Purpose: To investigate the radiological and histopathological features of periosteal osteosarcoma. Materials and Methods: Seven cases of periosteal osteosarcoma, pathologically proven, were analyzed for the clinical, imaging and histological findings in combination with relevant literature. Results: Periosteal osteosarcoma was frequently found on tibia.

Purpose: To investigate the radiological and histopathological features of periosteal osteosarcoma. Materials and Methods: Seven cases of periosteal osteosarcoma, pathologically proven, were analyzed for the clinical, imaging and histological findings in combination with relevant literature. Results: Periosteal osteosarcoma was frequently found on tibia. On imaging, periosteal osteosarcoma appeared as a partially mineralized mass on the cortical surface of a long bone in the portion of the diaphysis or metaphysis. By the margin of tumor, periosteal reaction was revealed, and erosion of the underlying cortex was observed, while the medullary cavity remained intact. Histologically, periosteal osteosarcoma is a moderately differentiated chondroblastic osteosarcoma. Conclusion: Combination of imaging and pathological examinations is important for diagnosis of the periosteal osteosarcoma.

目的:探讨骨膜骨肉瘤的影像及组织病理学特点。材料和方法:收集7例经病理证实的骨膜骨肉瘤,结合有关文献对其影像及组织病理学表现进行分析和总结。结果:骨膜骨肉瘤好发于胫骨,影像学上表现为发生在长骨的骨干或相当于干骺部位置的骨表面肿块,内见局灶性骨化或/和钙化,边缘可见骨膜反应,肿瘤下骨皮质可受侵,但不侵犯骨髓腔。病理上类似于软骨母细胞型的骨肉瘤,中度异型性。结论:骨膜骨肉瘤在影像和组织病理学上都有一定特点,影像与病理相结合对做出正确诊断是很重要的。

Objective To report the clinical experience of treatment for periosteal osteosarcoma (PERI) and high grade surface osteosarcoma (HGS), which are two rare subtypes of osteosarcoma arising from the surface of bone. Methods The clinical, radiographic and histologic features of 5 cases with PERI and 4 cases with HGS were reviewed. The ages of the 5 patients with PERI(1 male and 4 females) ranged from 28 to 42 years (mean 35 years). Four of five patients with PERI had involvement of the upper tibial...

Objective To report the clinical experience of treatment for periosteal osteosarcoma (PERI) and high grade surface osteosarcoma (HGS), which are two rare subtypes of osteosarcoma arising from the surface of bone. Methods The clinical, radiographic and histologic features of 5 cases with PERI and 4 cases with HGS were reviewed. The ages of the 5 patients with PERI(1 male and 4 females) ranged from 28 to 42 years (mean 35 years). Four of five patients with PERI had involvement of the upper tibial shaft, the other one had the lesion situated on the lower femur. Of the 4 cases with HGS, 3 were male and 1 was female. The average age of the 4 patients with HGS was 19.25 years (ranged from 17 to 23 years). All cases with HGS had involvement over the distal femoral shaft. Results All patients with PERI received wide resection, of which four patients remained continuously disease free(ranged from 3 to 9 years, mean 5 years and 9 months). The remaining one has remained disease free for one year and three months after secondary amputation for local recurrence. Of the three patients with HGS who had received wide excision and effective chemotherapy initially, one survived for 1 year and 9 months after amputation for recurrence, one died with pulmonary metastasis in 2 years and 4 months after operation, and one had tumor free survival for 7 years. The remaining one died in three months after diagnostic biopsy. Conclusion PERI is a less aggressive tumor than conventional osteosarcoma. Simple wide resection is the treatment of choice. HGS is a rare subtype of surface osteosarcoma with a prognosis similar to that of conventional osteosarcoma. Wide excision and effective systemic chemotherapy are associated with better clinical results.

