Abstract

Germ cell tumors, in particular teratomas, are some of the most commonly found tumors in childhood. Six percent of all germ cell tumors are located in the head and neck region. Endodermal sinus tumors (yolk sac tumors) of the head and neck, exclusive of the central nervous system, are rare. This study reports a 20-month-old girl with a mass of 5 x 5 cm on the left temporal area and with bone destruction on CT. The histopathological examination of the excised mass revealed an endodermal sinus tumor. The serum AFP and the LDH levels were elevated at diagnosis. The patient was treated by the BEP protocol (bleomycin, etoposide, and cisplatin), six cycles every three weeks. Partial response was attained after the first and complete response after the fourth cycle. The patient, who is being followed up, has been in remission for five months.
