Abstract
We report a 43-year-old woman with biopsy proven Sweet's syndrome with massive mediastinal lymphadenopathy. No other clinical signs compatible with sarcoidosis were present. Mediastinoscopy was performed to establish a diagnosis. Histological evaluation revealed non-caseating granulomas compatible with sarcoidosis. We review the association of Sweet's syndrome and (haematological) malignancies, and eight other cases of Sweet's syndrome and sarcoidosis. All but one presented with erythema nodosum, making the diagnosis of acute sarcoidosis (Löfgren's syndrome) more likely than malignancy.
