Tandem bullet injury: an unusual variant of an unusual injury.

Epithelioid perineurioma: an unusual variant.

An unusual epithelioid variant of perineurioma of the groin occurring in a 53-year-old man is described. The lesion appeared to be associated with a femoral nerve branch.

Monteggia variant: an unusual presentation

Abstract Introduction Double injury patterns in the form of Monteggia or Galeazzi fracture dislocation represent a spectrum of forearm injuries which are severe and usually necessitate operative intervention. Association of ulnar dislocation with proximal radioulnar disruption with fracture of the radial shaft, without dislocation of radiohumeral joint, represents a rare and unusual double inju...
