When vaccination is made in the leg, as shown in the plate, there is a nodular swelling in the groin or inguinal region. As these glands are connected with the pelvic lymphatics, we find the ovary on the vaccinated side congested and sensitive. In some cases the inguinal adenitis is so marked, the patient is unable to work for days. It takes time to reduce this lymphatic blockage and the leg is often swollen, and in some instances turns black. The lymphatic blockage may extend down to the foot.
Suppuration follows, and a running sore persists for months.
We are now confronted with the blockage of the mesenteric nodes and interference with drainage in the thoracic duct. The plate shows the abdominal nodes and the duct leading up to the neck. Another plate shows the lymphatics of the pelvic region. The possibility of nodular enlargement in the axillary and cervical regions, including the tonsillary area, is plainly shown. The lymphatics of the entire arm may become involved, and spread to the pectoral region.
