An eight-year long case series follow-up study with pediatric bone cancer patients was conducted to compare the occurrence of adverse events associated with aprepitant with official sources of drug information (manufacturer's leaflet, clinical trials, and European Medicines Agency leaflet). All
A case of malignant lymphoma in the skull after head injury associated with whole bone metastasis is reported. The patient was a 66-year-old man who was admitted to Almeida Memorial Hospital because of headache and general fatigue 2 months after head injury. After admission tumors appear in the
Osteoblastoma is a rare benign bone tumor that usually arises in the vertebral column and long bones of young adults. Craniofacial involvement is extremely rare. To date, osteoblastoma of the frontal sinus has not been reported in the English literature. We report an osteoblastoma of both frontal
OBJECTIVE
Atlantoaxial tumors account for a substantial proportion of primary bone tumors in children. Before resection, surgeons must consider the complex regional anatomy, the potential for neurological compromise, craniocervical instability, and the question of tumor resectability in a growing
Intraosseous haemangioma constitutes less than ten percent of all primary bone neoplasms. Approximately 75 percent occur in the calvarium or vertebrae, with long bones, short tubular bones and ribs constituting the rest. We describe a 52-year-old woman who presented with left knee pain for 4-5 years
OBJECTIVE
Ewing's sarcomas are the second most common bone tumors in children and primary involvement of the cranium is uncommon. We analyzed retrospectively the data of ten patients with this rare subset of disease, who had been treated at our institute since 2005. Our aim was to assess the
BACKGROUND
Ewing sarcoma is a rare primary malignant bone tumor, which mainly affects children and adolescents. Calvarial bone involvement and its appearance in elderly patients are extremely rare.
METHODS
We presented a 68-year-old female patient with headache and right frontotemporal swelling.
Ewing's sarcoma, which accounts for 6 to 9% of malignant bone neoplasms in children, typically affects the trunk and long bones and less often affects the skull (i.e., maxilla, frontal, parietal, ethmoid, temporal bones). Adding to literature of five previously reported cases, we now describe the
OBJECTIVE
We analyzed the data for a series of 14 patients with primary Ewing's sarcomas of the cranium who were treated since 1985. Our aim was to assess the long-term outcomes and the selection of appropriate treatment methods.
METHODS
The patients were reviewed with respect to their clinical
Osteosarcoma, usually observed in long bones, is the second most frequent primitive malignant bone tumor after myeloma. The skull base is an exceptional localization. We report a case of skull base osteosarcoma managed in our department. A 23-year-old female was admitted for bilateral epistaxis,
Nasopharyngeal cancer (NPC) is the most common cancer among head and neck cancer that usually presented with unilateral neck mass. Unusual symptoms of NPC can lead us to diagnosis misleading and delayed definitive treatment. We present a case of NPC with bone metastasis in the shoulder. A
BACKGROUND
An osteoid osteoma (OO) is a benign bone neoplasm that typically occurs in the long bone diaphysis. We found only 8 cases of OOs of the skull base in the literature, and none of them were located in the clivus.
METHODS
A 44-year-old female patient with a history of 2 previous
BACKGROUND
Osteosarcoma is the second most common primary tumor of the skeletal system and the most common primary bone tumor. Usually occurring at the metaphysis of long bones, osteosarcomas are highly aggressive lesions that comprise osteoid-producing spindle cells. Craniofacial osteosarcomas
Benign osteoblastoma is an uncommon primary bone tumor frequently found in the vertebral column and long tubular bones, and rarely occurring in the calvarium. A case of a massive benign osteoblastoma of the suboccipital bone and foramen magnum region in a 9-year-old boy is reported. He presented
Hemangiomas are benign blood vessels tumors that represent less than 1% of all the bone neoplasms. Calvarial hemangiomas are mainly solitary lesions commonly located in the frontal and parietal bone; however, they may occur in any skull region. These tumors increase in size over a
