A rare adenocarcinoma with poor prognosis, arising from the adenohypophysial cells of the anterior lobe of the pituitary gland or pre-existing adenomas. The majority are hormonally functioning neoplasms, usually producing prolactin or ACTH. The diagnosis is based on the presence of metastases. Syndromes associated with pituitary gland carcinomas include hyperprolactinemia, Cushing disease, and acromegaly.
Features include always present findings: Pituitary carcinoma; and very common findings: Increased circulating prolactin concentration, Headache, Increased circulating ACTH level, and Pituitary prolactin cell adenoma and others. 22 total HPO annotations.
Organ System | Phenotype Count | Example Features |
