Sarcoidosis is a multi-systemic disease. A 21-year-old female patient was admitted to our department with lymphadenopathy, B symptoms, erythema nodosum and joint pain. Sarcoidosis showed a very atypical course, lacking any pulmonary symptoms or typical laboratory values. The diagnosis was finally confirmed histologically and thus various differential diagnoses such as microbiological and malignant diseases could be excluded. Oral steroid medication led to remission.
