Chronic tonsillitis is a persistent inflammation of the palatine tonsils, frequently resulting from recurrent acute infections or ineffective treatment of primary tonsillitis. Clinically, the disease manifests in two primary forms: the simple form and the toxic-allergic form. This article reviews the distinguishing characteristics of each form, including symptomatic differences, systemic involvement, and laboratory findings. Particular attention is paid to the criteria used in differential diagnosis, which are essential for determining the appropriate therapeutic approach. Early recognition of the clinical form of chronic tonsillitis is crucial to prevent complications such as rheumatic fever, glomerulonephritis, and chronic fatigue syndrome.
