• Carcinoid tumors of the thymus gland have occasionally been associated with endocrine hyperfunction. A case of thymic carcinoid was initially observed as Cushing's syndrome and was also associated with marked hyperpigmentation. While the hyperpigmentation may be related to the excessively high levels of corticotropin, it is also possible that thymic carcinoids could produce melanocyte-stimulating hormone—like (or β-lipotropin) material.
