Suture granulomas result from the use of nonabsorbable suture and is an infrequent complication following thyroidectomy. When they occur, suture granulomas may mimic both benign and malignant diagnoses, posing a potential diagnostic challenge. Ultrasound-guided fine needle aspiration cytology is an accurate diagnostic modality for the workup of nodules within the thyroidectomy bed. We herein present 2 cases of post-thyroidectomy suture granulomas, presenting as a painless, palpable mass in the surgical bed and occurring as a late complication of thyroidectomy that were diagnosed on fine needle aspiration cytology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
