Primary germ cell tumor of the mediastinum - presenting as a huge mass

Abstract

Germ cell tumors compromise 15-20% of all anterior mediastinal masses; 50-60% of these 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.
