Multiple endocrine neoplasia type 1--presenting with impotence.
Singapore Medical Journal
|June 1, 1990
Summary
This case highlights an unusual presentation of multiple endocrine neoplasia type 1 (MEN-1) in a man with impotence and hyperprolactinemia. The patient also had hypergastrinemia and a pituitary microadenoma, suggesting a rare endocrine disorder.
Area of Science:
- Endocrinology
- Oncology
- Nephrology
Background:
- Multiple Endocrine Neoplasia type 1 (MEN-1) is a genetic disorder characterized by tumors in endocrine glands.
- Common manifestations include parathyroid, pituitary, and pancreatic tumors.
- Impotence and hyperprolactinemia are less common presenting symptoms.
Observation:
- A 35-year-old male presented with a 4-year history of impotence.
- Past medical history significant for hypercalcemia, renal calculi, and hyperparathyroidism.
- Endocrine workup revealed hyperprolactinemia, hypergastrinemia, and increased basal acid output.
Findings:
- Magnetic resonance imaging (MRI) indicated a pituitary microadenoma.
- Computed tomography (CT) scan revealed a bulky pancreas, suggestive of a gastrin-secreting islet cell tumor.
- This constellation of findings points to an atypical presentation of MEN-1.
Implications:
- This case underscores the importance of considering MEN-1 in patients with seemingly unrelated endocrine and gastrointestinal issues.
- Highlights the diagnostic challenge posed by unusual symptom combinations in MEN-1.
- Emphasizes the need for comprehensive endocrine evaluation in complex cases.
