An allergic disease may develop in any organ or system. The respective etiological factors include foreign proteins, infectious agents such as various microbes, viruses, moulds, parasites, chemical compounds often in the form of drugs usually designated as haptens, polysaccharides, benign and malignant neoplasms. Of the factors operating in the causal pathogenesis of such diseases the most important one is an exaggerated formation of antibodies, which appears to be uncontrolled and occurring irrespective of the demands of the organism. The essential morphological features in allergic inflammation are rather variegated, their diagnostic value differing in a wide range but being never absolute. The above features include eosinophilic leucocytes, allergic arteritis and phlebitis, fibrinoid necrotic glomerulonephritis, histiocytic granulomatous inflammation or histiocytic granuloma. Granulomatous capsulitis and trabeculitis affecting the spleen and lymph nodes are believed to be of major diagnostic significance. The immunofluorescent and immunoperoxidase methods and electron microscopy are important diagnostic tools. It has been generally acknowledged that many drugs operate as antigens. They may cause death of the respective patient, but allergic manifestations may subside after withdrawal of such drugs. On occasion they operate as a trigger mechanism with the allergy progressing even after treatment had been interrupted. Therefore they have been receiving extreme attention. Our collection of cases a case of giant-cell myocarditis following sulfamethoxypyridazine, anaphylactic shock has been reported to occur after intravenous administration of novocaine, and generalized cutaneous vasculitis developed in the same patient during the subsequent phase. A similar cutaneous finding was reported to have developed after penicillin injection, granulomatous inflammation developed owing to sulfonamide treatment. Allergic tumour-like lymphadenitis developed after administration of anti-anthracic serum; an anticonvulsive syndrome developed after hydantoinate administration. The latter consisted of generalized exanthema, hepatomegaly, splenomegaly and generalized lymphadenopathy. The lymph nodes showed tumour-like lymphadenitis mimicking lymphogranuloma or reticulosis. Allergic diseases appear as either isolated organ lesions or systemic diseases. Thus, isolated and systemic polyarteritis nodosa, isolated nasal, pulmonary or systemic Wegener's granulomatosis have been recognized. Temporal arteritis has been recognized as a localized form of systemic giant-cell arteritis. The haemolytic-uraemic syndrome appears to be a milder variety of thrombotic thrombocytopenic purpura. Allergic diseases or manifestations occasionally affect two or more organs or systems.
