Pulmonary disease is common. Atypical mycobacteria can manifest cervical or submandibular involvement identical to TB, except the involvement is usually unilateral. Group B streptococcal cellulitis and adenitis may occur in infants younger than 2 months. Brucellosis may accompany chronic or intermittent lymphadenopathy. Yersinia enterocolitica may be associated with cervical lymphadenitis.
Salmonella infection can correspond with generalized adenopathy.
Bubonic plague is caused by Yersinia pestis . In cat-scratch disease, the site of the scratch determines if axillary, epitrochlear, supraclavicular, femoral, inguinal, or submaxillary lymph nodes are involved. The nodes are nontender, discrete, mobile, and moderately or greatly enlarged. Occasionally, tenderness, redness, warmth, and suppuration may occur. Infectious mononucleosis normally presents with discrete, firm, nontender lymph nodes.
