CASES FOR DIAGNOSIS Intermittent Vesiculous Eruption in a Child
نویسنده
چکیده
Blood tests were requested, including a complete blood count, biochemistry, antinuclear antibody, and extractable nuclear antibody, and measurement of porphyrins in blood, feces, and 24-hour urine; all the results were normal. Histopathology Biopsy of a vesicle was performed, revealing an intraepidermal blister with a few necrotic keratinocytes and an abundant dermal inflammatory infiltrate (Figure 3). Direct immunofluorescence was negative. The patient was a 10-year-old boy with no relevant personal or familial medical history, who attended our clinic for recurrent episodes of lesions on areas exposed to light. These lesions had started 3 years earlier and occurred mainly in the summer months. On physical examination, the patient presented polymorphic lesions on the face, ears, and forearms. Vesicles measuring about 2 mm diameter and filled with serous fluid were observed (Figure 1), together with scabs and a large number of depressed scars of vacciniform appearance (Figure 2).
