Neutrophilic dermatosis of the hands (localized Sweet's syndrome) in association with chronic hepatitis C and sarcoidosis.

Hepatitis C may be the triggering factor for both Sweet's syndrome and sarcoidosis through stimulation of T helper 1 immune responses involved in the pathogenesis of both diseases.
