Abstract

Osteochondroma arising from the rib is rare. They arise as bony outgrowths from the rib and extend either extrathoracically into the subcutaneous plane or intrathoracically compressing the lung or mediastinal structures. A 23-year-old male patient presented with complaints of breast lump since last year. On clinical examination, a hard bony projection with lobulated contour was palpable. Chest radiograph and contrast-enhanced CT showed a bony outgrowth arising from the anterior aspect of costochondral junction of the right fourth rib with displacement of pectoralis major muscle anteriorly. Osteochondroma should be considered as a differential diagnosis in the presentation of hard lump in the breast along with other chest wall tumors.

갈비뼈에서 발생하는 골연골종은 드물다. 골연골종은 갈비뼈에서 자라서 흉부 밖으로는 피하로 확장되거나 흉부 안으로는 폐 또는 종격동 구조물들을 압박한다. 23세 남자 환자가 작년부터 만져지는 유방 덩이를 주소로 내원했다. 임상 검사에서 소엽 모양의 단단한 뼈 돌기로 촉진되었다. 흉부 영상과 조영증강 CT에서 오른쪽 4번째 갈비뼈의 갈비뼈연골접합부의 앞쪽에 뼈의 과성장이 보였고 대흉근을 밀고 있었다. 유방의 단단한 덩이를 주소로 온 경우 다른 흉곽종양과 함께 골연골종이 감별진단에 포함되어야 한다.
