Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) and multiple pulmonary epithelioid hemangioendothelioma (PEH): a case report

Summary: We report a case of a 76-year-old female with multiple lung nodules with history of cough. The lower left lobectomy showed four nodules that were described as pulmonary epithelioid hemangioendothelioma (PEH). In the remaining parenchyma of the lobe, multiple nests of neuroendocrine cells were observed and the diagnosis was diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH). Introduction: Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare condition, with under 100 cases described in literature [1, 2]. Pulmonary epithelioid hemangioendothelioma (PEH) is a…
