Paraneoplastic cushing’s syndrome: A diagnostic and therapeutic challenge: A case report and literature review

Ectopic Cushing syndrome (ECS) is difficult to diagnose and has a poor prognosis. We report a case of a 44-year-old male who was admitted for clinical suspicion of Cushing's syndrome. The investigations confirmed the diagnosis of ECS. No tumor was detected in preliminary imaging tests. Then, the octreoscan showed a fixation in a suspect lung node in the middle lobe. The patient was treated initially with medical drugs, he underwent a right middle lobectomy, and yet histopathology did not reveal any nodule. However, the outcome was the healing of our patient. We reviewed published articles to access new diagnostic techniques or advantages in the treatment regimen and a prognosis of ECS.
