Group 5 pulmonary hypertension (PH) encompasses diverse diseases, with a few cases linking it to T-cell large granular lymphocytic (LGL) leukemia. We report a case of a 76-year-old woman, diagnosed with LGL leukemia and concomitant PH, treated with oral triple pulmonary arterial hypertension (PAH) therapy. ⋯ At that time, deterioration in PH prompted the addition of selexipag, resulting in sustained clinical improvement for an additional 5 years. This case exemplifies the potential for sustained benefits of PAH therapy in leukemia-associated PH and highlights the need for continued research on the mechanistic relationship between LGL leukemia and PH, with the hope of identifying new management strategies.

A 14-year-old Chinese boy presented with a 7-year history of exertional dyspnea and reduced exercise tolerance. His perinatal and family histories were unremarkable. He was short and underweight for his age since childhood but had normal intellectual development. ⋯ He improved after symptomatic treatment and was discharged, without taking any oral medication afterwards. However, his dyspnea and exercise tolerance worsened gradually. This patient was referred to Children's Hospital affiliated with Zhengzhou University for further investigation and management.
