Granulosa cell tumours of the ovary are rare, comprising around 3% of ovarian tumours. These tumours have preponderance for local spread and extremely late recurrence. Although previous cases of recurrence have been described, it is extremely unusual for these tumours to recur after thirty years. We describe a case of recurrence of granulosa cell tumour after 30 years, presenting as small bowel obstruction. The patient had not been followed up after the original surgery, and on histological analysis, recurrence of the original tumour was confirmed. This case report emphasises the necessity for lifelong follow-up of patients who have had these tumours excised, and also the unusual way in which these tumours can recur.
