Pseudoprecocity in an Infant due to a Luteoma of the Ovary

Abstract
A case of pseudoprecocity in an 10-month-old girl is reported. Hormone assays in the urine showed only a mild rise in pregnanediol excretion; the vaginal smear showed a pattern similar to that seen in an adult in the luteal phase of the menstrual cycle. Removal of a solid right ovarian tumor resulted in cure, and histolog-ical examination showed it to be a luteoma of the ovary.
