Multiple endocrine neoplasia (MEN) type 2A is a multiglandular tumor condition inherited in an autosomal dominant manner. It is related to proto-oncogene RET mutation whose analysis is the best technique for family screening. It features in a variable way medullary thyroid cancer (MTC), primary hyperparathyroidism (HPT) and pheochromocytoma.

Methods: After a family tree establishment of a MEN 2A index case, a family survey allowed to diagnose other cases in the family by means of biological, radiological and/or genetic examinations. Results: We report a family form of MEN 2A in a family of three households. In this family 13 people (index case included) were probed out of 34 members. The average age of our patients was 43.54. The sex ratio men/women was 0.85. The simultaneous diagnosis of a primary HPT and a MTC was carried out in our index case and constituted the circumstance of discovery of MEN 2A. The time limit of MEN 2A diagnosis on the other family members was on average 7.7 years. A MTC was recorded in 7 patients. It was asymptomatic in overall cases. A pheochromocytoma was present in only one patient. Primary HPT was found in four patients. Renal lithiasis with recurrent unilateral or bilateral nephritic colic attacks was the main manifestation. Besides the index case, 11 patients had a genetic testing. In 7 patients, a mutation on proto-oncogene RET located on
