title: [Mature cystic teratoma of the ovary with a small ganglioneuroma].
abstract: A case of ganglioneuroma arising within a cystic mature teratoma of the ovary in a 34-year-old woman is reported. Patient underwent right adnexectomy. The ovary was completely replaced by a bilocular cystic lesion, measuring 8 cm in diameter and filled with adipose tissue and pilosebaceous material. Microscopically the cyst was composed by a mature cystic teratoma containing skin with dermal appendages, fatty tissue and bronchial epithelium. Furthermore a nodule (0.5 cm in size) composed of mature ganglion cells, axons and Schwann cells, was identified. Ganglion cells were positive for NSE and synaptophysin, while Schwann cells stained positively with S100 protein and GFAP. To the best of our knowledgment this is the first reported cases of ganglioneuroma arisen within a cystic mature teratoma of the ovary.
