granulomatous mastitis
Etiology
In a case of granulomatous mastitis due to Corynebacterium kroppenstedtii, a strongly impaired neutrophil responses to Nod2 agonist and a single nucleotide polymorphism within the NOD2 gene (SNP13 [Leu1007fsinsC]) in a heterozygous state have been found. These findings provided a demonstration of impaired Nod2 function associated with corynebacterial infection. (#19641059#)
