Sweet's Syndrome (Acute Febrile Neutrophilic Dermatosis)

The second male patient with classical Sweet's syndrome (acute febrile neutrophilic dermatosis) is reported and the 17 previously published cases are reviewed. All of the present patient's signs and symptoms were dramatically controlled with orally administered prednisone, but temporarily recurred when treatment was discontinued prematurely. Possibly coincidentally, he was found to have a testicular tumor (embryonal carcinoma with features of teratocarcinoma) only six weeks after the onset of his dermatosis.
