1. Dermoid cysts are usually unilocular swelling with smooth surfaces, seldom attaining more than 15 cm in diameter.
2. They contain sebaceous material and hair and the wall is lined in part by squamous epithelium which contains hair follicles and sebaceous glands.
3. Teeth, bone, cartilage, thyroid tissue and bronchial mucous membrane are often found in the wall.
4. Dermoid cysts frequently arise in association with pseudomucinous cystadenomas to form a combined tumor.
5. They are not infrequently bilateral, 12%. Dermoid cysts are innocent ovarian tumors but epidermoid carcinoma occurs in 1.7% of all dermoids and sarcomatous can occur.
