Rare presentation of metachronous multicentric pelvic and extracranial chondrosarcoma : a case report.

ABSTRACT: Conventional chondrosarcomas rarely metastasize and it is extremely unusual to see multicentric- behaviour in malignant cartilage tumour. We report a 40 year old lady with presentation of two non-contiguous metachronous foci of low to intermediate grade of chondrosarcoma over left pelvic bone and right scalp respectively in the absence of pulmonary or visceral metastasis. KEY WORDS: vacuum assisted closure, infection, instrumentation, spine.
