Clinical data were collected, including demographic characteristics and acute phase reactants (erythrocyte sedimentation rate, high\u2010sensitivity C\u2010reactive protein). The visual analog scale (VAS), Palmoplantar Pustule Psoriasis Area Severity Index (PPPASI) and Nail Psoriasis Severity Index (NAPSI) were used to measure the severity of bone pain, skin lesions and nail lesions, respectively. Patients were referred to the otolaryngology department for tonsil examinations, including tonsil hypertrophy (grade\u00a0\u2265\u00a02), chronic congestion, inflammatory secretion and tonsil stones. The patients who underwent tonsillectomy were followed up after the surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 67.2% of patients had tonsillitis.
