A mixed functional microadenoma and ganglioneuroma of the pituitary fossa

Abstract

✓ The authors describe a case of a mixed prolactin- and somatotropin-secreting pituitary adenoma and ganglioneuroma of the pituitary fossa in a patient with galactorrhea, hyperprolactinemia, and headaches. Histological and electron microscopic findings were typical for each element of the tumor, but the finding of a ganglioneuroma within the pituitary fossa is unusual; even more unusual was its proximity to an apparently unrelated tumor in the same location. The clinical, radiological, endocrinological, and pathological findings are discussed.
