Abstract:
About 5% of patients with SCLC have the ectopic production of ACTH. Ectopic ACTH production of SCLC is suspected when patients of SCLC have unexplained metabolic alkalosis and hypokalemia. Most patients lack the classic feature of Cushing's syndrome. According to the recent report, they have poor prognosis, which median survival is less than 4 months and associated with a high rate of complication during chemotherapy. Also a case of paraneoplastic CRH production with SCLC can mimic the ectopic ACTH syndrome hut it can be distinguished by immunohistochemistry or direct measurement of serum CRH level. We report here a case of small cell lung cancer associated with Cushing's syndrome of ectopic ACTH production. That is immunohistochemically provened by staining with ACTH.
