Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Inflammation of lymphatic channels in subcutaneous tissue is commonly caused by spread of local bacterial infection; group A β-hemolytic streptococcal species are the most frequently implicated. Lymphangitis is characterized by red linear streaks extending, within 24 to 48 hours, from a primary site of infection (eg, abscess, cellulitis) to regional lymph nodes (eg, axilla, groin). The lymph nodes are often enlarged and tender. The differential diagnosis includes cellulitis, trauma, and superficial thrombophlebitis.
