APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Teratoma is a tumor of embryonic origin, composed of various tissues derived from three germ layers (ectoderm, endoderm and mesoderm), which differentiate to form somatic tissues (1). The teratoma may comprise either well-differentiated (mature) or primitive (immature) tissue.

Detailed explanation-2: -A variety of mature, well-differentiated tissue elements may be found from all three embryologic germ layers (ectoderm, mesoderm, endoderm). These tumors are often called “dermoid cysts” because they are mostly cystic and mostly contain ectodermal elements, typically resulting in the abundant hair seen here.

Detailed explanation-3: -Teratomas are congenital tumors from ectodermal, endodermal, and mesodermal origin, ranging from benign, composed of well-differentiated cells arranged in a pattern resembling a normal tissue (mature), to malignant incompletely differentiated tissues resembling fetal tissues (immature).

Detailed explanation-4: -Mature teratomas are the most common type of ovarian germ cell tumour. They are non cancerous (benign). Mature teratoma is also often called a dermoid cyst. They are most common in women during their reproductive years (from teens to forties).
