In some locations, nodes that contact vessels may be difficult to identify without contrast medium infusion. However, no malignant cells were seen in the mediastinoscopy samples or the trans-bronchial biopsy samples. A lymph node is a kidney-shaped organ in the lymphatic system and functions to trap bacterial and cancer cells. Fever (may come and go over several weeks) without an infection. One of the first attempted links between sarcoidosis and malignancy was a paper by Brincker in 1974 (5).
