Soft-tissue chondromas are benign, relatively rare lesions. The clinicopathologic and radiologic features in six cases are presented and the literature is reviewed. Five of six cases had calcifications. Peripheral curvilinear calcification was seen in two cases, multiple ringlike areas characteristic of cartilage in one, and discrete ossification in another. Histopathologically, they were diverse, ranging from an immature pattern with a preponderance of chondroblasts to a more mature form with chondrocytes. Although these lesions resemble a wide variety of other soft-tissue lesions, they can usually be differentiated by their small size, characteristic location in the extremities, the nature of their calcifications, and the histopathologic features. The importance of this lesion is that it is benign. It must be distinguished from more aggressive soft-tissue neoplasms such as soft-tissue chondrosarcoma so as to spare the patient unnecessary radical therapy.
软组织软骨瘤是一种良性但相对罕见的病变。本文呈现了6例病例的临床病理及放射学特征，并对相关文献进行了综述。6例中有5例出现钙化。2例可见外周曲线状钙化，1例有多个特征性的软骨环状区域，另1例有离散性骨化。组织病理学上，其表现多样，从不成熟型（以成软骨细胞为主）到更成熟型（含软骨细胞）。尽管这些病变类似于多种其他软组织病变，但通常可通过其小尺寸、在四肢的特征性位置、钙化性质及组织病理学特征加以鉴别。该病变的重要之处在于其为良性。必须将其与更具侵袭性的软组织肿瘤如软组织软骨肉瘤区分开来，以免患者接受不必要的根治性治疗。
