Krukenberg Tumor of Ovary During Pregnancy: Learning From A Mistake.

Sertoli-Leydig cell tumor of the ovary with heterologous differentiation is a relatively uncommon tumor that occurs in females of variable age range. Krukenberg tumor (KT) is a relatively more common tumor of the ovary although only a few cases of KT occur during pregnancy making it an equally uncommon tumor in this setting. We received a unilateral ovarian mass in a 25-yr-old primigravida which we reported as Sertoli-Leydig cell tumor with heterologous (intestinal) differentiation based on its clinical and histomorphologic features. However, on further investigation, a gastric mass was found which was a signet-ring cell adenocarcinoma. We rectified our diagnosis of ovarian mass as KT. We retrospectively analyzed the reasons for our mistake and concluded that the rarity coupled with the nonclassic clinical features and histomorphology of KT during pregnancy pose challenges to the correct diagnosis. This report highlights the diagnostic challenges faced by us along with the ways to circumvent them in the future.
