Background: Sarcoidosis is a chronic inflammatory disease, commonly found in lungs and hilar lymph nodes, but multiple organs could be involved. The diagnosis is based on specific pathohistology which should be always combined with clinical, radiological and laboratory findings.
Case report: A patient initially presented with pneumonia, and treated with antibiotics, but with the general symptoms that persisted despite radiological resolution of lung infiltration was reported. The further diagnostic procedures revealed the presence of sarcoid granulomas in cervical lymph nodes. The peripheral lymph nodes are often affected in the early course of the disease, but it is difficult to distinguish if the illness is a sarcoid reaction to lung infection or a acute onset of sarcoidosis.
Conclusion: The detection of sarcoid granulomas in cervical lymph nodes should be precisely analyzed for the presence of sarcoidal changes in other tissues, primarily in the lungs tissue. Early diagnosis of lung sarcoidosis is significant, especially in the light of the fact that the latest studies point out that the prednisone therapy, started immediately after the diagnosis has been made, renders positive effects also in asympthomatic patients in II and III phase of the disease.
