preg patients
weeks of gestation
exposure to infections
pets in household: cat feces
immunization status
older adults
autoimmune disease
recent infection or traume to nodes
delayed healing
immunization status
lymphadenopathy
enlarged lymph nodes
lymphadenitis
inflamed and enlarged lymph nodes
lymphangitis
inflammation of the lymphatics that drain an area of infection; tender erythematous streaks extend proximally from the infected area
- regional nodes may also be tender
lymphedema
edematous swelling due to excess accumulation of lymph fluid in tissues caused by inadequate lymph drainage
lymphangioma
congenital malformation of dilated lymphatics
shotty nodes
small non-tender nodes that feel like BB’s or buckshot under the skin
fluctuant nodes
wavelike motion that is felt when the node is palpated
matted nodes
group of nodes that feel connected and seem to move as a unit
hard, fixed, painless node
suggests malignant process
- usually rapid enlargement
tender node
more likely an inflammatory process
virchow node
palpable supraclavicular node on left
- clue to thoracic or abdominal malignancy
slow nodal enlargement suggests
benign process
