Combination of granulosa cell tumour and carcinoid in an imitation of appendix vermicularis within a mature teratoma--a unique case.

A case of primary carcinoid of the ovary in association with an imitation of appendix vermicularis is presented. These elements were thus parts of a mature teratoma. In the other ovary a granulosa cell tumour with a similar morphology was found. Following surgery no additional treatment was administered and the patient is well 13 years after the diagnosis.
