Cutaneous Metastasis of Chondrosarcoma: A case report with literature review

The metastasis secondary to chondrosarcoma to respiratory system is a common finding; however metastasis to other organs such as skin or bones is much less common. In the current report, we described a case with the history of chondrosarcoma of the mandible that recently referred with the scalp skin metastatic lesions. Our report was specified to a female patient that its secondary metastasis occurred only four months after initial tumor diagnosis. More interestingly, among all baseline laboratory parameters, only inflammatory biomarkers raised as the nonspecific diagnostic indices. In fact, the accurate diagnosis of metastasis to bone following chondrosarcoma may be delayed and even may be masked with early inflammatory reactions. In total, in all patients who suffered chondrosarcoma, early metastasis to skin or bones should be considered especially if raising inflammatory indices.
