Final answer:
Laryngeal polyps are benign tumors of the larynx, which can affect the voice but are not a type of infection or malignant tumors. They are unrelated to the lymphoid tissues.
Step-by-step explanation:
Laryngeal polyps are benign tumors of the larynx. They are not a localized infection of the larynx or malignant tumors of the trachea. These polyps can cause voice changes and hoarseness, and they may be caused by vocal strain or other irritants. Laryngeal polyps are generally not associated with the lymphoid tissues such as tonsils, Peyer's patches, bronchus-associated lymphoid tissue, or mucosa-associated lymphoid tissue.
