Giant fibrolipoma of the median nerve in the thenar eminence: Case report and literature review

Nerve fibrolipoma is a very rare benign tumor, corresponding to fibrofatty proliferation of the epineurium and perineurium, where most frequently, the median nerve is touched. We report the case of a 52-year-old patient who has a giant fibrolipoma of the thenar branch of the median nerve evolving at the level of the thenar eminence, an exceptional size and location for this disorder. Our case presents fibrolipoma of the median nerve in thenar eminence, a size and localization that has not been reported in the literature to our knowledge A good dissection makes it possible to obtain total resection without neurological after-effects.
