A 71
-year-old woman was admitted to hospital because of malaise and bloody stool. Laboratory findings consistently showed anemia (Hb 9.2 g/dl) and occult blood in the stool. Although barium series and endoscopy of the upper and lower intestinal tructs were carried out, there was no evidence of bleeding from the gastrointestinal tract 99mTcO4- scintigraphy, which was performed to exclude bleeding from Meckel's diverticulum, also did not locate a significant lesion. Angiographic imaging of the superior mesenteric arteries (SMA) was performed to exclude lesions such as small intestine tumors with extraluminal growth and vascular abnormalities such as A-V malformation and it revealed the round encasement of arteries in the peripheral SMA region, strongly suggestive of a small intestine
tumor
. Surgery was performed and an extraluminally protruding
tumor
was found in the small intestine. The excised
tumor
was 4 x 3 x 3.5 cm in size, are was diagnosed histologically as aberrant pancreas. The postoperative laboratory findings showed that the anemia had improved and occult blood was not detected in the stools. Although aberrant pancreas of the small intestine is a common benign tumor, it is a very unusual cause of bleeding from the alimentary tract.

A 71
-year-old patient had been suffering from pain-free obstructive jaundice for 8 weeks. Ultrasonography and computed tomography revealed an inhomogeneous mass (diameter 7 x 6 cm) in the head of the pancreas. In combination with a CA 19-9 of 329 U/l, the findings were highly suggestive of a pancreatic carcinoma. Endoscopic implantation of a pigtail drain into the dilated choledochal duct was performed. A partial duodenopancreatectomy (Whipple's procedure) became necessary because of continuous bleeding with hemodynamic disorders after endoscopic papillotomy. In the histopathological examination a low-grade malignant non-Hodgkin lymphoma of the pancreas (follicular centroblastic-centrocytic) was diagnosed. The differential diagnosis of primary pancreatic lymphoma from pancreatic carcinoma is usually impossible. Neither clinical nor laboratory nor imaging methods indicate to the correct diagnosis. In cases of relatively large pancreatic
tumor
masses and impression of the pancreatic duct without infiltration, a primary pancreatic lymphoma should be considered and a histological diagnosis by biopsy should be performed.

Plasma cell granuloma is mainly composed of reactive plasma cell proliferation, the origin of which is uncertain. Immunohistochemically, the plasma cells are characterized by a polyclonal nature, and must be distinguished from plasmacytoma which displays a monoclonal nature. This
tumor
is most commonly found in the lung and bronchus, but has rarely been described in the alimentary tract. We report herein a case of plasma cell granuloma of the transverse colon.
A 71
-year-old woman was admitted for lower abdominal pain with severe inflammation and anemia. Ultrasound examination and computed tomography showed an abdominal
tumor
. Barium enema revealed the
tumor
to be located in the transverse colon causing colonic obstruction. The resected
tumor
was spherical and mainly spread in the submucosal layer. Microscopically, the
tumor
consisted of severe infiltration of mature plasma cells within the spindle-shaped myofibroblasts. Immunohistochemical studies showed IgA, IgG, IgM, and kappa and lambda chains, and revealed a polyclonal nature of the plasma cells. Thus, a pathological diagnosis of plasma cell granuloma affecting the transverse colon was made. To the best of our knowledge, this is the first report of successful surgical resection of plasma cell granuloma of the colon.

We report herein an unusual case of a composite glandular-neuroendocrine carcinoma of the hilar bile duct.
A 71
-year-old Japanese woman was admitted to our hospital suffering from general fatigue, progressive jaundice, and a high fever. Computed tomography and angiography findings revealed a solid hypervascular mass in the hepatic hilus. Thus, a subsegmentectomy of the liver (S4, S5) and bile duct resection with lymph node dissection were performed. A
tumor
measuring 6.0 x 3.0 cm was found to be located in the bile duct of the hepatic hilus. Histologically, the
tumor
was composed of well-differentiated adenocarcinoma and small cell neuroendocrine carcinoma cells, with a histological transition between the two components. Grimelius' method revealed the presence of diffuse positive
tumor
cells in neuroendocrine carcinoma. The neuroendocrine tumor cells were also diffusely immunoreactive to chromogranin A. To the best of our knowledge, only 22 previous cases of composite glandular-neuroendocrine carcinoma in the biliary tract have been reported; however, this is the first case report of a clearly composite
tumor
of the hilar bile duct.

A 71
-year-old woman was admitted to our hospital with the complaint of lower abdominal pain. CT scan revealed a huge retroperitoneal mass. On laparotomy the
tumor
was found to have extensively invaded the retroperitoneum, and an incisional biopsy was performed. Histopathological diagnosis of the biopsied specimen demonstrated diffuse malignant lymphoma of the pleomorphic type. Six cycles of CHOP chemotherapy were very effective for complete remission. Our review of 18 cases in the Japanese literature showed that chemotherapy and radiotherapy were effective for retroperitoneal malignant lymphoma, so due care must be taken in opting for surgery.

