Child of school age with complaints of painful mass in the groin were taken to the Children's City Clinical Hospital and from the ED sent to an ultrasound scan. On ultrasound in the projection of complaints in the inguinal-femoral region, there is a group of lymph nodes with a fuzzy contour and, presumably, foci of destruction (abscesses) and with edema of the surrounding subcutaneous fat.
As I understand it, the clinicians decided to send the patient to the oncologist.
