Malignant prolactinoma, a rare invasive pituitary tumor, is diagnosed by metastasis, not histology. Bromocriptine offers palliative care for these aggressive adenomas.

Area of Science:

  • Endocrinology
  • Oncology
  • Neurosurgery

Background:

  • Malignant prolactinoma is a rare, aggressive tumor arising from pituitary adenomas.
  • Distinguishing malignant from benign prolactinoma is challenging, often requiring evidence of metastasis.

Observation:

  • This study presents two new cases of malignant prolactinoma and reviews existing literature.
  • Cases often develop from known, particularly invasive, pituitary adenomas.

Findings:

  • Diagnosis of malignant prolactinoma relies on detecting metastasis, not solely on histological examination.
  • Bromocriptine demonstrates utility as a palliative treatment option.

Implications:

  • Understanding the diagnostic criteria and treatment options for malignant prolactinoma is crucial for patient management.
