Pulmonary neuroendocrine tumor in a young male

Abstract

Pulmonary neuroendocrine tumor is a subtype of lung cancer, which does not have favorable outcome. The small-cell and large-cell variants of this cancer comprise 20% of all lung cancers. However, large-cell neuroendocrine tumor (LCNET) is not frequent and seen in about less than 3% of cases of lung cancer. Here, we describe a young nonsmoker male with the unholy triad of LCNET, newly diagnosed diabetes mellitus, and skin metastasis.
