Background. A mild reaction to surgical sutures after thyroid surgery is common and is characterized by local edema and inflammation around the surgical scar. Severe reaction with microabscesses and granulomatous masses is quite rare. Methods and Results. Two cases of severe reaction to silk sutures after thyroid surgery are presented, Meticulous surgical removal of all surgical sutures along with granulomatous masses, granulation tissue, and microabscesses cured both patients. Pathologic examination revealed giant cells and lymphocytes. Intradermal skin tests were positive to silk sutures. The etiology and the treatment options are discussed. Conclusions. In rare cases, severe reaction to silk sutures may develop after thyroid surgery. Surgical removal of the stitches is the treatment of choice. Intradermal skin test is a good predictor of allergy to sutures.
