The contents of ovarian teratomas can be formed by tissues from two or three germ layers, including skin and its appendages, hair, teeth, nerves, fat, bones, etc. Although theoretically, these components can come from any germ layer, teratomas that fully contain various tissues are rare in practice. This article reports a special case of a female patient with Meniere’s syndrome, hypertension, obesity, and type II diabetes. Ultrasound imaging suggested an ovarian teratoma, and after surgical treatment, the teratoma was found to contain skin, hair, bones, teeth, and thyroid tissue. Regarding the specific case you mentioned, a female patient with Meniere’s syndrome, hypertension, obesity, and type II diabetes, in which ultrasound imaging suggested an ovarian teratoma, and post-surgery revealed the presence of skin, hair, bones, teeth, and thyroid tissue, this indeed represents a rare case in clinical practice.展开更多
