Blistering on a squamous cell carcinoma graft site in a patient with bullous pemphigoid.

Bullous pemphigoid is a blistering disorder with blisters arising from normal, otherwise uninvolved tissue or from urticarial or erythematous plaques localized mainly on the trunk or upper extremities. Neoplasms, such as squamous cell carcinomas, have also been reported in patients with bullous pemphigoid. Large squamous cell carcinomas (greater than 8 cm in diameter) are best treated by surgical excision. We report a patient with bullous pemphigoid and squamous cell carcinoma who showed blisters on his graft site.
