1/509. Mandibular metastasis in a patient with endometrial cancer.

    Gynecologic cancers metastatic to bone are a rare entity, and a metastasis to the mandible at initial presentation is even more infrequently seen. We present a case of a 71-year-old woman with stage IV endometrial cancer with a metastasis to the mandible, with no other sites of distal spread apparent. The endometrial tumor was a FIGO grade III adenocarcinoma. The pathologic evaluation of the mandibular lesion revealed poorly differentiated adenocarcinoma with focal squamous differentiation. She was treated with a total abdominal hysterectomy and bilateral salpingo-oophorectomy, radiation therapy to the mandible, and chemotherapy consisting of Taxol and carboplatin for six cycles. She had a complete response, but 10 months after the original diagnosis developed spinal cord compression and progressive disease in the pelvis. patients in good clinical condition with a single bone metastasis should be treated aggressively, as survival can be extended.

2/509. Hurthle cell carcinoma of the thyroid gland with extensive tumor necrosis: a case report.

    Hurthle cell neoplasm of the thyroid gland is rarely associated with tumor necrosis. We report a case of Hurthle cell carcinoma of the thyroid gland with extensive necrosis. An 82-year-old man had had a right neck mass for more than 10 years. Approximately two to three weeks before he was hospitalized, this neck mass became progressively enlarged. An 131I scan could not demonstrate the right lobe of the thyroid gland, while the contralateral lobe was unremarkable. A 99mTc-sestamibi scan showed increased uptake on the lesion side. Fine needle aspiration cytology showed necrosis with macrophages in the initial aspirate, and the secondary aspirate appeared suspicious for a Hurthle cell tumor. The patient had a total thyroidectomy, and the pathology proved to be Hurthle cell carcinoma with tumor necrosis.

3/509. Middle ear adenocarcinoma with intracranial extension. Case report.

    Middle ear adenocarcinoma is a very rare, locally invasive neoplasm assumed to arise from the middle ear mucosa. Although endolymphatic sac tumor (aggressive papillary middle ear tumor) and jugulotympanic paraganglioma may show brain invasion, intracranial extension of histologically confirmed middle ear adenocarcinoma has not been previously reported. The authors describe a 53-year-old man who suffered from otalgia and tinnitus for more than 10 years and from neurological deficits for 1 year due to a large temporal bone tumor that invaded the temporal lobe. A combined neurosurgical and otolaryngological resection was performed. Pathological analysis revealed a low-grade adenocarcinoma of a mixed epithelial-neuroendocrine phenotype, which showed a close histological similarity to, and topographical relationship with, middle ear epithelium. The authors conclude that middle ear adenocarcinoma belongs to the spectrum of extracranial tumors that have possible local extension to the brain.

4/509. radium-induced malignant tumors of the mastoid and paranasal sinuses.

    In the records of 5,058 persons with therapeutic or occupational exposure to radium, 21 patients with carcinoma of the mastoid and 11 with malignant tumors of the paranasal sinuses were identified. Tumor induction times were 21-50 years for mastoid tumors (median, 33) and 19-52 years for paranasal sinus tumors (median, 34). Dosimetric data are given for the patients whose body burdens of radium have been measured. We found a high proportion of mucoepidermoid carcinoma, comprising 38% of the mastoid and 36% of the paranasal sinus tumors. Three patients had antecedent bone sarcoma at 20, 11, and 5 years, respectively, and a bone sarcoma was discovered at autopsy in a fourth patient. Radiographic changes in the mastoid and paranasal sinuses were similar to those seen in nonradium malignant tumors. More than 800 known persons exposed to radium before 1930 and another group of unknown size who received radium water or injections of radium from physicians are still alive and at risk of developing malignant tumors of the mastoid and paranasal sinuses.

5/509. The uptake of gallium 67 in colonic macrophages.

    A case is presented in which a patient with a well-differentiated adenocarcinoma showed high gallium concentration in the segment with melanosis coli proximal to the obstruction. Although in this case the gallium was associated with an increased number of faecal pigment containing macrophages it is unlikely that macrophages are the main factor in tumour uptake of gallium compounds.

6/509. Malignancies in pediatric patients with ataxia telangiectasia.

    BACKGROUND: patients with ataxia telangiectasia (AT), known to have an inherent increased susceptibility to the development of cancer, may present with malignancies that are unusual for the patient's age, are often difficult to diagnose clinically and radiographically and respond poorly to conventional therapy. MATERIALS AND methods: We reviewed the clinical presentation and imaging studies of 12 AT patients who developed malignancies. RESULTS: Eight of the twelve patients developed non-Hodgkin's lymphoma (CNS, thorax, bone), two developed Hodgkin's disease, and two were diagnosed with gastrointestinal mucinous adenocarcinoma. CONCLUSION: The lymphomas were commonly extra nodal, and infiltrative rather than mass-like. The recognition of the tumors was often delayed due to confusion with the known infectious complications in AT patients.

7/509. A case of prostatic cancer metastasizing to the orbit.

    PURPOSE: We report on a case of prostatic cancer with multiple bone metastases, including right orbital involvement. methods/RESULTS: Hormonal treatment and local irradiation to the right orbit were performed. Subjective symptoms with exophthalmos and pain disappeared. CONCLUSIONS: We report on a case of prostatic cancer metastasizing to the right orbital bone.

8/509. Bone agent localization in hepatic metastases.

    We present the bone scintigrams of two patients, which demonstrate diffuse extraosseous uptake of a bone agent in metastatic masses in the liver, one from a primary lung tumor and one from a primary breast tumor. The bone imaging agent did not localize in the brain metastases in these patients. CTs of the abdomen in both patients showed massive metastases in the liver with multiple areas of tumor necrosis. The CT of the abdomen of the breast cancer patient showed multiple small hepatic calcifications. autopsy revealed massive tumor necrosis with calcifications in the enlarged liver. In routine bone scintigraphy, diffuse uptake of bone agents in the liver of a patient with a known malignancy should be considered suggestive of massive hepatic metastases.

9/509. Gingival metastasis from a prostate adenocarcinoma: report of a case.

    prostate cancer is the cause of 10% of cancer-related deaths in males in the united states. Metastases are found late in the course of the disease. Metastatic tumors of the oral cavity are rare, representing about 1% of oral tumors and affect jaws much more frequently than soft tissues. Metastatic prostate cancer tends to involve the bones of the axial skeleton. In a recent review, 22 cases of metastases to the jawbones from prostate cancer were found in 390 cases. On the other hand, only 1 case of a metastasis to the oral soft tissues was reported. The authors describe the second case of oral soft tissue metastasis from a prostate cancer. The metastatic lesion was located in the gingiva. Clinicians should be aware of oral soft tissue metastases since they can be the first sign of a not yet diagnosed malignant tumor and they can be very easily confused with several different benign lesions.

10/509. 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.
