Ectopic Neuroendocrine Carcinoma: An Occult Source of ACTH Abstract #2885

Introduction: About 250 cases of ectopic ACTH-producing neuroendocrine carcinoma (ACTH-NEC) have been reported; however metastatic ACTH-NEC of unknown primary is very rare. Usually are characterized by having a large cell, small cell, poorly differentiated or anaplastic cell, and Ki-67 index between 40-90%.
Aim(s): Exhibit the challenge that represents the workup and treatment of occult ectopic ACTH-NEC.
Materials and methods: We present a case of a 67-year-old male with hypokalemic alkalosis. He complains asthenia, adynamia, hyporexia, fatigue, weakness, weight loss of 5 kg, polydipsia, diabetes mellitus of 3 weeks of evolution, absence of a Cushing phenotype. He was a smoker.

#2233 Potential Effects of Ketoconazole on ACTH-Producing and Non-ACTH-Producing Neuroendocrine Tumors
Introduction: Prolonged biochemical remission after treatment with steroidogenesis inhibitors has been described in patients with Cushing’s syndrome due to ectopic adrenocorticotropin hormone (ACTH) production. Some studies have suggested antiproliferative and apoptotic effect of ketoconazole in human cancer cells.
