Description
We describe the clinical manifestations of a multiple endocrine neoplasia, type IIb, in a 32 year old woman, admitted to a general hospital with intestinal sub-occlusion. The phenotype associated with bilateral pheochromocytomas show us the diagnosis, but the unsolved problem is the high levels of calcitonin, without macroscopic evidence of tumor relapse.
