Outline
Text
During ambulance service we saw a 66 year old patient with increasing hoarseness and mucus production. The clinical examnation by use of indirect laryngoscopy showed a nodular enlargement and mucous membrane redness of the right Plica vestibularis. The mucous membrane surface and vocal fold mobility was correct.
The tumorous lesion of the right Plica vestibularis was excised by CO2-laser during microlaryngoscopy. Macroscopical findings showed yellowish and lipoid-like pathological tissue.
The histological findings adduced a choristoma with a salivary gland tissue at the vestibular fold. The physical recovery was normal.
Cause of a hoarseness with tumorous growth in the larynx, malign and benign tumors deriving from epithelial cells, mesenchymal cells, hematopoietic cells as well as fulminant and specific inflammations occur more frequently than choristomas. Therefore clinical findings with an unclear degree of malignicy should be examined by microlaryngoscopic operation and histological exploration.
A choristoma of the larynx is a rarity but an important differential diagnosis for unclear hoarseness.
