Raised Serum α-Fetoprotein in Sertoli-Leydig Cell Tumor (Androblastoma) of Ovary

Abstract
Two cases of Sertoli-Leydig cell tumor (SLCT) of the ovary associated with elevated serum .alpha.-fetoprotein (AFP) levels are described. A 16-year-old girl (case 1)had a Sertoli-Leydig cell tumor containing heterologous elements in the form of mucinous epithelium: AFP was demonstrated within the Sertoli cells by immunohistochemical techniques. An 11-month-old girl (case 2) had a SLCT with a retiform pattern and heterologous elements in the form of cells resembling hepatocytes; AFP was localized in the hepatocytes by immunohistochemical techniques.
