Introduction:
Multiple endocrine neoplasias (MEN) are rare inherited syndromes. MEN type 2 syndromes occur in 1:30000 individuals, and are reported in approximately 500-1000 families worldwide, the most frequent being MEN 2A (80%), followed by familial medullary thyroid carcinoma (15%) and MEN 2B (5%) (Marx and Wells, 2011; Dumitrache, 2012).
Case:
The patient, a 20-years old with MEN 2A syndrome, which has been manifested by bilateral pheochromocytoma and medullary thyroid carcinoma. It was a familial form, having first degree relatives (mother) with pheochromocytoma. The patient underwent laparoscopic adrenalectomy on her left in 2015, laparoscopic adrenalectomy on the right in 2019 and total thyroidectomy in 2020 year. The postoperative evolution of this patient is favorable. She is satisfied with the received treatment and is being supervised by an endocrinologist, undergoing hormone replacement therapy.
Conclusions:
The case demonstrates the importance of the radical approach to MEN 2A syndrome from both a therapeutic and surgical point of view. If a pheochromocytoma is detected, adrenalectomy should be performed before thyroidectomy or other surgery to avoid intraoperative catecholamine release. Laparoscopy is the choice of approach in surgical treatment. Limitations only arise because of technical difficulties or tumor size.
Insights
Multiple endocrine neoplasias type 2A (MEN 2A) is a rare inherited syndrome. This case highlights the importance of radical surgical management, prioritizing adrenalectomy before thyroidectomy for MEN 2A patients.
Area of Science:
- Endocrinology
- Genetics
- Surgical Oncology
Background:
- Multiple endocrine neoplasias (MEN) are rare inherited syndromes affecting approximately 1 in 30,000 individuals.
- MEN type 2 syndromes, including MEN 2A, familial medullary thyroid carcinoma, and MEN 2B, are characterized by specific genetic mutations.
- MEN 2A is the most frequent subtype, accounting for 80% of cases.
