1/748. brain metastasis from prostatic carcinoma.

    Between 1959 and 1971 there were 91 patients with clinically diagnosed prostatic carcinoma who were autopsied at Roswell Park Memorial Institute. In four of these 91 (4.4%) intracerebral metastasis were found at autopsy, but only in one of these four was the diagnosis arrived at pre-mortem. This report describes the diagnosis and management of intracerebral metastasis from prostate carcinoma. It appears, on the basis of our initial experience, that the clinical diagnosis of this entity deserves more frequent consideration.

2/748. Intra-articular metastatic melanoma of the right knee.

    melanoma can metastasize to almost every organ and tissue. Although bone metastases have been reported frequently, the authors are aware of only a single report of intra-articular synovial metastasis. A case of metastatic melanoma, mimicking degenerative medial meniscal tear of the right knee, is presented. Further examination revealed asymptomatic metastases in the liver, subcutaneous tissue, and left trochanter minor. Arthroscopic examination revealed widespread synovial metastasis and a palliative arthroscopic synovectomy was performed.

3/748. Translocation of chromosomes 11 and 22 in choroidal metastatic Ewing sarcoma detected by fluorescent in situ hybridization.

    PURPOSE: To describe a patient with metastasis of Ewing sarcoma to the choroid and the molecular genetics of the tumor. methods: A 26-year-old woman with metastatic Ewing sarcoma developed large choroidal masses in the left eye and died 2 months later. autopsy of the eyes was performed. Dual-color fluorescent in situ hybridization was used to detect genetic alteration in the ocular tumor with EWS and FLI-1 probes. RESULTS: Histopathology confirmed choroidal metastatic Ewing sarcoma. Molecular analysis showed chromosomal translocation t(11;22)(q24;q12) or EWS/FLI-1 rearrangement in the malignant cells of the eye. CONCLUSIONS: Ewing sarcoma can rarely metastasize to the uvea. Molecular detection of the t(11;22)(q24;q12) translocation in Ewing sarcoma is valuable in the differential diagnosis of small round cell tumors.

4/748. Spontaneous remission of solitary bony metastasis after removal of the primary kidney adenocarcinoma.

    The second case of spontaneous remission of a biopsy-proved osseous metastasis from a renal carcinoma is reported. The unusual feature of the patient presenting with a right varicocele and no hematuria is extremely rare.

5/748. Bone metastases from bronchial carcinoid tumors. Two case-reports.

    Two case-reports of metastatic bone disease in patients with bronchial carcinoid tumors illustrate the diagnostic challenges raised by these slowly-growing malignancies of which the primary frequently escapes early identification. The first patient had the typical picture of a primary with a single bone metastasis. Unusual features in the second patient were the large number of bone metastases, involvement of distal skeletal sites, and elevation of serotonin and 5-hydroxyindoleacetic acid levels.

6/748. Lessons from an unusual case: malignancy associated hypercalcemia, pancreatitis and respiratory failure due to ARDS.

    A 37-year old woman, presenting with severe hypercalcaemia-associated pancreatitis with pseudocyst formation, was admitted to intensive care because she developed ARDS with respiratory failure. Skeletal metastasis from non-small cell bronchial carcinoma were subsequently diagnosed. After she developed arterial occlusion in the lower limb, supportive treatment was withdrawn. Severe pancreatitis is an exceedingly unusual presentation of non-small cell bronchial carcinoma. Concepts of diagnostic and therapeutic strategies in the context of suspected unusual pathology, and the concept of futility are briefly discussed.

7/748. Differential diagnosis of metastases in bone scans: chemotherapy induced bone necrosis.

    AIM: Influenced by the incorrect diagnosis of a bone metastasis caused by bone necrosis we evaluated reasons and frequency of bone necrosis in patients referred for bone scanning in follow-up of tumors. methods: Bone scans performed within two years on patients with primary bone tumors or tumors metastatic to bone were reviewed in respect to the final diagnosis bone necrosis. RESULTS: We found the cases of three young patients who presented the appearance of hot spots on bone scintigrams which were finally diagnosed as bone necrosis. In two cases the diagnosis was based on histological findings, in one case the diagnosis was made evident by follow-up. All the three patients had been treated by chemotherapy and presented no other reason for the development of bone necrosis. Enhanced tracer uptake in all sites decreased within eight weeks up to two years without therapy. CONCLUSION: Single and multiple hot spots after chemotherapy may be originated by bone necrosis but mimicry metastases.

8/748. 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.

9/748. Small mucosal carcinoma of the stomach with para-aortic lymph node metastasis: a case report and review of the literature.

    A 38-year-old woman presented with a mucosal gastric carcinoma measuring 0.7 x 0.5 cm and para-aortic lymph node metastasis. Radiographic and endoscopic studies showed a small depressed lesion on the anterior border of the gastric angle, which was classified as a type II c III lesion. Histological examination of the biopsy specimen revealed a signet-ring cell carcinoma. Distal gastrectomy with wide lymph node excision was performed. Detailed study of the resected specimen revealed that the tumour was limited to the mucosa, but metastasized to both the perigastric and para-aortic lymph nodes. The patient received adjuvant immunochemotherapy postoperatively. However, multiple bone metastases developed at 3 years and she died 4 years after the operation.

10/748. US and CT findings of multicentric leiomyosarcomatosis.

    This article presents a case of leiomyosarcomatosis with widespread lesions involving the soft tissues and the most unlikely organs such as thyroid and salivary glands, pancreas, ligamentum teres, bladder wall, and bones without lymph node or distant metastasis. The CT and US findings of this rare phenomenon are discussed with regard to the literature.
