Incidence of bilateral TGCT increased with >25% of metachronous TGCT presenting ≥10 years after first TGCT; possible causes include increased survivorship and referral bias. Stage was statistically similar at first and second tumor; stage at second tumor was not associated with time interval between tumors or prior treatment modality at first tumor.
