Primary uterine tumors and multiple endocrine adenomatosis, type I

Multiple endocrine adenomatosis, Type I was initially diagnosed in a 35-year-old woman with primary chief cell hyperplasia of the parathyroids. Approximately 5 years later, vaginal bleeding developed and a well-differentiated endometrial adenocarcinoma was recognized. An adenomatoid tumor of the uterus was discovered in addition to a nonfunctional islet cell tumor of the pancreas. Multiple endocrine adenomatosis is reviewed in relation to possible gynecologic neoplasms.