目的报告表面骨肉瘤的两种少见亚型,即骨膜骨肉瘤和高度恶性表面骨肉瘤的诊治经验。方法回顾 5例骨膜骨肉瘤和 4例高度恶性表面骨肉瘤患者的影像学和病理学特点,并对临床治疗结果进行分析。 5例骨膜骨肉瘤患者,男 1例,女 4例;年龄 28~ 42岁,平均 35岁;肿瘤位于胫骨上段者 4例,股骨下段者 1例。 4例高度恶性表面骨肉瘤患者,男 3例,女 1例;年龄 17~ 23岁,平均 19.25岁; 4例患者肿瘤均位于股骨下段。结果 5例骨膜骨肉瘤均予以广泛切除,除 1例因局部复发行截肢术,现无瘤生存 1年 3个月外,余 4例已无瘤生存 3~ 9年,平均 5年 9个月。 4例高度恶性表面骨肉瘤患者,虽经积极综合治疗,但仅 1例无瘤生存 7年; 1例术后 2年 5个月复发而截肢,现无瘤生存 1年 9个月; 1例于术后 2年 4个月死于肺转移;另 1例在确诊后 3个月死亡。结论骨膜骨肉瘤和高度恶性表面骨肉瘤各具鲜明的影像学和病理学特点,骨膜骨肉瘤恶性程度较低,应采用以局部广泛切除为主的手术治疗,预后相对较好;而高度恶性表面骨肉瘤的生物学行为则与经典的髓内骨肉瘤相似,预后较差,必须采用手术与化疗相结合的综合治疗方法。

Objective To analysis the distinct roentgenographic features of four subtypes of osteosarcoma arising on the surface of bone. Methods A retrospective review was performed on 18 patients of osteosarcoma arising on the surface of the bone confirmed by surgery and pathology. The patients were diagnosed as 8 cases of conventional parosteal osteosarcoma (c POS), 1 case of dedifferentiated parosteal osteosarcoma (dd POS), 5 periosteal osteosarcoma (PERI) and 4 high ...

Objective To analysis the distinct roentgenographic features of four subtypes of osteosarcoma arising on the surface of bone. Methods A retrospective review was performed on 18 patients of osteosarcoma arising on the surface of the bone confirmed by surgery and pathology. The patients were diagnosed as 8 cases of conventional parosteal osteosarcoma (c POS), 1 case of dedifferentiated parosteal osteosarcoma (dd POS), 5 periosteal osteosarcoma (PERI) and 4 high grade surface osteosarcoma (HGS) according to the classification system developed at the Mayo Clinic. Results Periosteal new bone formation was noticeably absent in all 8 patients of c POS. On plain roentgenogram,5 of 8 c POS presented as an uniformly dense mass. Six cases had a peculiar tendency to encircle the involved bone with a thin (2~3 mm) lucent zone between the tumor and the underlying cortex. The CT of 7 c POS showed high density osteoid mass. There was largely radioopaque mass with frequent areas of radiolucency on conventional film and CT scan in 1 patient of dd POS. The roentgenographic features of 5 PERI were mixed radiolucent mass on the cortical. The sunburst appearance of radiating spicules of mineralized tumor osteoid at right angles to the cortical bone was seen with CT in all 5 cases of PERI. Four HGS appeared as inhomogeneous mass on roentgenogram. CT detected scattering calcification in the 4 masses and angiography found focal hypervascularity in 2 HGS. Conclusion Four subtypes of surface osteosarcomas have distinct roentgenographic features respectively, which is helpful for diagnosing, treating and predicting outcome of the lesion.

目的 结合临床病理表现 ,重点探讨表面骨肉瘤各亚型的影像学特征。方法 对经手术和病理证实的 18例表面骨肉瘤进行回顾性分析。其中经典型皮质旁骨肉瘤 8例 ,去分化皮质旁骨肉瘤 1例 ,骨膜骨肉瘤 5例和高度恶性表面骨肉瘤 4例。重点描述各亚型的影像学表现。结果  8例经典型皮质旁骨肉瘤均未见骨膜反应 ,其中 5例X线呈均一致密的骨性肿块 ,6例肿瘤围绕骨表面生长 ,肿瘤与骨皮质间形成 2~ 3mm透亮的间隙 ;7例CT扫描示肿瘤呈高密度肿块。 1例去分化皮质旁骨肉瘤X线示其内密度不均。 5例骨膜骨肉瘤X线表现为放射状透亮软组织肿块 ,CT见肿瘤内骨小梁呈放射状垂直于骨皮质排列。 4例高度恶性表面骨肉瘤X线呈密度不均一的团块状影 ,CT示肿瘤内有散在不同程度的骨化 ;2例血管造影示区域性血管增多。结论 表面骨肉瘤 4种亚型的各自鲜明的影像学特征有助于早期明确诊断以及制定相应的治疗方案和评估预后 ,尤其是血管造影可以反映去分化皮质旁骨肉瘤和高度恶性表面骨肉瘤的高度恶性特征。
