Primarygerm Cell Tumor of the Mediastinum

Abstract

Germ cell tumors compromise 15-20% of all anterior mediastinal
masses; 50-60% ofthese are benign mediastinal teratoma. There
may be mature, immature, and rarely with malignant component
within the tumor mass. There are more chances of malignancy
with immature type. We are reporting a case in 20-year young male
diagnosed as giant benign cystic teratoma which was adherent
to superior vena cava. The patient underwent surgical excision.
In follow up of 2 years, the patient is not having any complaints.
