Pulmonary nodules due to Corynebacterium ulcerans

Abstract

A 53 year old male with symptoms of coughing for 6 months presented with bilateral multiple pulmonary nodules suggestive of metastatic disease. By surgical resection 4 out of 6 nodules were removed. Histopathological examination showed granulomatous necrotizing inflammation with growth of Corynebacterium ulcerans, which did not produce diphtheria toxin. The patient was treated with penicillin for 1 week. Follow-up for 2 yrs showed no sign of recurrence.
