A rare presentation of Ectopic Cushing Syndrome in a patient with small cell lung cancer

Ectopic Cushing’s syndrome (ECS) is a rare para neoplastic syndrome that occurs in patients with small cell lung cancer (SCLC). Because of the aggressive nature of the syndrome and its atypical features, ECS in small-cell lung cancer is difficult to diagnose and has a poor prognosis. We report a case of a 53-year-old male patient who presented with severe proximal muscle weakness in all4 limbs, and loss of appetite. He had no chest symptoms. The patient was eventually diagnosed with stage IV primary small-cell lung cancer with ECS and survived only one week following diagnosis. We have conducted a review of relevant published articles.
