Bilateral ovarian mature cystic teratoma co-existing with granulosa cell tumour: a case report
Abstract
Background: Mature granulosa cell tumour (GCT) is a rare neoplasm. it accounts for about 1-2% of all ovarian tumours. Even more infrequent is the coexistence of GCT with mature cystic teratoma in the same ovary. Case presentation: A 53-year-old woman with constipation, abdominal swelling, and pain presented to our gynaecology clinic. Physical examination revealed a distended abdomen, ascites, cystocele, stress incontinence, and external haemorrhoids. A cystic teratoma co-existing with a granulosa cell tumour was diagnosed histologically. Adjuvant chemotherapy containing Cisplatin [75mg/m2] and Docetaxel [75mg/m2]) was completed, followed by radiotherapy. She has been clinically stable for two years and is currently on long-term follow-up to forestall recurrence. Conclusion: The coexistence of mature granulosa cell tumour (GCT) with mature cystic teratoma especially in the same ovary is an extremely rare pathology. Although total abdominal hysterectomy and bilateral salpingo-oophorectomy are the treatments of choice in postmenopausal and perimenopausal women, these may not always be feasible owing to the nature of the presentation. Adjuvant chemotherapy and radiotherapy may be beneficial as high cases of recurrence have been reported. Follow-ups are strongly advocated due to the recurrence that can occur even as late as 20 years following the removal of the primary neoplasm.
