Achromobacter is a genus of non-fermenting gram-negative bacteria, mainly isolated from the respiratory tract of people with cystic fibrosis, but recognized as the causal agent of different types of infections, especially in individuals and with chronic diseases and immune deficiency. Skin infections are very rare and not easy to manage also due to the intrinsic resistance to various antibiotics empirically used in the treatment of skin infections. In this short report, we intend to describe a rare case of Achromobacter denitrificans cellulitis with the result of an analysis of the cases described in the literature.
