title: Clinical and ultrastructural findings of an androgenizing Krukenberg tumor in pregnancy.
abstract: A clinical and ultrastructural study of an androgenizing Krukenberg tumor in pregnancy is presented. Ultrastructural observations suggested the abundant, hyperplastic, luteinized ovarian interstitial cells as the probable cause of elevated circulating levels of testosterone (5400 ng/dL). The unusual fine structure of these cells, which included large intramitochondrial lipid droplets and abundant smooth endoplasmic reticulum, was indistinguishable from that reported to occur in Leydig cells stimulated by exogenous gonadotropins.
