[Swollen parotid gland and lower leg erythema. Presentation of differential diagnosis and therapy based on a case report].

A 20-year-old woman developed erythema of the lower legs and swelling of both parotid glands. Her lung function parameters were initially unremarkable, and only discrete pulmonary-hilar changes were visible on the chest X-ray, and acute sarcoidosis was considered as one of the possible differential diagnoses. The paper describes in detail the diagnostic approach and the establishment of the differential diagnosis. The first attempts at therapy with the non-steroidal antiinflammatory drug diclofenac were unsuccessful, but treatment with glucocorticoids that was thereupon tried proved effective.
