[citation needed] The common feature among the three sub-types of MEN2 is a high propensity to develop medullary thyroid carcinoma. A variant of MEAs 2A was described in 1989. [7]
Medullary thyroid carcinoma may also produce a thyroid nodule and enlarged cervical lymph nodes. [4] Sites of spread of medullary thyroid carcinoma include local lymph nodes in the neck, lymph nodes in the central portion of the chest (mediastinum), liver, lung, and bone. Spread to other sites such as skin or brain occurs but is uncommon.
