A 61-year-old male was admitted to our hospital with a complaint of epigastric discomfort and back pain. Chronic pancreatitis was suspected after an abdominal US study. Therefore, an ERCP study was performed. Macroscopically, the papilla of Vater showed an irregular shaped swelling. An ERCP X-ray revealed no abnormal findings, but biopsied specimens from the papilla showed a well differentiated adenocarcinoma in the adenoma, so that a pancreatoduodenectomy was performed. The lesion was 15 x 9 x 6 mm in size, and a histological examination revealed that a minor portion of the tumor was a carcinoma while the major portion was an adenoma, and the invasion as being d0 panc0 n0.

A 50-year-old man had several months of progressively worse low-back pain associated with constitutional symptoms and a history of retroperitoneal tumor and bleeding duodenal ulcer. Initial evaluation suggested a lumbar spine tumor, but myelography confirmed the presence of an epidural abscess. Further evaluation revealed a duodeno-spinal fistula at the site of the previous duodenal ulcer, which proved to be the cause of the abscess.

A rare case of giant cell tumor originating in the rib is reported. A 23-year-old female was admitted because of a mass in the right chest wall, right back pain and bloody pleural effusion. Exploration revealed tumor originating from the 2nd or 3rd rib and invading the intercostal muscles and the right lung. We completely resected the tumor with chest wall and performed right pneumonectomy. The defect of the chest wall was reconstructed using polyester mesh covered with a Gore-tex soft tissue patch. The pathological diagnosis was a malignant giant cell tumor of the rib. She is now doing well and has had no recurrence for 18 months since the operation.

A case of extraskeletal Ewing's sarcoma arising in the chest wall of a 15-year-old male is reported in this paper. His complaint was chest and back pain. Physical examination and laboratory data disclosed no abnormality. Radiographs and computed tomography revealed chest wall tumor, and resection of the tumor with a portion of the eighth rib was performed. Histologically, there was no involvement of the rib at all. The tumor tissue was composed of solidly packed tumor cells which were uniform in size and shape. Individual tumor cells were small, round-shaped, and had scanty, ill-defined cytoplasm. The diastase-digested, PAS positive material was found in the cytoplasm. NSE (neuron specific enolase) was positive, but EMA (epithelial membrane antigen) LCA (leucocyte common antigen), and keratin were negative. With these results, we got a diagnosis of extraskeletal Ewing's sarcoma. Combination chemotherapy with vincristine, cyclophosphamide, adriamycin, actinomycin D was administered after operation, and there is no evidence of recurrence after 12 months of follow-up.

The treatment results in 59 patients with extradural spinal cord compression (ESCC) who were treated with irradiation between April 1987 and December 1988 were analyzed prospectively. Eighty percent of the patients presented with back pain, which preceded ESCC by an average of 6 weeks. The most common primary tumor was lung cancer (27% of cases), followed by prostate cancer and breast cancer. The prognostic significance of pretreatment motor function, degree of spinal cord block, radiosensitivity of tumor, and radiation dose schedule was determined with multivariate analysis. Only pretreatment motor function was found to be a significant factor in determining functional prognosis (P = .0058). Even with the increasing clinical awareness of ESCC, 78% of the patients in the current series were nonambulatory at presentation. Therefore, computed tomographic myelography or magnetic resonance imaging is recommended for patients with back pain and bone destruction at the site of the complaint if local radiation treatment is not planned.

Seminomatous germ cell tumors can arise as primary mediastinal malignancies in the mediastinum without involving the testis. The usual location is the superior mediastinum and histologically it is identical to the testicular seminoma. Here we report a case of extradural spinal cord tumor by primary mediastinal seminoma. The patient, 24 year old male, was evaluated for complaints of severe back pain associated with dysesthesia in lower limbs. He was operated as primary mediastinal seminoma when he was 21 years old. On admission, physical examination was unremarkable except for hypereflexia in lower extremities. The testis were normal. Chest radiography and computed tomography revealed a large mediastinal mass which invaded into the extradural space of the thoracic spine. He had a laminectomy of the thoracic spine and was treated by the radiation therapy and chemotherapy. This is the first report showing the neuroradiological findings of the extradural spinal cord tumor by primary mediastinal seminoma.

