Linear IgA bullous dermatosis

QUESTION 76

A 74-year-old woman with a history of chronic obstructive pulmonary disease presents to the hospital with fever, cough and shortness of breath. A chest X-ray demonstrates multifocal pneumonia and she is started on broad-spectrum antibiotics including vancomycin and piperacillin–tazobactam. During her hospitalization, she develops a bullous eruption on the trunk and dermatology is consulted. On examination, there are many tense vesicles and bullae on an erythematous base filled with serous fluid, some arranged in an arcuate pattern (76a).
