BCG immunotherapy often has severe complications in cancer patients despite lack of toxicity in the immunocompetent individual. MER, a cell wall fraction of BCG, has been reported to cause immunopotentiation similar to that of BCG without equivalent toxicity. Recently, animal models have been reported to develop MER complications, especially disseminated granuloma formation, like those of BCG. For the past several years, MER has been used as adjuvant immunotherapy for treatment of malignant tumors with minimal systemic toxicity reported. A patient with malignant melanoma was treated with intralesional MER at the site of local metastases. He developed military pulmonary granulomatosis and a severe cutaneous eruption in association with MER therapy. The toxicities of BCG and MER therapy were compared and the pathogenesis of granuloma formation reviewed. This patient's complications were consistent with a hypersensitivity reaction to MER. Pulmonary granulomatosis and rush must be added to the fist of known MER toxicities. Cancer 43:500–504, 1979.
