Abstract
Signet-ring stromal tumor is a rare ovarian neoplasm, only a few cases being reported in the English literature. We report a case of SRST of the right ovary in a 67-year-old woman who presented with abdominal discomfort and underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. The right ovary showed a part solid part cystic mass 12.5 cm in maximum diameter. On histopathologic examination, the tumor was composed of small round and oval cells with cytoplasmic vacuolization and a typical signet-ring appearance, focally admixed with fibromatous tissue. Special staining revealed that the vacuoles of the tumor cells contained no lipid, mucoprotein, or glycogen. The patient remains free of disease six months after surgery. Signet-ring tumor of the ovary is a rare variant of benign ovarian sex-cord stromal neoplasm and should be distinguished from Krukenberg tumor, the most important differential diagnosis.
