Description: (Location & Drainage)

The obturator lymph nodes belong to the external iliac lymph node group. These nodes are located in the obturator canal and are associated with the obturator artery. However, these nodes are variable, and are often absent (present in 0–3.5%) (Földi et al., 2012).

The obturator lymph nodes drain the prostate in males, and the body of the uterus and cervix in females. They send efferent vessels to the medial external and common iliac lymph nodes. Lymph is then returned to the lateral aortic and caval lymph nodes of the left and right side, respectively.
