Examination shows lymphoid hypoplasia (tonsils and adenoids, no splenomegaly or lymphadenopathy). Sarcoidosis patients suffering acute arthritis often also have bilateral hilar lymphadenopathy and erythema nodosum. Mediastinal lymphadenopathy or mediastinal adenopathy is an enlargement of the mediastinal lymph nodes. In later stages hilar lymphadenopathy, interstitial pulmonary fibrosis and pleural thickening. Effects of infection include granulomatous lymphadenopathy, pneumonitis, pharyngitis, skin infections, and endocarditis. Lymph node enlargement or swelling is known as lymphadenopathy. Pericardial fluid filling these recesses may mimick mediastinal lymphadenopathy. It appears to be effective and leads to improvement of lymphadenopathy and splenomegaly. From here they can disseminate further to mesenteric lymph nodes causing lymphadenopathy. Lymphadenopathy, edema, tachycardia and fresh blood appearing in human victim feces are common symptoms. This syndrome consists of fever, rash, peripheral leukocytosis, lymphadenopathy, and occasionally hepatic necrosis. Lymphadenopathy (swollen glands) is common in sarcoidosis and occurs in 15% of cases. This cervical lymphadenopathy may be reactive or metastatic. Joint pains, red cell aplasia, pancreatitis and generalized lymphadenopathy are the possible extrahepatic manifestations. In children, most palpable cervical lymphadenopathy is reactive or infective.
