Abstract：
Chondrosarcomas are rare malignant cartilaginous tumor affecting adult and elderly patient. Pelvic and long bones are the most common location. We differentiate conventional chondrosarcoma which arises do novo from preexisting normal bone (primary chondrosarcoma) or within a preexisting lesion such as enchondromas or osteochondromas (secondary chondrosarcoma), Other rare subtypes of chondrosarcoma include clear cell chondrosarcoma, dedifferentiated chondrosarcoma, and mesenchymal chondrosarcoma, which will be considered separately. Although there are diverse clinical presentations depending on the anatomic extend, radiographic features of chondrosarcoma are very characteristic comprising frequently a combination of bone expansion and heterogeneous calcifications. We report a case of a 56-year-old male suffering from fixed mass adhering to the right pubic bone. MRI views showed a lytic lesion of right superior pubic rami, surgical biopsy was in favor of chondrosarcomas, then an en bloc resection was performed following a Pfannenstiel approach without any recurrence after three years of follow-up.
摘要：
软骨肉瘤是罕见的恶性软骨肿瘤，影响成人和老年患者。骨盆和长骨是最常见的位置。我们区分了从先前存在的正常骨（原发性软骨肉瘤）或在先前存在的病变内，如软骨瘤或骨软骨瘤（继发性软骨肉瘤），软骨肉瘤的其他罕见亚型包括透明细胞软骨肉瘤，去分化软骨肉瘤,和间叶性软骨肉瘤，这将被单独考虑。尽管根据解剖范围有不同的临床表现，软骨肉瘤的影像学特征非常具有特征性，通常包括骨扩张和异质钙化的组合。我们报告了一例56岁的男性，其固定肿块粘附在右耻骨上。MRI显示右耻骨上支溶解性病变，手术活检有利于软骨肉瘤，随后在Pfannenstiel入路后进行整块切除术,随访3年后无任何复发.
