Unusual Case of Mature Cystic Teratoma Showing Rare Tissues: A Case Report

Abstract

Background: Teratomas are known to show a wide variety of tissues in their microscopic analysis; however, the most common types are lined by skin-like structures and are known as dermoid cysts. The immature and monodermal types show immature neuroectodermal tissue and specialized tissue like thyroid respectively.Case description: We describe an unusual case of a 32-year-old female with an ovarian cystic mass, which was diagnosed as mature cystic teratoma, which showed a significant proportion of thyroid tissue and retinal pigmented epithelium. Conclusion: These tissues are mostly associated with specialized (monodermal) and immature teratomas. The fact that they were seen in this case of mature cystic teratoma prompted this case report.
