An immature teratoma is a teratoma that contains anaplastic immature elements, and is often synonymous with malignant teratoma. [1] A teratoma is a tumor of germ cell origin, containing tissues from more than one germ cell line, [2] [3] [4] It can be ovarian or testicular in its origin.
Large numbers of lobules coalescing into a definitely elevated mass may be called benign sebaceous hyperplasia, and occasional small keratin-filled pseudocysts may be seen and must be differentiated from epidermoid cyst or dermoid cyst with sebaceous adnexa.
Pseudocysts are like cysts, but lack epithelial or endothelial cells. Initial management consists of general supportive care. Symptoms and complications caused by pseudocysts require surgery. Computed tomography (CT) scans are used for initial imaging of cysts, and endoscopic ultrasounds are used in differentiating between cysts and pseudocysts.
