Classification of skin tuberculosis
Tuberculosis of the skin has different clinical and pathological features depending on the patient’s resistance and age.
- Patients with good resistance
– Lupus vulgaris
Scrofuloderma.
– Tuberculosis verruca cutis
– Tuberculids.
Exanthematous lesions
– Tuberculosis miliaris disseminata
– Lupus miliaris disseminatus fasciei
– Papulonecrotic Tuberculids
– Lichen Scrofuloderma
Patients with absent or poor resistance :
– Miliary tuberculosis.
– Primary tuberculous complex
– Erythema migran is associated with lyme borreliosis.

TB of skin:
- Lupus vulgaris:
– Skin TB without underlying active focus
– MC type of cutaneous TB
- Scrofuloderma:
– Skin TB secondary to underlying structure (joint, lymph node)
- Tuberculosis verrucosa cutis: It is a post-primary TB with good resistance
