Orificial tuberculosis (OT), a rare skin condition in immunocompromised patients, can be difficult to diagnose. Polymerase chain reaction (PCR) offers a rapid method for detecting Mycobacterium tuberculosis, enabling earlier treatment.

Area of Science:

  • Immunology
  • Infectious Diseases
  • Dermatology

Background:

  • Orificial tuberculosis (OT) is an uncommon form of cutaneous tuberculosis typically affecting immunocompromised individuals.
  • Variable clinical presentations of OT can lead to delayed diagnosis.

Observation:

  • A case study of a 53-year-old patient with orificial tuberculosis and miliary dissemination of Mycobacterium tuberculosis to multiple organs including lungs, liver, bones, and skin.

Findings:

  • Diagnosis was confirmed using polymerase chain reaction (PCR) for Mycobacterium-specific gene amplification and subsequent culture.
  • PCR identified mycobacterial DNA within days, significantly faster than traditional culture methods which require weeks.

Implications:

  • Polymerase chain reaction (PCR) can significantly improve the accuracy and speed of diagnosing skin tuberculosis.
  • Early and accurate diagnosis through PCR facilitates prompt initiation of treatment for orificial tuberculosis.
