Hemophilia B

Hemophilia B is a form of hemophilia (see this term) characterized by spontaneous or prolonged hemorrhages due to factor IX deficiency.

Cholesteatoma

Cholesteatoma is a benign but potentially destructive growth consisting of keratinizing epithelium located in the middle ear and/or mastoid process. In cholesteatoma, a skin cyst grows into the middle ear and mastoid. The cyst is not cancerous but can erode tissue and cause destruction of the ear.
