Which of the following cutaneous TB variants is considered the most common form in India and shows the highest bacterial load among all cutaneous TB types?
- A Lupus vulgaris ✓
- B Scrofuloderma
- C Tuberculosis verrucosa cutis
- D Orificial tuberculosis
Correct answer: A. Lupus vulgaris
Explanation
Lupus vulgaris is the most common form of cutaneous tuberculosis in India, occurring as a result of haematogenous spread or direct extension in patients with moderate cell-mediated immunity. While it has higher bacillary load than tuberculosis verrucosa cutis (which has the best CMI), orificial TB (occurring around orifices in patients with advanced systemic TB) has the highest bacterial load among all cutaneous TB forms due to the severely immunocompromised state.
