Norfloxacin-Induced Linear IgA Dermatosis.

Abstract

A 60-year-old cachexic man visited the dermatology outpatient department with fluid-filled lesions on much of his body. He had an intermittent high-grade fever, diarrhea, and vomiting for the past 2 months associated with weight loss and decreased appetite. He admitted to having taken norfloxacin 400 mg twice daily for 3 days for diarrhea, 5 days prior to the onset of the lesions. Physical examination revealed pallor and significant lymphadenopathy (cervical, axillary, and inguinal), and his body mass index (BMI) was 17.67. There were generalized, bizarre-shaped, discrete, as well as coalescing, vesicles and bullae over a diffusely erythematous skin. Characteristic "string of pearls morphology" could be seen over the trunk (Figure 1A and 1B). The trunk exhibited sheets of skin peeling with underlying erosions and Nikolsky sign was positive (Figure 1C), although there was no cutaneous tenderness or mucosal involvement. A Tzanck smear revealed the presence of neutrophils and eosinophils but no acantholytic cells. There was moderate hepatomegaly (7 cm below the costal margins).
