Warts similar in structure to those of the skin occur onmucous membranes with a covering of squamous epithelium,such as the lips, buccal aspect of the cheeks, vestibule ofthe nose, and the larynx. The oesophagus of the ox is occa-sionally the seat of a multitude of dendritic warts. Laryngeal warts.—In the larynx, warts most commonlyspring from the mucous membrane covering the true cords ;.

The child died frequently they grow immediately beneath the cords, and anot uncommon situation is immediately below the point ofattachment of the vocal cords to the thyroid cartilage. Ex-ceptionally a large mulberry-like wart has been detectedgrowing from the floor of the sinus pyriformis. In numberlaryngeal warts vary greatly. Often but one is present; in othercases ten or more will be found. In size there is great differ-ence : some Avarts are not larger than the head of a pin; theyrarely exceed the dimensions of a small cherry, and as a rulethey are no bigger than split peas. The warts may be sessileor pedunculated; in the latter case they sometimes possessgreat mobility, and get nipped between the vocal cords and 238 EPITHELIAL TUMOURS o-ive rise to urgent dyspnoea, which occasionally ends insuffocation (Fig
