Abstract

Teratoma is a tumor derived from totipotential cells and composed of tissues originating from all 3 germinal layers. The tumor can be malignant based on histologic differentiation, size and location and is commonly found in the sacrococcygeal region, but uncommonly occurs in the head and neck region. A mature teratoma rarely occurs in the Eustachian tube. The authors of the current study present a case of a mature teratoma originating from the Eustachian tube of a 23-year-old woman who complained of left otorrhea. In addition, a review of the literature is presented.
