Diffuse in adultsidiopathic pulmonary neuroendocrine cell hyperplasia

Abstract

Diffuse Idiopathic Pulmonary NeuroEndocrine Cell Hyperplasia (DIPNECH) is an understudied rare disease that should be taken into account in the differential diagnosis of therapy-resistant bronchial obstruction combined with focal pulmonary lesions and mosaic attenuation on chest CT. The aim of this article is to discuss the aspects of clinical and morphological diagnosis, therapeutic options, prognosis assessment, and the need for follow-up using a clinical case as an example. The article describes a clinical case of DIPNECH in a 55-year-old woman, and also provides a brief review of the scientific literature on DIPNECH. DIPNECH is a rare disease that most often affects non-smoking women aged around 60 years. Themostfrequentclinicalmanifestationsarecough,dyspnea,stridor,andbroncho-obstructivesyndrome.Onlyhistologicalandimmunohistochemical assays can confirm the diagnosis. DIPNECH should be considered as part of the differential diagnosis in patients with prolonged cough, dyspnea of unclear genesis and changes on chest CT in the form of pulmonary focal lesions and mosaic attenuation. Conclusion. The presented clinical case shows the challenges and importance of timely diagnosis.
