Mycobacterium fortuitum Infection at Umbilical Hernioplasty Site

Non Tuberculous Mycobacteria (NTM) are a group of rapidly growing mycobacteria and are generally considered to be of low virulence. Of late, there has been an increase in incidence of infections due to these organisms. Among them, Mycobacterium fortuitum, M. chelonae and M. abscessus are the common species which have been identified. Though they are occasionally implicated in pulmonary infections, NTM are very commonly associated with cutaneous infections, especially surgical site infections. Identification of NTM infection at such sites should be suspected when there is delayed healing of the wound. Histopathological Examination (HPE) of the wound site may reveal a classical picture of granulomas, epithelioid cells and giant cells which may lead to a suspicion of tuberculosis. It is important to perform mycobacterial culture and sensitivity testing of the wound tissue as this helps to differentiate tuberculous and non tuberculous infections. Here, we present a case of a patient who underwent mesh hernioplasty for umbilical hernia and was diagnosed with M. fortuitum infection at the site of umbilical hernioplasty.
