The presence of inguinal lymphnodes
may occur due to many clinical reasons. It may be an acute infection, a chronic infection or a neoplastic condition.
Lymphnodes have an inherent protective function in the body and enlarged lymphnodes signify the ability of the body to fight disease.
Coming to your son's condition, it would be important to know if he has pain and tenderness in the area. If it is associated with pain and is sudden in occurrence, it might be an acute infection and will subside on antibiotics.
If there is no pain and several other lymph nodes get enlarges in due course, associated with weight loss
and low grade fever
, a chronic infection or neoplastic condition should be ruled out. This can be done by a small needle aspiration test (FNAC).
Hope this helps.
