[A case of resected lung cancer associated with bullous pemphigoid]

Abstract

The relationship between bullous pemphigoid and malignancies of visceral organs is still controversial. A case of lung cancer associated with bullous pemphigoid is reported. A 63-year-old man admitted hospital because of multiple bullae of the whole body skin and continuous fever. The skin lesions were diagnosed as bullous pemphigoid by the skin biopsy. However, the chest x-ray on admission revealed a large tumor in the left upper lung field. The tumor was diagnosed as a lung cancer by trans-bronchial lung biopsy. The fever withdrew with the administration of prednisolone. The left upper lobectomy of the lung and mediastinal lymph node dissection were performed. The skin lesion disappeared 5 days after the surgery. This clinical course is thought to indicate the relationship of both diseases. Bullous pemphigoid is thought to have many problems during perioperative period, such as hypoproteinemia and delayed wound healing due to administration of the steroid, therefore intensive care is necessary in the perioperative care.
