1/477. bone marrow examinations as final clue to diagnosis of hypercalcemia: report of two cases.

    Two young men with severe hypercalcemia in association with renal failure (one acute and one chronic) are reported in whom usual diagnostic tests failed to reveal an etiology, and the final diagnoses were given by bone marrow examinations. Early bone marrow examinations in specific patients with hypercalcemia of undetermined origin sometimes are vital as shown by our two patients.

2/477. Pelvic and lumbar metastasis detected by bone scintigraphy in malignant pleural mesothelioma.

    A case of a 43-year-old man suffering from pleural mesothelioma with distant bone metastasis is reported. The results of bone scintigraphy and NMR findings allowed the diagnosis. The current case describes a hematogenous metastasis to the pelvis and vertebral column from a malignant pleural mesothelioma that was detected initially by bone scintigraphy.

3/477. bone marrow metastases in disseminated alveolar rhabdomyosarcoma: case report with ultrastructural study and review.

    A case of desseminated alveolar rhabdomyosarcoma in an 18-year-old male with leuco-erythroblastic anaemia is described. Numerous bizarre malignant cells, including frequent multinucleated giant cells, were seen in bone marrow aspirates, and osteolytic lesions appeared late in the clinical course. The primary site of the neoplasm remained undertermined during life and also at necropsy, which revealed minute pulmonary metastases and extensive lymph nodal, pleural and skeletal deposits. The diagnosis was confirmed on necropsy tissue by ultrastructural examination which demonstrated numerous thin (5 nm) and thick (15 nm) intracytoplasmic filaments in tumour cells, sometimes organized in bundles; scattered dense Z-band-like bodies, and rod-shaped structures were also seen. The fine structure of the rhabdomyosarcoma in the present case is compared with previous ultrastructural studies. Elongated, thick intracytoplasmic filaments whose diameter corresponds to that of myosin myofilaments are strong evidence for rhabdomyoblastic differentiation and are considered to be the sine qua non of a positive electron microscopic diagnosis of rhabdomyosarcoma. Orgaized bundles of filaments and Z-band-like dense bodies are usually present, and rod-shaped structures are found infrequently, but none of these are necessary for the ultrastructural diagnosis.

4/477. Chronic renal failure causing brown tumors and myelopathy. Case report and review of pathophysiology and treatment.

    Brown tumors (osteoclastomas) are histologically benign lesions that are caused by primary or secondary hyperparathyroidism. Secondary hyperparathyroidism is a frequent complication of chronic renal failure. Skeletal brown tumors are relatively uncommon, and brown tumors that involve the spine are considered very rare. The authors present the case of a 37-year-old woman with systemic lupus erythematosus and hemodialysis-dependent anuric renal failure, in whom spinal cord compression developed due to a brown tumor and pathological fracture at T-9. The patient underwent transthoracic decompressive surgery and spinal reconstruction in which cadaveric femoral allograft and instrumentation were used. Brown tumors of the vertebral column require surgical treatment if medical therapy and parathyroidectomy fail to halt their progression or if acute neurological deterioration occurs. In patients with renal failure bone healing is delayed and there is an increased risk that healing will fail because the metabolic derangements can result in severe osteoporosis. Surgical reconstruction of the spine may require the use of augmentation with instrumentation and aggressive treatment of hyperparathyroidism to achieve successful outcomes.

5/477. A case of hepatocellular carcinoma with bone metastasis responding to radiotherapy after successful hepatectomy of primary lesion.

    Radical hepatectomy was carried out on a patient with hepatocellular carcinoma (HCC) located in segment VIII of the liver. The patient was a 56-year-old man who showed positive for hepatitis c antibody and negative for hepatitis b surface antigen. Six months after hepatectomy, a lumbar plane X-ray and computed tomography examination revealed bone metastases in the lumbar vertebrae. The patient was subsequently treated by radiation to the lumbar vertebrae in response to lumbago. The metastatic lesion has been well controlled by radiotherapy on an outpatient basis with no recurrence for 5 years and 3 months. The prognosis of patients with HCC with distant metastases is poor. It is believed that the long survival of this patient can be attributed to successful radiotherapy of the bone metastasis after hepatectomy and the lack of recurrence in the liver.

