We present an adult case of the chest wall tumor, which was accidentally pointed out by a medical checkup. Surgical resection was performed for the tumor, as preoperative biopsy of the tumor suggested the possibility of malignancy. Postoperative pathological examination revealed the diagnosis of mesenchymal hamartoma of the chest wall, which usually occurs in early infancy and childhood. Immunohistochemical staining for Sox9 was positive for chondrocytes and partially positive for spindle tumor cells. It is considered that the present case was not pointed out until the patient became an adult, because the tumor was relatively small and thus asymptomatic.
我们报告一例成人胸壁肿瘤病例，该病例是在一次体检中偶然被发现的。由于肿瘤的术前活检提示有恶性可能，因此对该肿瘤进行了手术切除。术后病理检查显示诊断为胸壁间叶性错构瘤，这种肿瘤通常发生在婴儿早期和儿童期。Sox9免疫组化染色显示软骨细胞呈阳性，梭形肿瘤细胞呈部分阳性。据认为，本病例直到患者成年才被发现，是因为肿瘤相对较小，因此没有症状。
