Lipome géant du troisieme doigt : à propos d’un cas

Median Nerve Compression in Carpal Tunnel Caused by a Giant Lipoma

“…Lipomas represent 16% of all mesenchymal tumors [4] and are frequently the first type of benign tumor to occur in limbs. Although they are predominantly localized on the lower limbs, their localization in the hand is particularly interesting because of their atypical expression there.…”

“…Lipomas of the hand principally occur in individuals between 50 and 60 years of age [3, 4]. Patients usually report progressive development of a soft, mobile, and painless tumefaction on one of their hands.…”

“…Its clinical expression is identified by the topography of the compression: carpal tunnel syndrome in the case of median nerve compression [3, 5], hypoesthesia of the half pulp in the case of digital collateral nerve compression [4], and ulnar hypoesthesia in the case of Guyon's canal compression [6]. Other localizations are more anecdotal: compression of the superficial sensory branch of the radial nerve in the anatomical snuffbox [2] or compression of the posterior interosseous nerve [7].…”
