| dc.description.abstract | We report a case of a mature cystic teratoma (MCT) of the ovary in a
44-year-old woman, characterized by both solid and cystic components
derived from all three germ layers: ectoderm, endoderm, and mesoderm.
This patient presented with non-specific abdominal discomfort and
abdominal bloating for a couple of years. A pelvic ultrasound scan (USS)
showed a large complex ovarian tumour with a CA 125 level of 74U/ml.
Due to the high calculated Risk of Malignancy Index (RMI), a diagnostic
dilemma arose. Consequently, a total abdominal hysterectomy, salpingo
oophorectomy, and partial omentectomy were performed, given the
suspicion of a malignant ovarian tumour. Macroscopically left ovary was
enlarged with a nodular cystic mass. The cut surface showed a multilocular
cyst filled with mucoid fluid. Some loculi contained hair and sebaceous
material. Microscopically the solid areas of the cyst wall were largely
composed of thyroid tissue (10%), the rest of the cyst wall contained
mature skin adnexal structures including hair, salivary glands, adipose
tissue, bone, lymphoid tissue and smooth muscle. | en_US |