An extremely rare case of glomangiosarcoma (GS) occurring in a glomus tumor (GT) was evaluated ultrastructurally and histochemically. A man 65 years of age who was suffering from back pain underwent resection of a deep cutaneous nodule. Cells of a solid type GT showed numerous subplasmalemmal pinocytotic vesicles, thin filaments with scattered dense bodies, and thick external lamina, but negative desmin staining and a lack of glycogen. Similar findings also were observed in the GS, but were less obvious. The GS compressed the surrounding GT, exhibited many mitotic figures, prominent nucleoli, elongated nuclei and cytoplasm, and reacted more strongly to vimentin staining than the GT. The GT contained S-100 protein-positive Schwann cells, a few substance P-positive nerve fibers, and moderate numbers of infiltrating mast cells. None of these findings were observed in the GS. Results were consistent with the view that GS was transformed possibly from the GT, and that the good prognosis for GS may be due to its small size that may be related to the preexistence of a pain-causing GT.

Osteoblastoma of the spine is a rare but important cause of back pain in children. Ten children with this tumor were treated at the Alberta Children's or Foothills Hospital in Calgary, Alberta, between 1974 and 1986. There were seven boys and three girls; the age at diagnosis ranged from 2 to 16 years (average 11 years). In nine patients the tumor involved the posterior vertebral elements. One of the cervical lesions was in the vertebral body. Three patients had tumor in the extradural space. The commonest symptom was pain in the back and neck. Bone scans were positive in all patients, and computerized tomography scans were abnormal in the eight patients who had this imaging performed. Nine children were treated with laminectomy and removal of the abnormal pedicle and facet. Two patients required two operations each because of incomplete tumor excision at the first operation; in these, subsequent surgery gave complete relief of symptoms and radiographic studies showed no further tumor. In three other patients, tumor removal was incomplete, and one patient received postoperative radiation therapy. Bone grafts were placed in four patients. The diagnosis of benign osteoblastoma was confirmed histologically in nine patients. The outcome was good in all cases, with excellent pain relief. The follow-up period has varied from 8 to 153 months (average 66 months) and there have been no recurrences. Based on this experience, complete excision of spinal osteoblastomas is recommended whenever possible. However, a satisfactory outcome may be achieved following incomplete excision and bone grafting.

A solid phase immunoassay was used to evaluate the levels of serum and cerebrospinal fluid of alphafetoprotein and carcinoembryonic antigen in 33 individuals treated for backache and headache with no evidence of organic neurological disease, 19 patients with primary CNS tumor (benign or malignant) and 22 with CNS metastasis from a solid tumor. AFP serum and CSF levels were found in trace amounts or slightly elevated not exceeding normal limits in all groups. Patients with CNS metastasis were found to have statistically significant higher CEA levels (both in serum and CSF) than the control group, and the patients with primary brain tumors. Patients with leptomeningeal dissemination had statistically significantly higher CEA CSF levels than did patients with primary tumors, and patients with parenchymal metastasis.

Long acting D-Trp-6-luteinizing hormone-releasing hormone (LH-RH) microcapsules, 3.2 mg were given monthly, intramuscularly for a period of 6 months to 26 menstruating patients with symptomatic leiomyomas. The patients ages were 22 to 52 years. Five patients (20%) were infertile. Patient evaluation before initiation of treatment included endometrial biopsy, ultrasonic measurements of uterine and tumor volumes, and bone-mineral density. The patients were periodically followed hormonally and ultrasonographically. A statistically significant reduction in uterine and tumor volumes (maximal after 4 months of treatment) was observed in all the patients except one. Two patients discontinued the treatment after 2 months, preferring surgery. A nonsignificant decrease in the mean bone-mineral density was noted after completion of therapy. Minor side effects such as hot flushes, vaginal dryness, backache, vaginal spotting, and nervousness, were encountered frequently, disappearing within 6 weeks after the last injection. A significant increase in uterine and myoma volume was noted in all the patients at 3 months after treatment.
