title: Disseminated Mycobacterium avium Complex With Cutaneous Lesions.
abstract: BACKGROUND
  Although most commonly encountered in patients with human immunodeficiency virus infection, disseminated Mycobacterium avium complex (MAC) is becoming more common in patients receiving immunosuppressive medications. Disseminated MAC with skin lesions may occur, and several presentations have been reported, including panniculitis, cutaneous granulomas, pustules, ulcerations, and erythematous skin lesions.
  
  
  OBJECTIVE
  The objective of this report is to describe an unusual presentation of MAC that is unlikely to be encountered frequently in the outpatient dermatology setting, especially in a patient without human immunodeficiency virus infection.
  
  
  METHODS
  The authors present a case of disseminated MAC infection with cutaneous manifestations in an iatrogenically immunocompromised patient.
  
  
  CONCLUSIONS
  Diagnosis of MAC infection is challenging given the varied clinical presentations and the difficulty in culturing MAC. In addition, the acid-fast stain is nonspecific. Clinicians should remember to consider MAC infection in patients with acid-fast-positive skin lesions, as the selection of appropriate antibiotic therapy is species specific.
