A 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 Wordsvacuum assisted closure, infection, instrumentation, spine

Synchronous Primary Multifocal Skeletal Chondrosarcoma of Extremity

“…M ultiple chondrosarcoma is commonly described in the setting of multiple enchondromatoses [12][13][14] . Secondary multiple chondrosarcoma (synchronous or metachronous) can develop in the setting of Ollier disease (multiple enchondromatoses).…”

Multicentric Chondrosarcoma Involving the Appendicular Skeleton: A Case Report and Literature Review

“…A more recent case of multicentric chondrosarcoma in a 40-year-old female patient described two non-contiguous chondrosarcomas, one originating in the left pelvic region and one originating in the right scalp, with no evidence of visceral or pulmonary metastases 11 . Our patient similarly did not show pulmonary metastasis.…”

“…Multicentric tumours are uncommon, given that they develop at the same time in more than one organ or site, but without a clonal relation 10 . Conventional chondrosarcomas rarely present with metastases, and it is rare to observe multicentric behaviour in malignant cartilage tumours 11 . Other than patients with mesenchymal chondrosarcomas, the greatest proportion of individuals with chondrosarcoma do not show multicentricity, including patients with multiple exostoses or with enchondromatosis 12 .…”
