Multiple pulmonary nodules with diffuse idiopathic pulmonary neuroendocrine cell hyperplasia and minute pulmonary meningothelial‐like nodules

Abstract

Key message A 78‐year‐old woman presented with multiple pulmonary nodules, mixed with solid and ground‐glass nodules. We pathologically confirmed that the multiple pulmonary nodules were a combination of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) and multiple pulmonary meningothelial‐like nodules (MPMNs). This is the first case report of concurrent DIPNECH and MPMNs.
