Video-assisted thoracoscopic surgery for a cystic seminoma of the mediastinum

Abstract

Mediastinal seminomas are uncommon primary mediastinal neoplasms, and most are solid in appearance. Cystic mediastinal seminoma is an unusual type of extragonadal germ cell tumor that has rarely been reported in the literature. Here we describe a 36-year-old man with a 7.5-cm cystic mediastinal seminoma. The tumor was excised successfully by video-assisted thoracoscopic surgery. No recurrence was noted during 28 months of follow-up.
