teratoma
Let an agent explain teratomas and their kinds in general terms from clinical sources, describe sites, diagnosis and treatment approaches, distinguish mature from immature and malignant forms, and route personal questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain teratomas and their kinds in general terms from clinical sources, describe sites, diagnosis and treatment approaches, distinguish mature from immature and malignant forms, and route personal questions to clinicians.
A tumour made up of tissues from several germ layers, such as hair, teeth, bone and glandular tissue, arising from germ cells most often in the ovaries and testes and also in the mediastinum, sacrococcygeal region and elsewhere, ranging from mature cystic teratomas that are usually benign to immature and malignant teratomas, and occurring in children and adults; teratomas are diagnosed by imaging and pathology and treated by surgery and, for malignant forms, chemotherapy.
What it is for: Not applicable; a tumour type.
It can be explain kinds and sites; relay diagnosis and treatment; distinguish benign from malignant forms; route personal questions.
Distinguishing features
Multiple germ layers
Germ cell origin
Benign to malignant spectrum
Distinctive contents
What it looks like
A cystic or solid mass, sometimes containing hair, teeth or bone.
Physical character
mature cystic teratoma share of ovarian tumours: about 20 percent
sacrococcygeal teratoma incidence: about 1 in 35000 births
How it is recognised
Germ cell tumour with multiple tissue types
Mature cystic, immature and malignant teratomas of ovary, testis, mediastinum and other sites
Other germ cell tumours such as seminoma lack multi-tissue differentiation; hamartomas are malformations

- How should guidelines be linked?
- The registry entry has merged aliases naming sites and age groups; should they be split off?
