Estrogen secretion from a malignant sex cord stromal tumor in a patient with complete androgen insensitivity, ,

We report on a 68-year-old patient with complete androgen insensitivity syndrome (testicular feminization syndrome) in whom an estrogen-secreting malignant sex cord stromal tumor developed in an intraabdominal testis. We believe this to be the first such case to document estrogen secretion by the tumor.(Am J Obstet Gynecol 1997;177:1541-2.)
