CECENARRO, LA et al. An Infrequent Presentation of Esthesioneuroblastoma with Ectopic ACTH Syndrome. Rev. argent. endocrinol. metab. [online]. 2014, vol.51, n.4, pp.192-196. ISSN 1851-3034.

Introduction: Esthesioneuroblastoma is a tumor originating from the neuroblasts in the neuroectodermal olfactory epithelium. It accounts for 3 % to 6 % of nasal tumors. Adrenocorticotropic hormone (ACTH) ectopic secretion is the cause for 10 % to 20 % of ACTH-dependent Cushing Syndrome cases. Esthesioneuroblastoma constitutes a rare cause of ectopic ACTH secretion. Case presentation: A 63 year-old female patient presented with dizziness, nausea, muscle weakness, and rhinorrhea of two-year duration under long-term treatment with topical corticosteroids. On physical examination, she showed typical Cushingoid phenotype. Brain MRI revealed an expanding lesion in the ethmoid area involving the orbit and the cranial base. Sub­maxillary metastasis was also detected. Lab tests confirmed ACTH values 20-fold above normal. The patient underwent treatment for hypercortisolism prior to surgery. Surgical treatment was prompted by the need to decompress the tumor. Comment: Esthesioneuroblastoma is a rare tumor. Although approximately 1,000 cases have been published in the last 20 years, only eleven of them were due to ACTH secretion. Treatment is complex and requires an interdisciplinary team.
