Hard bumps at the root of the thigh may be lipomas, sebaceous cysts, soft tissue tumors, femoral hernias, inguinal hernias, and enlarged lymph nodes. Among them, the enlarged lymph nodes are in the inguinal region, and because the lymph nodes in the normal inguinal region are larger, they can usually be touched after the patient lies flat. If it is a normal lymph node, the texture is tougher, the boundary is clear, and there is no pain when pressed. If the mass at the base of the patient’s thigh is larger and has a very hard texture, it may be a soft tissue tumor, and if the mass is large, fixation may occur. If necessary, a CT scan is performed and then surgical excision is performed. After excision, the mass is sent for pathological examination for further clarification. If the patient has an embedded femoral hernia, which also manifests as a hard mass at the root of the thigh, the location of the mass is lateral to the pubic symphysis, the pain is very pronounced, and it is difficult to be returned into the abdominal cavity, emergency surgery is usually required.
