Superficial Lymphatic Drainage of Anterior Abdominal Wall - NEET PG/FMGE/USMLE The cutaneous (superficial) lymphatic vessels of the anterior abdominal wall play a vital role in draining the skin and subcutaneous tissue, and follow a segmental and region-specific pattern 📍. These vessels accompany the superficial veins, particularly the superficial epigastric and thoracoepigastric veins, and their drainage pathways are divided by an important anatomical landmark — the transumbilical plane, which runs horizontally through the umbilicus 🧠. • Above the umbilicus, the superficial lymphatic vessels drain superiorly and laterally into the anterior axillary (pectoral group of axillary) lymph nodes. This includes lymph from the epigastric and hypochondriac regions. These axillary nodes are also shared with the lymphatics of the breast and upper thoracic wall, making it clinically important in cases like mastitis, breast cancer metastasis, or upper abdominal infections 🩺. • Below the umbilicus, the lymphatic vessels drain inferiorly into the superficial inguinal lymph nodes, especially the horizontal group, which lies just below the inguinal ligament. This territory includes lymph from the hypogastric, umbilical (infraumbilical), inguinal, and pubic regions. These lymph nodes are easily palpable and are frequently involved in infections or malignancies involving the lower abdominal wall, perineum, lower limb, and external genitalia 🦵. This superficial drainage pattern does not involve deep structures, which are instead drained by deep lymphatic vessels accompanying arteries and draining into external iliac, common iliac, and para-aortic lymph nodes. However, superficial lymphatics often serve as early indicators in systemic diseases like lymphoma, metastatic spread, or tuberculosis 🧬. Understanding this lymphatic drainage pattern is key in clinical examination, palpation of lymph nodes, surgical oncology, and interpreting imaging of lymphadenopathy. #LymphaticDrainage #AnteriorAbdominalWall #SuperficialLymphatics #NEETPG #FMGE #USMLE #ClinicalAnatomy #SurgicalAnatomy #AxillaryNodes #InguinalNodes #SurfaceAnatomy #LymphNodePalpation
