Teratomas are germ cell tumors commonly composed of multiple cell types derived from one or more of the 3 germ layers. Inconsistent nomenclature often confuses discussions of various subtypes of teratomas. The word is derived from the Greek teras, meaning monster, which Virchow coined in the first edition of his book on tumors published in 1863. Teratomas range from benign, well-differentiated (mature) cystic lesions to those that are solid and malignant (immature). Additionally, teratomas may be monodermal and highly specialized. Rarely, within some mature teratomas certain elements (most commonly squamous components) undergo malignant transformation.
