    Abstract:
    A proportion of small cell carcinoma of the uterine cervix is known to secrete a neuroendocrine substance. However, cases presenting Cushing's syndrome due to ACTH secreted from a cervical small cell carcinoma are extremely rare. Here, we report a case of small cell carcinoma of the uterine cervix that ectopically secreted ACTH and presented Cushing's syndrome. A 42-year-old woman was initially admitted to the endocrine unit for investigation of ectopic ACTH syndrome. Serum cortisol and plasma ACTH levels were elevated with no diurnal variation. After gynecologic examination, her original disease was found to be a stage IIb cervical small cell carcinoma. She underwent a radical hysterectomy and pelvic lymphadenectomy. The entire tumor was excised and post-TNM classification was T2bN1M0. Immunohistochemically, tumor cells stained strongly for ACTH and chromogranin. Electronmicroscopic pictures showed typical neurosecretory granules. Although plasma ACTH returned to normal after surgery, liver metastasis appeared during the course of postoperative irradiation. She died 9 months after operation in spite of vigorous systemic chemotherapy.
