We are unaware of any reports in the literature of pathologic coracoid process fractures and only one report of metastatic disease to the coracoid. Methods and Results In this case report we present two cases with metastatic breast carcinoma of the coracoid process one of which presented with a pathologic fracture of the coracoid. Conclusions An orthopaedic surgeon must be aware of the potential for metastatic disease to the coracoid as they may be the first medical provider to encounter evidence of malignant disease. Introduction The coracoid process of the scapula is a rare site of involvement for metastatic disease or for primary tumors. Bone metastases are common in patients with breast carcinoma with an incidence as high as 73 range 47-85 1 . The exact mechanism of metastases to bone remains unknown. We are unaware of any reports in the literature of pathologic coracoid process fractures and only one report of metastatic disease to the coracoid 2 . We present the cases of two patients with metastatic breast carcinoma of the coracoid process one of which presented with a pathologic fracture of the coracoid. We informed the patients or their families that the data concerning their cases would be submitted for publication and they consented. Case 1 A 40-year-old right-hand dominant female who had a known history of right breast carcinoma presented to our clinic for evaluation for open biopsy of a lesion at the base of the coracoid. Four months prior to clinic presentation she underwent right breast lumpectomy and lymph node dissection. Surgical .
