Complete Small Bowel with a Dysplastic Foci in Mature Cystic Teratoma of the Ovary: Case Report

Fernandez Vinola

Introduction: Mature cystic teratomas otherwise called dermoid cysts, are the most common ovarian tumors and account for a vast majority of germ cell tumours with highest incidence in women of reproductive age group. They contain elements originating from all three embryonic germ cell layers.

Case report: A 14 years old female presented with complaints of abdominal pain and vomiting since 1 week. On further investigations, USG showed features suggestive of dermoid cyst-right ovary. Right sided oophorectomy was performed and the specimen was sent for histopathological examination. Grossly, the specimen showed multiloculated cyst filled with pultaceous material and tuft of hair. Microscopy showed fibro-collagenous cyst wall lined by stratified squamous epithelium containing adnexal structures and complete small intestine composed of all four layers of mucosa, submucosa, muscularis propria and serosa. Foci of well-formed mucosa showing mild dysplastic changes was also noted.

Conclusion: Mature cystic teratoma of the ovary frequently contains intestinal-type tissues, but these rarely organise into complete intestinal wall with all layers. We hereby report a case of mature cystic teratoma with a rare presentation of complete small intestinal structure showing mild dysplastic changes.
