A CORYNEBACTERIUM SPECIES THAT SHOULD NOT BE MISTAKEN FOR SKIN FLORA!

Pdf Summary

The document discusses a case of granulomatous mastitis caused by Corynebacterium kroppenstedtii in a 24-year-old woman. The patient presented with breast pain and swelling, leading to incision and debridement of the infected area and a biopsy sent for bacterial culture. The report emphasizes the importance of correctly identifying C. kroppenstedtii, as it should not be mistaken for skin flora due to its association with granulomatous mastitis. This specific species typically grows on sheep blood agar, demonstrating a lipophilic nature. The patient's organism was identified using MALDI-TOF-MS and found to be susceptible to several antibiotics. Treatment included drainage of the abscess and a 12-week course of doxycycline. The text highlights the need for accurate identification of C. kroppenstedtii in breast specimens and proper antimicrobial susceptibility testing based on CLSI guidelines. Recommendations are provided regarding media for optimal growth, with additional details on the clinical presentation, treatment strategies, and laboratory identification methods. Further research is needed to optimize treatment strategies for this type of mastitis.
