The neck contains a large number of lymph nodes, known as the cervical lymph nodes and many are superficial and easily palpable (can be felt by touch). A swollen neck lymph node is not uncommon and frequently occurs in children, even when there is no disease or obvious cause present. With age, the incidence of enlarged neck lymph nodes declines except when it is due to some pathology.

The most common cause for swollen neck (cervical) lymph nodes is an infection. While most incidents of cervical lymph node enlargement is self-limiting and resolves quickly, some may persist for a longer time and may need more active management. Amongst this group, the supraclavicular lymph nodes are of special significance. Their enlargement may be an ominous sign since it is most often associated with malignancy and careful assessment and investigation is indicated.

For this reason, swelling of the groin lymph nodes is an important clinical indication of pathology within the lower abdominal wall, legs, groin, buttocks, anus, perineum and external genitalia.

This can arise from a host of possible causes ranging from minor injuries to infections and even cancer. Apart from the armpit itself, disorders or diseases of surrounding organs may also cause axillary lymph node swelling.
