Enneking type III resection of pubic chondrosarcoma: A case report

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.
