本文报告40例(54个)邻皮质软骨瘤均经手术病理证实。重点对 X 线诊断价值进行讨论。认为该肿瘤是一种生长缓慢而特殊的软骨类良性肿瘤。在组织学上较常见的内生软骨瘤有更为密集的软骨细胞巢及较大细胞核。这些征象通常属侵袭性强或恶性肿瘤。这便是肿瘤在组织学上的特殊性和临床与病理的不一致性,X 线检查则能充分反映出该 This article reported that 40 cases (54) of adjacent cortical chondroma were confirmed by pathology. Focus on the diagnostic value of X-rays. It is thought that this tumor is a kind of benign tumor with slow growth and special cartilage. Histologically more common endochondromas have denser chondrocyte nests and larger nuclei. These signs are usually aggressive or malignant. This is the specificity of the histology of the tumor and the inconsistency between the clinical and pathological conditions. The X-ray examination can fully reflect the
