Introduction
Graves' disease with functioning nodules is referred to as Marine-Lenhart Syndrome. Only 2.7% of the patients with Graves’disease have concomitant functioning nodules.1 Thyroid scintigraphy often definitively confirms the diagnosis. However, in addition to a hyperfunctioning (i.e. "hot") nodule, the thyroid scan may reveal isofunctioning (i.e. "warm"), and or a nonfuntioning (i.e. "cold") nodule as compared to the normal surrounding thyroid. Since hyperfuntioning nodules rarely harbor malignancy, if one is found that corresponds to the nodule in question, no cytologic evaluation is usually necessary.2 Conversely, the majority of all nonfunctioning nodules may be benign or less frequently malignant, …

Medullary thyroid carcinoma (MTC) accounts for 15% of thyroid cancers. It arises in the C-cells of the thyroid, and is often metastatic at presentation. Approximately 75% of MTC cases are sporadic. Heritable MTC is subdivided into three categories: MEN2A, familial medullary thyroid carcinoma (FMTC), and MEN2B. Determination of the particular mutation may guide the timing of prophylactic total thyroidectomy in family members who carry the mutation.

ACTH-dependent Cushing’s syndrome results from excessive ACTH secretion from a pituitary gland adenoma (Cushing’s disease) in 80% of cases. Much less commonly, ectopic ACTH production occurs outside the pituitary gland, with the majority of those cases caused by bronchial carcinoids. A small number are due to excessive ACTH secretion by a pheochromocytoma.
