Sweetʹs syndrome after pneumonectomy

We report the case of a 38-year-old woman in whom typical skin lesions of Sweetʹs syndrome developed 2 days after undergoing left pneumonectomy, which was done because of severe bronchiectasis related to remote chemotherapy and radiotherapy given for lung sarcoma at the age of 8 years. Later fever and leukocytosis appeared, and biopsy results of the skin lesions showed neutrophilic infiltration of the dermis compatible with the diagnosis of Sweetʹs syndrome. Postoperative Sweetʹs syndrome has been reported only twice in the world literature. These other two cases and possible pathogenic mechanisms are reviewed.
