Bmc Ear, Nose and Throat Disorders Open Access Hamartomas, Teratomas and Teratocarcinosarcomas of the Head and Neck: Report of 3 New Cases with Clinico-pathologic Correlation, Cytogenetic Analysis, and Review of the Literature
Background: Germ-cell tumors (GCT) are a histologically and biologically diverse group of neoplasms which primarily occur in the gonads but also develop at different extragonadal sites in the midline of the body. The head and neck region including the upper respiratory tract is a very rare location for such tumors in both children and adults, which can cause diagnostic and therapeutic difficulties.
