Tendinitis of the pectoralis major insertion with humeral lesions. A report of two cases

Abstract

Two patients presented with pain in the arm and a radiographic lesion of the upper humerus which warranted surgical exploration and excision biopsy. In both cases the pathology was inflammatory and involved the insertion of pectoralis major. Tendinitis of the pectoralis major with an associated lesion of the humerus has not previously been described.
