Corynebacterium species, other than Corynebacterium diphteriae, are usually dismissed as contaminants when recovered from patient's samples. It is often difficult to decide whether these bacteria have clinical relevance or not. The Corynebacterium genus has been implicated in a wide variety of human infections. In this brief report, two cases of mastitis caused by Corynebacterium pyruviciproducens and Corynebacterium amycolatum are described in not breastfeeding women. These patients were immunocompetent with no evidence of ongoing risk factors for mastitis. This report seeks to give importance to this genus by always ranking cultures, starting with a thorough sample collection up until a complete evaluation of lab results and clinical presentation.
