Which subtype of cutaneous tuberculosis represents a high bacterial load state (paucity of immunity) and is analogous to lepromatous leprosy in the spectrum concept?
- A Miliary tuberculosis of skin ✓
- B Lupus vulgaris
- C Scrofuloderma
- D Tuberculosis cutis orificialis
Correct answer: A. Miliary tuberculosis of skin
Explanation
Miliary tuberculosis of skin occurs in immunocompromised/severely debilitated patients with bacteremic dissemination from visceral TB — analogous to lepromatous leprosy in its high bacillary load and poor host immunity. Scrofuloderma is direct extension from underlying TB lymphadenitis/bone (not a bacteremic form). Lupus vulgaris and tuberculosis verrucosa cutis represent high-immunity forms. Tuberculosis cutis orificialis appears around natural orifices in patients with terminal visceral TB.
