To the editor: The facultative anaerobe Eikenella corrodens is a recognized human pathogen (1–5), but its pathogenicity still requires further documentation. We recently saw two patients who were infected with this microorganism.
A 64-year-old man had poorly differentiated neoplasm in peritoneum, mesentery, diaphragm, and lungs. He also had ascites with malignant cells. The primary site was unknown. Unclassifiable sarcoma was suspected, and treatment was begun with vincristine, cyclophosphamide, doxorubicin, and 5-fluorouracil. The patient was anergic, became febrile, and developed pulmonary infiltrates. His sputum grew Klebsiella pneumoniae, Candida albicans, and Candida tropicalis. He became hypoxic (PO2 48 mm Hg) with CO2
