#111 Atypical lung carcinoid tumor metastatic to endocrine glands and bone marrow

Introduction: Bronchopulmonary neuroendocrine tumors (BP-NETs) comprise 20% of all lung cancers. Typical low grade carcinoid tumors (TC) represent the majority of BP-carcinoids. Intermediate grade atypical carcinoid tumors (AC) are less often encountered but more aggressive. Although metastatic dissemination to mediastinal lymph nodes, liver, skeleton and central nervous system (CNS) is common, involvement of the endocrine glands has rarely been reported.
