- In order to differentiate the causes of Cushing's syndrome; whether it is pituitary or adrenal-dependent, a high dose dexamethasone suppression test is usually performed but this does not always correlated with the imaging diagnosis. We report a case of bilateral macronodular adrenal hyperplasia, which was thought to be independent to adrenocorticotrophin (ACTH) stimulation. At first we thought it was pituitary-dependent Cushing's syndrome, due to its suppression by high dose dexamethasone. However, we found no abnormal findings on the brain sella magnetic resonance image (MRI). A significant finding, however, we found bilateral adrenal masses on the abdominal computed tomography (CT). We performed percutaneous selective adrenal venous sampling (PSAVS), and confirmed hypercortisolism of the left adrenal mass only. Therefore, we decided to remove the left adrenal gland to preserve the residual function of the right adrenal gland. After the left adrenalectomy, the patient became normotensive, and their buffalo hump disappeared, and her 24 hour urinary free cortisol level returned to normal.

Abstract

- Primary squamous cell carcinoma of the thyroid is rare, presenting much less than one percent of all primary thyroid malignancies. Most cases have been reported in elderly patients with a history of goiter. It is necessary to differentiate between primary squamous cell carcinoma and secondary involvement from other sites. Secondary involvement of the thyroid may be more amenable to palliation or cure. The treatment of choice in primary squamous cell carcinoma is radical surgery in resectable cases, but the squamous cell carcinoma behaves aggressively and carries a uniformly poor prognosis regardless of the treatment. We had an experience of a primary squamous cell carcinoma of the thyroid in two elderly patients. These patients presented a typical feature of a primary squamous cell carcinoma of the thyroid, which has been rarely reported in Korea.

Abstract

- Insuliin secreting tumor is 70% prevalent disease in female and predoadnant in forth and sixth deeade. The incidence of insulinoma is one case per 250,000 patient-years. Insulinoma in pregnancy was extremely rare, and the prevalence was not reported. The diagnosis of an insulinoma is depend on demonstration of hypoglycemia with high insulin and C-peptide levels. Immunoreactive insulin/plasma glucose ratio0.3 in particular support the diagnosis of an insulinoma. Fetal complication would be developed because of hypoglycemia. In approximately half of the cases reported, surgical exploration was done during pregrancy, the remainder were treated after delivery. Insulinoma poses serious diagnostic and therapeutic problems when she is pregnant. We experienced a case of insulinoma in pregnancy that represented Whipples triad and was treated by surgical intervention.
