Vocal fold polyps and nodules are caused by inflammation caused by stress or irritation. Our study involved looking retrospectively at 30 patients. A clinical diagnosis was established by an otolaryngologist and voice pathologist through videostroboscopic analysis. Histological sections after removal of the vocal fold lesion were available for microscopic examination. All of these cases have also been previously evaluated and photographed. A clinical diagnosis of either a polyp or a laryngeal nodule have been made and documented. Two pathologists made the histological evaluation separately initially unaware of the clinical diagnosis. Their impression was recorded. After the clinical diagnosis become available and comparison between the clinical and pathological diagnosis were made, a retrospective review of the tissue was attempted to reconcile the differences. In conclusion, after careful histological evaluation, no definitive histological distinction can be made between laryngeal nodules and polyps. Our data showed no distinction between the two entities when compared for the presence of edema, fibrin, inflammation, and amyloid-like material. A statistically significant difference was found in the size of the specimen and the presence of telangiectasias. Based on our data, a biopsy larger than 0.3 cm could be a polyp and a biopsy less than 0.3 cm could be a nodule.
