Zeus Mala, Omar Ksiks, Hajar Hamadi, Lamia Benantar, Khalid Aniba
TL;DR
A rare case of chondrosarcoma in the cranial vault is reported in a 75-year-old man who presented with headaches and a scalp outgrowth.
Contribution
This paper presents a rare case of primary chondrosarcoma localized in the cranial vault.
Findings
The tumor was a grade I chondrosarcoma located at the parietal suture.
The mass was successfully removed via en bloc surgical resection.
CT imaging showed a cystic mass eroding the parietal bone.
Abstract
Chondrosarcomas are malignant cartilaginous tumors that usually affect the pelvic bone and long bones. Primary chondrosarcomas of the skull are rare, with the cranial vault being an even more unusual localization. We report a case of a 75-year-old man presenting with headaches and outgrowth of the parietal scalp. CT scan of the head showed an extracranial cystic well-rounded mass originating at the parietal suture and eroding through the adjacent parietal bone. The patient underwent an en bloc surgical resection of the mass, and histological examination confirmed a grade I chondrosarcoma.
