Pituitary tumor cosecreting thyrotropin and prolactin causing hyperthyroidism--a case report.

We report a case of a pituitary tumor cosecreting thyrotropin and prolactin with clinical manifestation of thyrotoxicosis, which is a very rare clinical disorder. Octreotide therapy is effective in suppressing the secretion of thyrotropin, prolactin, and thyroid hormones, and by this, renders relief of symptoms and complications of thyrotoxicosis.
