A Case of Eustachian Tube Mature Teratoma in Neonate / 대한이비인후과학회지

ABSTRACT

Teratoma is a tumor derived from the three basic germ cell layers (ectoderm, mesoderm, endoderm) and is commonly found in the sacrococcygeal region. But teratomas of the head and neck are uncommon tumors which comprise between five and 15% of all teratomas. Of these, the Eustachian tube is an unusual site for this tumor. Patients with these tumors have symptoms related to difficulties with swallowing and respiration that could result in high degree of morbidity and mortality by virtue of size and location of the tumor. We present a case of eustachian teratoma in a female infant presenting dyspnea at birth with a review of the literature.
