Isolated Skull Metastasis of Ewing’s Sarcoma in a Child

Ewing’s sarcoma (ES) is a rare primary malignant bone tumor usually occurring in children and young adults. It most often affects long bones and pelvis. Metastatic lesions usually occur in lung, bone and the bone marrow. Central nervous system involvement is rare and it most frequently presents with other evidence of tumor recurrence. We present a case of isolated metastasis of ES involving the parietal bone in a 10-year old boy. To our knowledge, three other cases of skull metastasis of ES have been published previously. All of them presented other systemic metastases at the same time. The surgical indication for skull metastasis of ES depends on its location and general condition. Resection of solitary skull metastasis of ES should be as radical as possible, followed by systemic chemotherapy.
