Background Ovarian sex cord tumours with annular tubules (SCTAT) are a very rare type of neoplasm and account for 14% of all sex cord tumours. This tumour was first described in 1970 with histopathology characterized by the presence of both complex and simple annular tubules. The tumour may show features of either granulosa cell tumours or Sertoli cell tumours and differentiation into either type can occur. Case We report an interesting case of SCTAT in a 60-year-old woman who had a primary diagnosis of granulosa cell tumour. Seven years later she experienced a recurrence. Following excision and review of all pathology, the patient was found to have a SCTAT in both the recurrence and the primary tumour. Conclusion SCTAT is a slow-growing tumour that occasionally exhibits malignant behaviour with metastatic potential, albeit many years following initial diagnosis. SCTAT should be included in the differential diagnosis of sex cord tumours.
