was diagnosed as peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). Lymphoma cells had invaded lung vessels, resulting in PAH. We should include pulmonary lymphoma in the differential diagnosis of patients with PAH and chest CT findings of diffuse ground-glass opacities and interlobular septal thickening.
