Non-syndromic bilateral ovarian sex cord stromal tumor with annular tubules in a postmenopausal elderly woman as an incidental finding.

INTRODUCTION

Sex cord tumors with annular tubules (SCTAT) are very rare neoplasms comprising less than 1% of sex cord ovarian tumors. They usually occur in women of reproductive age and tend to be associated with Peutz Jeghers Syndrome (PJS), be bilateral, multifocal, and small. When diagnosed in older patients they are often described as sporadic, unilateral, predominantly cystic and bigger.

CASE PRESENTATION: A bilateral hysterosalpingo-oophorectomy was performed in a seventy-one year-old-woman with postmenopausal bleeding showing no features of PJS. A bilateral SCTAT was diagnosed, associated with a focus of Leydig cell hyperplasia, an endometrial polyp and endomethroid intraepithelial neoplasia.

DISCUSSION: SCTAT is a very rare histological variant in postmenopausal women. The case we present is special, different to what has been reported in the literature regarding these tumors.

CONCLUSION

It is important to be aware that SCTATs can also be present in older women, they can be bilateral despite not being related to PJS syndrome and must be considered as a differential diagnosis in ovarian tumors.
