Sub-Category:
Multiple Endocrine Neoplasia (MEN) Syndromes
Number of Conditions: 6
MEN Type 1 - Hypercalcemia
Specialty: Diabetes and Endocrinology
Category: Rare Endocrine Disorders
Sub-category: Multiple Endocrine Neoplasia (MEN) Syndromes
Symptoms:
fatigue; kidney stones; bone pain; abdominal pain
Root Cause:
Genetic mutation in the MEN1 gene leads to tumor formation in endocrine glands (parathyroid, pituitary, pancreas).
How it's Diagnosed: videos
Genetic testing for MEN1 mutation. Hormonal blood tests (calcium, PTH, prolactin, growth hormone, insulin). Imaging studies (MRI or CT scans of the pituitary, pancreas, and parathyroid glands).
Treatment:
Surgical removal of tumors (e.g., parathyroidectomy, pituitary surgery). Medical management for hormone overproduction (e.g., somatostatin analogs for pancreatic tumors). Regular monitoring for tumor progression.
Medications:
Calcimimetics (e.g., cinacalcet ) for hyperparathyroidism. Dopamine agonists (e.g., cabergoline , bromocriptine ) for prolactinomas. Somatostatin analogs (e.g., octreotide , lanreotide ) for pancreatic neuroendocrine tumors. Proton pump inhibitors (e.g., omeprazole ) for gastrinomas.
Prevalence:
How common the health condition is within a specific population.
Approximately 1 in 30,000 individuals worldwide.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Family history of MEN1 syndrome, autosomal dominant inheritance.
Prognosis:
The expected outcome or course of the condition over time.
Generally good with early detection and treatment, though tumor recurrence is possible; life expectancy may be reduced without management.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Recurrent or metastatic tumors. Severe hypercalcemia leading to kidney damage. Hormonal crises, such as insulinoma-induced hypoglycemia.
MEN Type 1 - Pituitary Adenoma
Specialty: Diabetes and Endocrinology
Category: Rare Endocrine Disorders
Sub-category: Multiple Endocrine Neoplasia (MEN) Syndromes

headaches; vision problems; hormonal imbalances

MEN Type 1 - Pancreatic Neuroendocrine Tumor
Specialty: Diabetes and Endocrinology
Category: Rare Endocrine Disorders

MEN Type 2 - Medullary Thyroid Cancer
Specialty: Diabetes and Endocrinology
Category: Rare Endocrine Disorders
Sub-category: Multiple Endocrine Neoplasia (MEN) Syndromes
Symptoms:
neck lump; difficulty swallowing; hoarseness
Root Cause:
Mutation in the RET proto-oncogene causes tumor formation in thyroid C-cells, adrenal medulla, and parathyroid glands.
How it's Diagnosed: videos
Genetic testing for RET mutations. Serum calcitonin and carcinoembryonic antigen (CEA) levels for medullary thyroid cancer. Plasma or urine metanephrines for pheochromocytoma. Imaging (ultrasound, CT, or MRI) for tumors.
Treatment:
Total thyroidectomy for medullary thyroid cancer (often prophylactic in high-risk patients). Adrenalectomy for pheochromocytoma. Medical management for blood pressure control in pheochromocytoma (alpha and beta-blockers). Regular follow-ups for new tumor formation.
Medications:
Alpha-blockers (e.g., phenoxybenzamine ) to control blood pressure in pheochromocytoma. Beta-blockers (e.g., propranolol ) used after alpha-blockade to stabilize cardiovascular symptoms. Thyroid hormone replacement (e.g., levothyroxine ) post-thyroidectomy. Calcimimetics (e.g., cinacalcet ) for hyperparathyroidism.
Prevalence:
How common the health condition is within a specific population.
Approximately 1 in 35,000 individuals worldwide.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Family history of MEN2 syndrome, autosomal dominant inheritance.
Prognosis:
The expected outcome or course of the condition over time.
Excellent with early prophylactic thyroidectomy; pheochromocytoma and parathyroid tumors require ongoing management for optimal outcomes.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Untreated pheochromocytoma can cause hypertensive crises and cardiovascular complications. Advanced medullary thyroid cancer may lead to metastasis. Persistent hyperparathyroidism can result in long-term kidney damage.
