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

Abstract

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.
