Mixed germ cell tumour of the testis 1. Embryonal cell carcinoma. 2. Teratoma. 3. Seminoma. A testicular teratoma, unlike ovarian teratoma, is often aggressive in its biological behaviour, and often exists as part of testicular mixed germ cell tumours. Mature teratomas tend to be cystic with heterogeneous echoes in the fluid representing a mixture of mucinous or sebaceous material with or without hair follicles.

Archaeologists have found the 1,600-year-old skeleton of a Roman woman who had an ovarian teratoma, the first to be recorded in the ancient world. Such benign tumors originate from germ cells, which normally become human eggs and so can form other body parts. This particular tumor had calcified in her pelvis and contained bone and four deformed teeth.
Teratoma with fully formed tooth and hair. A teratoma is an encapsulated tumor with tissue or organ components, which whilst normal in themselves, may be quite different from surrounding tissues. Teratomas have been reported to contain hair, teeth, bone and, very rarely, more complex organs and body parts such as eyes, hands, feet, or other appendages. This particular teratoma consists of a tooth and hair which have formed inside an ovary. UCL Pathology Collections: Photograph Gemma Angel.
Calcified teratoma found in pelvis of Roman woman. Archaeologists working in the necropolis in Spain have found the 1,600-year-old remains of a Roman woman with a calcified tumor in her pelvis. The tumors come from germ cells, which form human eggs and can create hair, teeth and bone, among other structures. There are some really good pictures of the actual tumor on this website.
