Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare pulmonary condition, characterized by diffuse proliferation of neuroendocrine cells in the respiratory epithelium. DIPNECH lesions are less than 5 mm in size and are limited to the basement membrane with no invasion. There is limited information regarding epidemiology, natural history of disease progression, or the management of this rare entity. We present the experience of a center with extensive expertise in neuroendocrine disease.. A cohort of patients (N = 13) with DIPNECH treated and followed at our institution was identified. We describe the our approach to their care, our disease management and also provide a review of DIPNECH pathophysiology.. Our patient cohort consisted of twelve females and one male with a mean age of 63 years at the time of diagnosis. Dyspnea on exertion and dry cough were the most common presenting symptoms. Two patients were under surveillance without treatment; three patients were treated with a short-acting somatostatin analog; three patients were treated with azithromycin alone; four were treated with a combination of long-acting monthly somatostatin analogs and azithromycin; one patient received a combination of long-acting somatostatin analog and everolimus. Five patients had concomitant bronchial carcinoids.. DIPNECH is a rare pathology that can profoundly affect a patient's quality of life. Paroxysmal coughing episodes can be difficult to treat. Our limited single center experience shows encouraging response to use of somatostatin analogs, azithromycin, and everolimus in the management of debilitating DIPNECH associated symptoms.

Primary neuroendocrine tumors of the thymus are extremely rare. In patients with advanced disease, tumor growth control, and sometimes also syndrome control are the main goals of systemic therapy. Unfortunately, no standard therapies are available in clinical practice; therefore, clinical studies are strongly recommended. Axitinib (AXI) is a tyrosine kinase inhibitor, currently under investigation in an international phase II/III trial including thymic neuroendocrine tumors. Over the past 5 months, the entire world has been facing a devastating medical emergency brought about by a pandemic due to a novel coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which emerged in Wuhan, China, in late 2019. Since then, health professionals have been expending all their efforts on trying to provide the best available treatments for patients involved. Patients with cancer, especially those with thoracic involvement, are at higher risk of coronavirus disease 19 (COVID-19) and its complications because of their immunosuppressive status caused by the cancer and the anticancer therapies. As it remains unclear how to optimally manage such patients, we wished to report our experience with a patient with a metastatic neuroendocrine tumor of the thymus infected with SARS-CoV-2 in the hope that it may provide some insights and reflections on the management of cancer patients during this challenging time in our history.
