Recurrent prurigo nodularis related to infected tonsils: a case report

Abstract

Abstract Introduction Prurigo nodularis is an unusual disorder of unknown aetiology, which is notoriously resistant to therapy, and is characterized by extremely pruritic nodules with well-defined clinical symptoms and histopathological findings. Case presentation We report the case of a patient presenting with pruritic papules and nodules on his legs, arms and trunk over the past 4 years, recurring after episodes of acute tonsillitis. Although oral and topical corticosteroids, oral antibiotics and emollients were used in his therapy, only tonsillectomy finally proved the definitive treatment. Conclusion We discuss the aetiopathogenesis, diagnosis and treatment of prurigo nodularis associated with chronic tonsillitis, and we further review the literature on this rare condition.
