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.
起源于肋骨的骨软骨瘤很罕见。它们表现为肋骨的骨性赘生物，可向胸外延伸至皮下平面，或向胸内生长压迫肺或纵隔结构。一名23岁男性患者自去年起出现乳房肿块的症状。临床检查时，可触及一个轮廓呈分叶状的坚硬骨性突起。胸部X线片和增强CT显示，右第四肋肋软骨交界处前侧有一个骨性赘生物，胸大肌向前移位。在出现乳房硬块时，骨软骨瘤应与其他胸壁肿瘤一起作为鉴别诊断的考虑对象。
