Chondroblastoma is a rare benign tumor of cartilage tissue accounting for less than 1% of all bone tumors. The epiphysis of long bones is the typical localization, often extending to the metaphysis. Metaphyseal, metaphysodiaphyseal or pure diaphyseal forms are exceptional. We report a case in a 15-year-old boy who presented a metaphyso-diaphyseal chondroblastoma of the distal portion of the left femur. The inaugural signs were pain and limited joint motion. We discuss the anatomic aspects and the clinical course of this rare tumor and present current knowledge of the histogenesis.
软骨母细胞瘤是一种罕见的软骨组织良性肿瘤，占所有骨肿瘤的比例不到1%。长骨的骨骺是其典型的发病部位，常延伸至干骺端。干骺端、干骺-骨干或单纯骨干型较为罕见。我们报告一例15岁男孩，其左股骨远端出现干骺-骨干型软骨母细胞瘤。首发症状为疼痛和关节活动受限。我们讨论了这种罕见肿瘤的解剖学特点和临床过程，并介绍了目前关于其组织发生的知识。
