Common Language Description

A biopsy or excision of one or more superficial lymph nodes is performed using a needle. Superficial lymph nodes, such as those located in the cervical (neck), inguinal (groin), and axillary (armpit) regions, are situated close to the surface of the skin, allowing for access with minimal dissection of the overlying tissues. This procedure is particularly useful for diagnosing various conditions, including infections, malignancies, or other diseases affecting the lymphatic system. The lymph node targeted for biopsy is typically identified through palpation, which involves feeling the area to locate the node. Prior to the procedure, the skin over the lymph node is disinfected to reduce the risk of infection, and a local anesthetic is administered to minimize discomfort during the biopsy. The procedure may involve the use of imaging guidance, such as ultrasound, to ensure accurate placement of the needle. Once the needle is inserted into the lymph node, tissue samples are obtained and subsequently sent for laboratory analysis to provide further diagnostic information. This method is less invasive compared to open biopsies or excisions, making it a preferred option in many clinical scenarios.
