Physicians have been reminded repeatedly of the many faces of bacterial endocarditis. In this case, Corynebacterium endocarditis presented as an occult malignancy and eluded diagnosis for six months. The coryneform isolates found in cultures are often considered to be contaminants because of their ubiquitous nature, sometimes causing a delay in diagnosis. Patients with culture-negative endocarditis or Corynebacterium "contamination" should be treated as having Corynebacterium endocarditis pending results of microbiologic isolation tests.
医生们已被反复提醒细菌性心内膜炎有多种表现形式。在这个病例中，棒状杆菌心内膜炎表现为隐匿性恶性肿瘤，且在六个月内未被诊断出来。培养物中发现的棒状杆菌分离株由于其普遍存在的性质，常被认为是污染物，有时会导致诊断延迟。对于培养阴性的心内膜炎或棒状杆菌“污染”的患者，在微生物分离试验结果出来之前，应按患有棒状杆菌心内膜炎进行治疗。
