The authors present a case of primary intracranial extraosseous myxoid chondrosarcoma without any attachment to the cranium or the meninges. The clinical and radiological findings of the primary intraparenchymal tumor are described with a review of the literature concerning cranial and intracranial myxoid chondrosarcoma.

Our experience includes seven cases of ossifying fibroma. The condition also appears in the literature under diagnostic names such as congenital fibrous dysplasia, congenital osteitis fibrosa, congenital fibrous defect of the tibia, and osteofibrous dysplasia of the tibia and fibula. The lesions develop in childhood and are located in the diaphysis of the tibia, or fibula. Of seven patients, we performed wide excision with free vascularized fibular graft in five cases, wide resection of the distal one-third of the fibula in one case, and curettage and bone graft in one case. Two of the patients who had wide excision with free vascularized fibular graft had recurrence. One case of recurrence occurred where incomplete wide excision with free-vascularized fibular graft was performed because the lesion was too close to the distal epiphysis of the tibia. One of the patients who had curettage and bone graft also had recurrence. It was concluded that children who have an ossifying fibroma requiring surgery can safely be treated with wide excision with or without free-vascularized fibular graft.

An epithelioid hemangioma involving three contiguous bones in continuity has, to the best of our knowledge, not been reported in the literature. A case of a 48-year-old man presented with radiating pain to the lower thoracic region for two years. A radiograph and CT scan revealed both permeative osteolytic and multiple trabeculated lesions involving the left posterior part of the 10th rib as well as the 9th and 10th vertebral bodies in continuity and was misled as a malignant or infectious lesion. The histopathology and immuno-histochemistry of the lesion confirmed the diagnosis of an epithelioid hemangioma. The lesion was still stable as of three years after surgery.