Lymphoepithelioma-like carcinoma of the uterine cervix is very rare.
A 71
-year-old woman, who had cervical cancer stage IB, presented lymphoepithelioma-like carcinoma pathologically. The
neoplasm
revealed an undifferentiated, nonkeratinizing carcinoma, which contained prominent vesicular nucleoli histologically. Epstein-Barr virus (EBV) DNA and HPV-16 DNA were demonstrated in cancer cells when using polymerase chain reaction. The patient underwent a radical hysterectomy with bilateral pelvic lymph node dissection and bilateral salpingooophorectomy. Her postoperative course was uneventful. The literature and pathologic findings are reviewed and discussed.

Recent reports of cancers that produce colony-stimulating factors (CSF) and which are associated with leukocytosis indicate that most are granulocyte CSF-producing tumors.
A 71
-year-old man with metastatic chest wall tumors from large cell lung cancer with marked leukocytosis and eosinophilia was reported. His maximal leukocyte count was 48300/microliter with 37.5% eosinophils. Granulocyte-macrophage CSF (GM-CSF) activity detected by enzyme-linked immunosorbent assay (ELISA) in serum was 112 pg/ml (normal range < 2.0 pg/ml), but G-CSF was normal. Immunohistochemical detection of GM-CSF protein on a chest wall
tumor
sample was positive. Irradiation of the chest wall
tumor
was performed and the leukocyte count decreased temporally. However, he died of respiratory failure due to progressive tumor growth 56 days after admission. Based on these results it appears that autocrine production of GM-CSF is a possible cause of this leukemoid reaction.

A 71
-year-old man with inoperable intrathoracic esophageal cancer was treated by concurrent chemoradiation. A dose of 48 Gy (neck) and 60.6 Gy (mediastinum) and four courses of 5-FU (500 mg/day)-CDDP (50 mg/week) were delivered. The esophageal
tumor
and metastatic lymph nodes of the neck showed a complete response (CR) to the treatment, whereas paraaortic lymph nodes evidenced no change (NC). The patient is doing well without symptoms at 13 months after treatment. The chemoradiotherapy produced effective improvement and quality of life in this patient.

A 71
-year-old man was referred to us with diplopia, left peripheral facial nerve dysfunction, ataxic gait and dysesthesia of the extremities. Neurological examination revealed mild reduction of sensation to pinprick and light touch in the left dominant lower leg. His standing position was wide based, and he showed Romberg's sign. The patient also presented signs of left peripheral facial, bilateral abducent, and left oculomotor nerve dysfunction. Serum levels of CEA, CA 19-9, and proGRP were high. 67Gallium scintigraphy showed an accumulation of radioactivity at the hilum of the right lung, and the findings of bronchofiberscopy were compatible with the diagnosis of small cell lung cancer. Because the symptoms gradually worsened to the point that the patient could not move by himself, chemotherapy and radiotherapy were initiated 3 months after the onset of symptoms. While under chemotherapy, symptoms of neuropathy subsided and the patient was able to walk with the aid of a walking stick. Although all symptoms were indicative of carcinomatous neuropathy, no antineuronal antibodies were detected in the patient's serum by immunohistochemical techniques. However, because the lung cancer deteriorated gradually despite therapy, the patient died of respiratory failure. At autopsy,
tumor
metastases were found in the pericardium, left lung, both adrenal glands, right hilum lymph nodes, and mediasternal lymph nodes. No microscopic signs of metastases were found in the frontal, parietal, temporal, or occipital lobes, or in the basal ganglia, thalamus, midbrain, pons, cerebellar vermis and hemispheres, or upper medulla. Histopathologically, there was no degeneration of neuronal cell bodies in cerebellar or cervical dorsal root ganglia; however, almost total loss of myelinated fibers or variegated demyelination of myelinated fibers was observed in the anterior, lateral and posterior funiculus at both cervical segments of the spinal cord. The number of myelinated fibers was smaller in the 5th and 6th cervical left ventral roots. The reason why the patient's symptoms subsided during chemotherapy was probably a suppression of antineuronal antigen by chemotherapy and the repair of myelinated fibers.

A 71
-year-old woman with a solitary mucinous cystic
neoplasm
of the pancreatic tail complained of back pain. A laproscopic distal pancreatectomy was performed. Laparosonic coagulating shears (LCS) were employed for dissection of the surrounding tissue and transection of the pancreas. The main pancreatic duct was clipped. There was no evidence of bleeding or pancreatic leakage from the transection surface. Pathologic examination showed the
tumor
to be a mucinous cystadenoma. The postoperative course was uneventful. The LCS was effective in this application.
