The primary differential diagnoses include amyloid, myxoma, spindle cell (sarcomatoid) squamous cell carcinoma, and contact ulcer
Chapter Three, "Organic Disorders," contains information about laryngitis, vocal nodules, fold polyps and cysts, oedema, reinke's oedema, contact ulcer
, granuloma, dysphonia plicae ventricularis, hyperkeratosis, vocal fold paralysis, post-radiotherapy, laryngeal papilloma, scarring of the vocal folds, spasmodic adductor dysphonia, laryngeal web, sub-mucous hemorrhages, sulcus vocalis and bowing of the vocal folds.
Contact ulcer is associated with vocal abuse, intubation, and acid regurgitation.
Contact ulcer usually appears as an ulcerated, polypoid, or nodular mass (figure, A), and it most often involves the posterior vocal fold.
With which of these statements regarding a larynx contact ulcer
would Thompson (Pathology Clinic) disagree?
Esophageal dysfunction in patients with contact ulcer of the larynx.
In 1968, laryngopharyngeal reflux (LPR)--that is, GERD that affects the larynx and pharynx--was described in relationship to contact ulcers and granulomas of the larynx.
The differential diagnoses of these masses in the larynx comprise benign lesions such as laryngeal cyst, laryngeal nodules, contact ulcers
, squamous papilloma, amyloidosis or granulomatous lesions such as Wegener's granulomatosus, sarcoidosis and tuberculosis (2).
This article explores the four most common voice disorders associated with misuse of the voice: vocal nodes, contact ulcers, vocal polyps, and laryngitis.
Contact ulcers are a pair of cartilaginous structures located at the back of the larynx (Emami, 1999).
The most common disorders resulting from vocal abuse and misuse are laryngitis, vocal nodules, vocal polyps, and contact ulcers
18-24) LPR has also been reported to be associated with contact ulcers
