Ovarian sex cord stromal tumor with annular tubules in a 7-year-old child: A case report

Non-Peutz-Jeghers syndrome-associated ovarian sex cord tumor with annular tubules treated by radiotherapy: a case report and literature review

There are no standard treatment options for metastatic and recurrent non-Peutz–Jeghers syndrome (PJS)-associated sex cord tumor with annular tubules (SCTAT). The effects of chemotherapy and/or radiotherapy are still not well-defined. Herein, we present a case of a metastatic and recurrent non-PJS-associated SCTAT showing high serum estradiol and progesterone concentrations after surgery and chemotherapy. Radiotherapy (50 Gy/25 fractions) triggered a sharp reduction in the sizes of the metastatic and recurrent masses, and estradiol and progesterone concentrations. Accordingly, we consider that radiotherapy might be effective and safe for metastatic and recurrent SCTAT. The roles of radiotherapy in non-PJS SCTAT should be further validated in large-scale prospective clinical trials.

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

•

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.

•

We report the second case of a 71-year old woman with non-syndromic bilateral SCTAT.

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.