6/477. Occipital pain in osteoid osteoma of the atlas. A report of two cases.

    STUDY DESIGN: Two cases of occipital pain caused by an osteoid osteoma of the atlas are presented. OBJECTIVES: To describe the management of occipital pain in two young patients. SUMMARY OF BACKGROUND DATA: Osteoid osteoma is a benign lesion mostly affecting the long bones. A spinal location is uncommon. To the authors' knowledge, there are only five other reports of an osteoid osteoma located in the atlas. methods: Occipital headache, which was relieved by salicylates, was the major symptom reported by the two adolescents. In the first patient, a lesion of C1 was seen on plain radiographs. In the second patient, the diagnosis of osteoid osteoma was suggested by scintigraphic imaging and subsequently by computed tomography. RESULTS: Pain disappeared in both cases after surgical excision of the lesion. Histologic examination disclosed characteristic features of osteoid osteoma. CONCLUSIONS: Occipital pain in adolescents, which is relieved by aspirin, should raise suspicion about the possibility of an osteoid osteoma of the atlas. If standard cervical spine radiographs are negative, isotope scanning and computed tomography can help to establish the diagnosis. Complete excision eliminates the lesion and produces immediate relief for the patient.

7/477. Pathologic odontoid fracture and benign fibrous histiocytoma of bone.

    We present the case of a 44-year-old female patient, who sustained an odontoid fracture after a minor trauma (uncomplicated fall). The radiologic evaluation revealed a skeletal tumor of the second cervical vertebra together with a fracture line at the base of the odontoid process of the axis. The patient underwent surgery, the tumor was resected and the odontoid was stabilised using an autologous cortico-cancellous bone graft and a halo fixator. Histologic examination revealed benign fibrous histiocytoma, which is reported to be a very rare skeletal tumor.

8/477. A staff dialogue on caring for a cancer patient who commits suicide: psychosocial issues faced by patients, their families, and caregivers.

    Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery which provides hope to the patient, support to caregivers, and encourages the healing process. The Center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum during which caregivers discuss a specific cancer patient, reflect on the important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from their fellow staff members. The case presented was of a 31-year-old man who developed adenocarcinoma of the lung with painful bone metastases. His tumor was unresponsive to treatment and he subsequently committed suicide by shooting himself. The verbatim and subsequent discussion raised a number of issues. Staff were devastated by the violent way that he ended his life. They questioned whether more could have been done to prevent this outcome, yet acknowledged that it mirrored the way he had lived, and were able to discuss the values by which we live and die. Some, but not all, felt that the patient had the right to choose how and when to end his life.

9/477. osteoblastoma in lumbar vertebral body.

    We report a young man with low back pain suspected to have a disc protrusion. Imaging suggested a tumour of the dorsal portion of the fifth lumbar vertebral body. Operation suggested a giant-cell tumour and subsequent histology showed an osteoblastoma. All typical imaging features of osteoblastoma are demonstrated in this rather uncommon location. Contrast-enhancing bone-marrow oedema on MRI, with mild enhancement of the tumour, together with the CT appearances were the clues to the diagnosis.

10/477. Atypical presentation of vertebral bone metastasis from lung cancer.

    The authors describe a case of lung cancer in a 55-year-old man who complained of back pain. Initial isotopic bone scanning showed no abnormality, however, magnetic resonance (MRI) imaging revealed bone metastasis in thoracic vertebral bone. Even when there is no typical findings of metastasis in bone scintigraphy, MRI imaging would be useful if vertebral bone metastasis is suspected. MRI imaging is an important modality to evaluate extraosseous extension and marrow invasion of metastatic tumors.
