They behave unpredictably and often have a late recurrence making counseling management and prediction of prognosis challenging. Case presentation A 52-year-old Moroccan woman with an sex cord-stromal tumors underwent a bilateral oophorectomy. The histology was unusual but was likely to be a luteinized thecoma with suspicious features for invasion. Seven years later after a gastrointestinal bleed a metastasis within the small bowel mucosa was detected. This represents probable isolated hematogenous or lymphatic spread which is highly unusual especially in the absence of concurrent peritoneal disease. Conclusions To the best of our knowledge this is the second reported case of an sex cord-stromal tumors recurring in small bowel mucosa and mimicking a primary colorectal tumor. This highlights the diverse nature and behavior of these tumors. Introduction Sex cord-stromal tumors SCSTs of the ovary are uncommon neoplasms that account for 5 to 8 of all ovarian malignancies 1 . Their histopathologic appearance and malignant potential are highly variable making the optimum treatment of these tumors difficult to establish. The group includes granulosa-stromal tumors fibroma-thecoma Sertoli-stromal cell tumors steroid cell tumors and SCSTs of mixed or unclassifiable type. The unpredictable behavior and often late recurrence of these tumors make counseling of patients about subsequent management and prognosis a major challenge. We present an unusual case of an SCST that in keeping with the variable behavior of these tumors was difficult to classify. Case presentation We report the case of a .
