Rarely occurrance of two diffuse idiopathic neuroendocrine cell hyperplasia cases

Abstract

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare disease which needs a long time for diagnosis and usually defined by case reports and small series. We reported two cases, one with 67 and the other with 66-years-old, both of them were female. They presented with long-lasting complaints of cough and shortness of breath. Computed tomography of patients showed multiple nodules on the basis of lungs, and additionally, mosaic perfusion was seen in the first case. Tissue samples were taken with video-assisted thoracic surgery, and the patients were diagnosed with DIPNECH by immunohistochemical examination. We wanted to emphasize the importance of DIPNECH which is a rare clinical entity causing chronic respiratory symptoms which should be considered in differential diagnosis of multiple pulmonary nodules.
