Summary

A 47-year-old patient with a large goiter and rib tumors was diagnosed with multiple endocrine neoplasia type 1 (MEN1). This rare genetic disorder involves tumors in the parathyroid, pituitary, and pancreas, with a family history supporting the diagnosis.

Area of Science:

  • Endocrinology
  • Oncology
  • Genetics

Background:

  • A 47-year-old patient presented with a large goiter and multiple rib tumors, initially suspected as metastatic thyroid cancer.
  • Laboratory tests revealed elevated ionized calcium and parathyroid hormone (PTH), prompting further investigation.

Observation:

  • The goiter was identified as parathyroid tumors due to high PTH levels.
  • Rib tumor biopsy confirmed brown tumors associated with primary hyperparathyroidism (PHP).
  • The patient also had prolactinoma and pancreatic gastrinoma, with a family history of PHP and prolactinoma.

Findings:

  • The patient was diagnosed with multiple endocrine neoplasia type 1 (MEN1).
  • MEN1 is a genetic disorder characterized by tumors in endocrine glands.

Implications:

  • This case highlights the importance of considering MEN1 in patients with seemingly unrelated endocrine tumors and skeletal lesions.
  • Early diagnosis and genetic counseling are crucial for affected families.
  • Understanding the genetic basis of MEN1 aids in developing targeted therapies.
