Severe complications such as meningoencephalitis are quite rare in the setting of mumps infection. We report here on a 24-year-old soldier with a past history of MMR vaccination who was admitted because of aseptic meningitis. His mental status rapidly deteriorated and swelling of both parotid glands was observed. The MR findings revealed discrete lesions in the brainstem and thalamus. He barely recovered within 2 months. Among the adults with failure to acquire immunity despite MMR vaccination, institutional crowding can lead to cases of potentially fatal CNS complication such as mumps meningoencephalitis.

Hantaviruses cause two forms of human disease: hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome. Hantavirus infection can occur in pregnant women and it can have an influence on the maternal and fetal outcomes, although this is a rare finding even in endemic areas. We describe here a recent case of HFRS complicating pregnancy.

Essential thrombocythemia (ET) is a clonal disorder of myeloid stem cells that causes thrombocytosis. As a result, ET can lead to vascular thrombosis and tissue ischemia; the association of coronary artery abnormalities such as myocardial infarction or unstable angina is rare. Here we describe a 45-year-old male patient with essential thrombocythemia who presented with unstable angina. Elective coronary angiography showed total occlusion of mid right coronary artery and mid left anterior descending coronary artery. ET was confirmed by a bone marrow biopsy; treatment was started with antiplatelet therapy including aspirin and clopidogrel along with cytostatic therapy with hydroxyurea and anagrelide. After the initiation of the treatment, the platelet count decreased to 20 s 10(4)/microliter. In addition, percutaneous coronary angioplasty was successfully performed with stent placement at the right coronary artery without hemorrhagic or thrombotic complications.

Composite adrenal medullary tumors, composed of both pheochromocytoma and ganglioneuroma, are extremely rare, as are pheochromocytomas masquerading as acute relapsing pancreatitis. We recently experienced a case of a 48-year-old male with both these phenomena. The patient complained of an acute onset of intense abdominal discomfort. At the same time, pancreatic enzymes were increased in concentration. An abdominal computed tomographic scan revealed an enlarged pancreas and a 3-cm left adrenal incidentaloma. Biochemical and 131I-MIBG scintigraphic findings were compatible with a pheochromocytoma. Yet, he had no clinical manifestations suggesting pheochromocytoma. An adrenalectomy was performed and a composite adrenal medullary tumor of pheochromocytoma and ganglioneuroma was confirmed during a pathologic examination. This case illustrates two points: 1) acute abdominal intense discomfort and hyperamylasemia may be unusual presentations of pheochromocytomas; and 2) the possibility of the pheochromocytoma, albeit rare, should be considered when a relapsing pancreatitis of uncertain etiology develops.

Eosinophilic myocarditis usually results from myocardial damage as a result of drugs or parasites, and is generally associated with increased peripheral eosinophil count. This form of myocarditis is difficult to diagnose clinically. A 25 year-old previously healthy woman was transferred from a local clinic because of hypotension and dyspnea with sudden cardiogenic shock after a three day history of gastrointestinal illness. Echocardiography revealed concentric left ventricular wall thickening with moderate pericardial effusion. Biopsy of endomyocardial tissue from the right ventricle showed diffuse infiltration of inflammatory cells, mostly eosinophils, even though the patient had a peripheral eosinophil count that was normal at the time of biopsy. The patient was treated with corticosteroids for the symptoms of pericarditis, and she recovered without cardiac sequelae, clinically and echocardiographically. We here report a case of acute eosinophilic myopericarditis, with cardiogenic shock, diagnosed by endomyocardial biopsy with normal peripheral eosinophil count at the time of biopsy, and complete recovery without sequelae.

Primary lung cancer frequently metastasizes to distant organs. The pancreas is a relatively infrequent site of metastasis. Furthermore, obstructive jaundice resulting from pancreatic metastasis is extremely rare. This paper examines the case of a 65-year-old woman with small cell lung cancer initially presenting with extrahepatic biliary obstruction. The patient underwent percutaneous transhepatic biliary drainage. The obstruction was relieved with a stent placement, then the woman was treated with combination chemotherapy (irinotecan, cisplatin) and a complete remission achieved in six months.

Primary hepatic lymphoma is a rare disorder representing less than 1% of all extranodal lymphomas. Histological examination of a primary hepatic lymphoma usually reveals a diffuse large B-cell lymphoma; there have been few reports of primary hepatic mucosa-associated lymphoid tissue (MALT) lymphomas. A 67-year-old man was being treated for a duodenal ulcer; while receiving therapy for the ulcer, a liver mass was incidentally found on abdominal ultrasonography. The pathologic diagnosis of the hepatic mass was an extranodal marginal zone B-cell lymphoma of MALT. The patient underwent radiotherapy with a total of 4,140 cGy delivered. The patient achieved complete remission and has been followed for 6 years with no recurrence of the disease. This report reviews the case of a primary hepatic extranodal marginal zone B-cell lymphoma of MALT successfully treated by radiotherapy alone.

Primary pancreatic lymphoma is rare, comprising 0.2~4.9% of all pancreatic malignancies and less than 1% of cases of non-Hodgkin's lymphoma. Many patients are diagnosed with lymphoma after radical resection. We report a rare presentation of diffuse large B cell lymphoma, appearing as a primary tumor of the pancreas. A 61-year old female was admitted to the hospital with the complaint of right upper abdominal pain. Computed tomography of the abdomen showed a well defined mass located at the head of the pancreas. A frozen section of pancreas, during laparotomy, revealed lymphoma. The patient received 6 cycles of chemotherapy and is currently in complete remission. This case underscores the importance of differentiating primary lymphoma from the more common adenocarcinoma of the pancreas as treatment and prognosis differ significantly. Primary pancreatic lymphoma should be considered in the differential diagnosis of pancreatic tumors and an attempt to obtain a tissue diagnosis is always necessary before proceeding to radical surgery, especially on young patients.
