Multiple Endocrine Neoplasm Syndrome (MEN)
Specific skin abnormalities have been recently identified in MEN-1 patients. These skin abnormalities include multiple angiofibromas, collagenomas, and lipomas.
The prognosis of NETs associated with the MEN-I syndrome has been controversial. In one study approximately half of the patients died as a direct result of a MEN I-specific illness that included islet cell tumors, peptic ulcer disease, hypercalcemia/uremia and carcinoid syndrome.
