A 50-year-old female with pendulous tonsil in the upper portion of right palatine tonsil is reported. She had developed pustulosis palmaris et plantaris, which has been one of the most common focal infections in chronic tonsillitis, during the past 10 years. Tonsil provocation test was performed and an apparent worsening of pustulas was seen. Excision of pendulous tonsil from the palatine tonsil was performed under local anesthesia. The excised pendulous tonsil was 25 × 20 × 17 mm, and histological findings revealed an accumulation of keratin extract in addition to tonsillar tissue. After the excision, pustula did not recur during one-year follow-up, suggesting that the pendulous tonsil might have been a focus for pustulosis palmaris et plantaris in this case.
