Successful resection of mediastinal seminoma evaluated the response to induction chemotherapy with fluorodeoxyglucose-positron emission tomography

Abstract

Mediastinal seminoma is a rare malignant tumor, and the current strategy for primary mediastinal seminomas is making a prompt diagnosis and achieving an appropriate chemotherapy. However, consensus regarding the optimal post-chemotherapy management has not been reached. We experienced a case of 26-year-old man who was diagnosed mediastinal seminoma and evaluated the response to induction chemotherapy with fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT). Complete surgical excision of the tumor was performed. Pathologic findings of the surgical specimen showed no viable cells in the tumor.
