A Rare Cause of Coccydynia: Sacrococcygeal Chondrosarcoma

Spinal chondrosarcomas are rare, with only some case series reported in the literature. Less than 10% of chondrosarcomas are localized in vertebrae, with the thoracic vertebrae being the most common site. Sacral localization is rare; however, the case reported in our study involved a unique instance of chondrosarcoma affecting the distal sacrum and first coccygeal vertebrae. The patient presented with coccydynia. In this case, the grade 2 tumoral lesion was resected with wide margins, without chemotherapy and radiotherapy, and no relapse was reported at the 6-month follow-up.
