MEN1 and multiple endocrine neoplasia type 1: The possible association of leiomyoma with MEN1 was first hypothesized in 1997 in two publications: a case report of a woman with clinical MEN1 and a history of uterine leiomyomatosis/leiomyosarcoma who was diagnosed with a lung lymphangioleiomyoma at age 60 years (92) and, as part of a larger study of 13 MEN1 patients, a 56-year-old female with MEN1 who had an esophageal leiomyoma (60).
