[Frequency of perilymphadenitis in regional lymph nodes in carcinoma].

Intensity, frequency and extension of an inflammatory reaction of the lymph node capsule (perilymphadenitis) were investigated in nodes draining invasive ductal breast cancer and infiltrating adenocarcinoma of the large bowel. Occurrence of chronic perilymphadenitis was significantly higher in paracolic lymph nodes than in the axillary ones (p less than 0.05). Both paracolic and axillary lymph nodes developed perilymphadenitis more frequently when they were infiltrated by carcinoma (p less than 0.001). Frequency and extension of the inflammatory reaction of the capsule depended on the degree of carcinomatous infiltration.
