A Case of Ectopic ACTH Syndrome Caused by Thymic Carcinoid Tumor and Localized by PET / 대한내분비학회지

Ectopic ACTH syndrome is frequently caused by lung cancer and uncommonly by other tumors such as thymic carcinoid. For its treatment, early diagnosis and complete resection is irresponsible, but some cases are remained unlocalized in spite of all diagnostic modalities. Here we report a case of ectopic ACTH syndrome which was localized by PET but could not be localized by conventional technique. A tumor at thymic area was ACTH secreting thymic carcinoid which was operated but couldnt resect completly. Glucocorticoid hypersecretion was persisted with chemotherapy, radiotherapy, and ketoconazole treatment. Patient died of sepsis after 12 months of diagnosis.
