Bazex syndrome mimicking a primary autoimmune bullous disorder.

Bazex syndrome is a paraneoplastic condition that is most frequently associated with squamous cell carcinoma of the upper aerodigestive tract. The lesions affect acral areas of the skin, including hands, feet, ears, nose, and, to a lesser extent, elbows and knees. Lesions mimic psoriasis and dermatitis. Paronychia and nail dystrophy are frequent. Bullous lesions have been reported only rarely. We report a patient with Bazex syndrome with predominantly bullous lesions that mimicked a primary autoimmune bullous disorder.
