บทคัดย่อ

Nontuberculous mycobacteria (NTM) are infrequently harmful to humans but their incidence increases in
immunocompromised host. There are 4 subtypes of NTM; among them M. marinum is the most common
pathogen to human. Clinical manifestation of NTM infection can mimic tuberculosis of skin. Therefore,
supportive evidences such as positive acid-fast bacilli smear, characteristic histopathological finding and
isolation of organism from special method of culture can help to make the definite diagnosis.
Cases of NTM skin infection were reported with varying skin manifestations. Even patients responsed
well with many antimicrobial agents and antituberculous drug, some difficult and recalcitrant cases have
partial response especially in M. chelonae infected-cases.
