Unusual case of the saphenous plexus in the thigh and why we should have borne this variation in mind.

Detailed knowledge of the anatomy and different variations of the saphenous nerve could be of great importance not only to anatomists but also to clinicians. There are very few studies of saphenous nerve morphology in thigh. Most of the reported variations of this nerve concern the infrapatellar branch. In contrast, a saphenous plexus has been described in only one case. Herein, we present an unusual case of unilateral saphenous plexus formation in the right thigh found during routine anatomical dissection of a 69-year-old male Caucasian cadaver. We also present a brief discussion of the saphenous plexus and emphasize its potential clinical implications.
