title: Paraneoplastic Cushing's syndrome associated to locally advanced thymic carcinoid tumor.
abstract: BACKGROUND
  Thymic carcinoid is a frequent cause of Cushing's syndrome due to ectopic adrenocorticotropin secretion. Histology and immunohistochemistry allow differential diagnosis from other epithelial thymic tumors, such as thymomas and thymic carcinomas. The term used to name this tumor is confusing, since it is a malignant neuroendocrine neoplasm, and therapeutic approaches need to bear that in mind.
  
  
  METHODS
  Unlike most cases of thymic carcinoid associated to Cushing's syndrome that had distant metastases at diagnosis, we report a 50-year-old male who presented with Cushing's syndrome and was diagnosed with thymic carcinoid without distant metastases. Multimodal treatment with surgery, radiotherapy and chemotherapy (cisplatin plus etoposide) induced a complete clinical and biochemical remission lasting for 46 months.
