Abstract
To describe extreme hyperprolactinemia originating from a pituitary adenoma in the wall of an ovarian dermoid. This is a description of an unusual case and a review of ectopic prolactin production. Ectopic production of prolactin is a rare condition that has been reported in isolated organ system pathology including ovaries. An ovarian dermoid is a benign neoplasm that has the potential for active unregulated endocrine function. Hyperprolactinemia can result from functioning lactotrophs found in ovarian dermoids and can lead to clinical sequelae. Definitive treatment of the condition requires surgical removal of the functioning endocrine tissue. Extreme hyperprolactinemia caused by a pituitary tumor located within a dermoid has not been reported before. We present a case of profound hyperprolactinemia originating from a pituitary adenoma found in the wall of an ovarian dermoid and give a broad overview of the condition and literature. Ectopic prolactin production should always be considered in symptomatic patients found to have elevated serum levels and no findings on brain imaging.
