Prolactinoma and other head and neck tumors after scalp irradiation

Research output: Contribution to journalArticlepeer-review


Tumors of the thyroid and parathyroid glands may develop together or separately in patients who previously have been exposed to head and neck irradiation. Whether cranial irradiation confers an increased risk for pituitary adenoma remains unknown. We report the case of a 52-year-old woman who was treated during childhood for tinea capitis with scalp irradiation and later in life developed a prolactin-secreting tumor, a parathyroid adenoma, a benign thyroid lesion, and a basal cell carcinoma of the skin. She was treated successfully with bromocriptine and surgical removal of the parathyroid adenoma. Molecular analysis of the parathyroid tissue failed to demonstrate any abnormality of the multiple endocrine neoplasia Type 1 gene. This case report is the first to describe a prolactin-secreting tumor that developed in association with other endocrine neoplasia after head and neck irradiation. Our case suggests that multiple endocrine neoplasia may develop in a sporadic pattern after scalp irradiation.
