- TB causes up to 43% of peripheral lymphadenopathy in the developing world [1]
- Most cases occur in the setting of reactivation of latent infection
- In the US, more common amoung Asian Pacific Islanders and in females
Clinical Features
- Enlarging, painless, red, firm, mass, most commonly in the anterior or posterior cervical chain
- Can be complicated by ulceration, fistula, or abscess formation
- Systemic signs and symptoms are uncommon, except in HIV patients (in whom lymphadenitis is usually generalized)

- Lymphoma
- Metastatic cancer
- Fungal disease
- Cat-scratch disease
