Febrer AM, Auguet MT and Roig S
Context: Acute febrile Neutrophilic Dermatosis, also known as Sweet’s Syndrome, was first described in 1964 by Dr. Robert Sweet. There have been described four many subtypes: classic type (majority of cases), cases associated with neoplasia, cases associated with inflammatory disease and cases associated with pregnancy. There have been also seen cases associated with drugs.
Case Report: We report the case of a 43-year-old woman who presented fever and skin lesions which affected mostly the neck, neckline and upper-back. The biopsy was compatible with Sweet’s Syndrome (SS). Laboratory testing revealed a positive serology for acute Parvovirus B19 infection.
Conclusion: After excluding main cases of SS, we hypothesize that in our patient it was related to acute Parvovirus B19 infection.
