We report a case of a 33-year-old male with a mixed germ-cell testicular tumor. Postoperative follow-up FDG-PET revealed concentration of FDG in the left inguinal area which is not tumor metastasis or local recurrence but suture reactivity granuloma. In this paper. we reviewed suture granulomas associated with false-positive findings on FDG-PET after surgery. https://cosmeticssquadets.shop/product-category/baby-oils/
