Summary
This case study details a rare instance of multiple endocrine neoplasia type 1 (MEN1) presenting with a thymoma. The patient had concurrent gastrinoma, hyperparathyroidism, and an invasive thymoma, highlighting complex endocrine system interactions.
Area of Science:
- Endocrinology
- Oncology
- Rare Diseases
Background:
- Multiple Endocrine Neoplasia type 1 (MEN1) is a genetic disorder predisposing individuals to tumors in endocrine glands.
- Thymoma is a rare tumor originating in the thymus gland, often associated with autoimmune conditions.
Observation:
- A 57-year-old woman presented with symptoms of chronic duodenal ulcer and hypoglycemia.
- Investigations revealed pancreatic nodules, hypercalcemia, elevated gastrin levels, and an anterior mediastinal tumor.
- Preoperative diagnosis considered MEN1 with thymic carcinoid or thymoma.
Findings:
- The patient was diagnosed with MEN1, gastrinoma, hyperparathyroidism, and an invasive thymoma.
- Surgical intervention included concomitant thymectomy and parathyroidectomy.
- Histopathological analysis confirmed invasive thymoma.
Implications:
- This case underscores the importance of considering thymoma in MEN1 patients with mediastinal masses.
- Concurrent surgical management of endocrine tumors and thymoma can be feasible.
- Further research into the association between MEN1 and thymoma is warranted.
