title: [Type II multiple endocrine neoplasms (MEN IIB): an unusual cause of constipation. A plea for early thyroidectomy].
abstract: We present a 5 year old girl who was diagnosed to have multiple endocrine neoplasia syndrome type IIB (MEN IIB). She presented with serious constipation and had the distinct features of MEN IIB. 100% of the patients with MEN IIB develop medullary thyreoïd carcinoma (MTC). MTC in MEN IIB is known to behave in a very aggressive way. Microscopically MTC was already present in this patient despite of normal calcitonin stimulation tests. Accordingly we plead for a more radical management relating to thyreoïdectomy in MEN IIB.
