Unusual Clinicopathological Presentations of Mature Cystic Teratoma: A case series

Abstract

Mature cystic teratomas also known as dermoid cyst are one of the most common benign tumors of the ovary.
It is usually seen in young women in the reproductive age group. It comprises of mature elements derived from
all the three germ layers. In this case series we reported a series of 4 cases of mature cystic teratoma of the ovary
with uncommon clinicopathological presentations. First case was a rare entity of melanocytic nevus arising from
a mature cystic teratoma. Second case was adipocyte rich teratoma, an uncommon lipomatous lesion of the ovary.
Third case was rupture of dermoid cyst presenting as acute abdomen. Fourth case was mature cystic teratoma in
a post-menopausal woman. To conclude, though dermoid cysts after surgical removal have an uneventful clinical
course, extensive sampling of the specimen for histopathological study should be done to identify rare pathologies
which bears a clinical significance.
