Post-thyroidectomy suture granuloma: A diagnosis on fine needle aspiration cytology

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.
