Mature teratomas include dermoid cysts and are generally benign. [8] Immature teratomas may be cancerous. [4] [9] Most ovarian teratomas are mature. [10] In adults, testicular teratomas are generally cancerous. [11] Definitive diagnosis is based on a tissue biopsy. [2] Treatment of coccyx, testicular, and ovarian teratomas is generally by surgery.

Ovarian squamous cell carcinoma typically presents with a mean tumor size of 14.8 cm, and overall survival does not vary based on tumor size.
