POMC and lung carcinoid tumor: A case of ACTH-secreting lung carcinoid was managed after thoracic surgery, ketoconazole and aminoglutethimide, and bilateral adrenalectomy failures, with octreotide treatment at dosage of 20 mg/month for three years and, subsequently, CAB at dosage of 3.5 mg/week for 8 years, with the achievement of a marked reduction of ACTH levels, depigmentation and disappearance of the tumour mass detected by yearly lung computed tomography [39].
