Skin tuberculosis with anergy

Last Updated: 2023-07-07

Author(s): Anzengruber F., Navarini A.

ICD11: -

Anergy means that the intradermal tuberculin test is negative.

The lack of cellular defence against M. tuberculosis can be due to several circumstances. Both a previous lack of contact with M. tuberculosis and a weakened immune defence can be decisive for the negative tuberculin test.

 

Examples:

  • Tuberculous primary complex.
  • Tuberculosis cutis miliaris disseminata.
  • Tuberculosis (miliaris) ulcerosa mucosae et cutis.
  • Tuberculosis fungosa serpiginosa.
