title: Multiple lumps in the breast due to Mycobacterium fortuitum.
abstract: Although breast tissue is the most resistant to tuberculosis, its incidence is increasing worldwide. High incidence of breast tuberculosis is presumed in India. The rapidly growing nontubercular mycobacteria, such as Mycobacterium fortuitum and Mycobacterium chelonae, are of increasing clinical importance because infections due to these organisms are often hospital acquired. The true incidence of M. fortuitum is unknown but it has been estimated to be between 4 and 6 cases per one million people. It causes skin or soft tissue infections following trauma or surgery. Breast infection with M. fortuitum is very uncommon. The most common clinical presentation of breast tuberculosis is a painless lump. Multiple lumps are rarely reported. The culture and molecular studies are the keystone for differentiation of various mycobacterium species. We report one such case of a 25-year-old female presenting with multiple painless lumps due to M. fortuitum infection in the left breast.
