Missed Diagnosis of Multiple Endocrine Neoplasia Type 2 B.

Multiple endocrine neoplasias (MEN) are autosomal dominant hereditary cancers which have their origin in hormone secreting glands [1]. These produce specific syndromes due to the hormones secreted. Also these hormones act as tumour markers which can be used in screening and follow up. MEN have been classically classified as MEN 1 (primary hyperparathyroidism (PHPT), pituitary adenomas, pancreatic islet cell tumours), MEN-2A (medullary thyroid carcinoma (MTC), pheochromocytoma, PHPT) and MEN-2B (MTC, pheochromocytoma, Marfanoid habitus, mucocutaneous neuromas). At times these syndromes have overlapping or additional features. We report a case of MEN-2B which has many unusual features.
