The treatment of swollen inguinal lymph nodes varies depending on the specific cause, and the causes of swollen inguinal lymph nodes can be divided into two categories: benign diseases and malignant diseases. Benign diseases are most often seen in various infections or traumas of the lower extremities, lower abdomen, perineum and genitalia, where the main treatment is specific anti-infective treatment for these infections, such as anti-bacterial, anti-fungal and anti-tuberculosis treatment. Other causes of inguinal lymph node enlargement are malignant diseases, such as malignant tumors of the lower extremities, lower abdomen, perineum, and genitals, and possibly systemic hematologic tumors, such as lymphoma, which should be treated accordingly in order to solve the problem of inguinal lymph node enlargement.
