Area of Science:

  • Dermatology
  • Infectious Diseases
  • Microbiology

Background:

  • Cutaneous tuberculosis (skin TB) presents diverse clinical manifestations.
  • Understanding the epidemiology and classification of skin TB is crucial for diagnosis and treatment.
  • Ga-Rankuwa Hospital serves a population where tuberculosis is endemic.

Purpose of the Study:

  • To review the experience with cutaneous tuberculosis at Ga-Rankuwa Hospital over a 12-year period.
  • To identify the most common forms of skin TB encountered.
  • To discuss the classification and pathogenetic mechanisms of observed cases.

Main Methods:

  • Retrospective review of 92 patient records with a diagnosis of cutaneous tuberculosis.
  • Analysis of case types, including true infections and tuberculids.
  • Classification of presentations based on established dermatological criteria.

Main Results:

  • A total of 92 cases of cutaneous tuberculosis were identified over 12 years.
  • Lupus vulgaris was the most frequently observed true cutaneous TB infection.
  • Papulonecrotic tuberculid was the most common form of tuberculid encountered.
  • Several cases presented with features that were difficult to classify.

Conclusions:

  • The study highlights the varied spectrum of cutaneous tuberculosis seen at Ga-Rankuwa Hospital.
  • Lupus vulgaris and papulonecrotic tuberculid represent significant forms of skin TB in this setting.
  • Further research into classification and pathogenesis of challenging cases is warranted.
