Lym-phoid stroma-rich carcinomas arising in other organs have been termed lymphoepithelioma-like carcinoma (LELC). In the liver, primary LELCs are very rare, and the majority has been identified as cholangiocarcino-mas. Here a rare case of lymphoepithelioma-like hepa-tocellular carcinoma (HCC) is described. A 47-year old woman presented with abdominal pain. Ultrasonogra-phy revealed a liver nodule, 2.2 cm in diameter, local-ized in the right lobe, adjacent to the gallbladder. Viral markers for hepatic B virus (HBV), hepatic C virus (HCV) and Epstein-Barr virus (EBV) were negative. The nod-ule was hypoechogenic. The patient underwent sur-gery, with resection of the nodule. Histology showed hepatocellular carcinoma, characterized by a promi-nent lymphoid infiltrate. At immunocytochemistry, tumor cells were reactive for Hep Par1 and glypican 3. Immunophenotyping of tumor infiltrating lymphocytes evidenced the predominance of CD8+ cytotoxic sup-pressor T cells. The postoperative clinical outcome was favorable and the patient was recurrence-free 15 mo after resection. This case, to the best of our knowl-edge, is the first reported non EBV and non cirrhosis-associated lymphoepithelioma-like hepatocellular carci-noma. The association between the lack of EBV infec-tion, the absence of cirrhosis, a "cytotoxic profile" of the inflammatory infiltrate and a good prognosis could identify a variant of lymphoepithelioma-like HCC with a favorable clinical outcome.展开更多

Our analysis shows that while the number of human rabies cases decreased year by year, the number of districts reporting cases did not show significant change. The situations in Guangdong, Guangxi, Guizhou and Hunan provinces clearly improved over the period but they remain provinces with high-incidence, and consequently influence the epidemic situation of surrounding provinces and possibly the whole country. Summer and autumn were high-incidence seasons. Farmers, students and pre-school children represent the high-risk populations, and rates of cases in farmers increased, those for students decreased, and pre-school children remained unchanged. Provinces with active surveillance programs reported a total of 2346 individual cases, of which 88.53% were associated with canines. Postexposure prophylaxis （PEP） of rabies cases was not significantly improved, whereas PEP in post-exposure population was good. In rural regions of China, canine density was reduced somewhat, and the immunization rate increased slightly. Finally we show that while the epidemic decreased 2007 to 2011 in China, cases continued to be diffused in certain regions. Lack of standardization of PEP on rabies eases was the main reason of morbidity. The high density and low immunization of dog in rural areas and the defective situation of PEP are still continuous occurrences in China and remain a cause for concern.展开更多

The pilocarpine test was positive. No tumor or other neurological abnormality was found. She had a 19-year history of autoimmune hepatitis. Flares up were observed following each 3 deliveries. At age of 31 she presented with diarrhea and weight loss. Abdominal tumor was detected by ultrasound. The surgically removed tumor was histologically a benign mesenteric multicystic lymphangioma. Simultaneously, celiac disease was diagnosed. Gluten-free diet resulted in a significant improvement of celiac disease, but not of autoimmune hepatitis. Autonomic neuropathy was proven by standard cardiovascular tests. The patient was a homozygous carrier for HLA DQ2 antigen characteristic for celiac disease and heterozygous for HLA DR3 B8 frequent in autoimmune liver diseases. Our novel observation on association of Holmes-Adie syndrome with autoimmune hepatitis and celiac disease is suggestive for a common immunological background for all three entities present in a patient with mesenteric multicystic lymphangioma.展开更多

Her history showed no indication of hepatitis. Her abdomen appeared to be even and soft, and the liver and spleen could not be felt below the costal margin. Percussion pain in hepatic region was negative. Gastroscopy showed no abnormalities. An abdominal ultrasound examination revealed the presence of hepatic hypoechoic areas and an abdominal CT scan showed multiple roundlike low-density masses in both hepatic lobes. The edges of the focal lesions were smooth and continuous, with a heterogeneous center, the round-like edges were enhanced, but the enhancement in the focal lesions was not obvious.展开更多

We describe the diagnosis and treatment of a 43 year- old woman who presented with a persistent oral ulcer for approximately 1 year, and subsequent pain in the left posterior maxillary region. Clinical examination revealed an ulcer in the left upper molar gingiva, with swelling in the region from the second premolar to the third molar. X-ray images demonstrated the involvement of the maxillary alveolar bone. The histopathological and immunohistochemical features were diagnostic of ACC. ACC is often presented as a gingival lesion; thus, it may easily be neglected by patients. The identification of this tumor using specific pathological analyses prevents misdiagnosis and enables clinicians to determine the appropriate treatment. In this case, no recurrence or distant metastasis was observed after 2 years of follow-up.展开更多

This extremely rare type of tumor occurs most commonly in superficial locations. The case we describe herein is that of a 60- year-old man with two large hepatic masses. The patient＇s tumor was removed radically through an incision due to the inconclusive imaging findings. Follow-up computed tomography showed no recurrence and metastasis after 37 months, suggesting that enucleation was adequate for tumor eradication. To our knowl-edge, this is the first reported case of low-grade myofibroblastic sarcoma in the liver in the English language literature.展开更多

A male patient with abdominal mass presented with symptoms and signs of acute abdomen after admitting for 1 day. After preoperative management and evaluation, an exploratory laparotomy was performed, where rupture of a huge tumor in the stomach was found. A subtotal gastrectomy including the mass was performed and the final immunohistochemical examination verified that the neoplasm was a high risk GIST. The postoperative period was uneventful and the patient received treatment with imatinib mesylate, and regular follow-up without recurrence.展开更多

This paper reports on a 27 year old man with no history of HIV infection or pyothorax who presented with progressive dyspnea and heaviness of chest.Chest radiography revealed complete opacification of the left hemithorax, and contrast enhanced computed tomography showed large left pleural effusion and homogeneous, extensive thickening of the parietal pleura. CT guided biopsy of thickened pleura is suggestive of non-Hodgkin＇s lymphoma-T cell lymphoblastic variety. Physicians should be aware of this rare location of primary pleural lymphoma manifested by thickening of the pleura.展开更多

Case： patient female, with AML-M2, hospitalized with fever, dyspnea, nausea, myasthenia, abdominal pain and diarrhea. In the physical examination exacerbated lesion in abdominal wall and subcutaneous nodules in upper and lower limbs. The computed tomography of the chest evinced area of attenuation in ground-glass opacities in the middle lobe, tending to consolidation and bilateral nodular opacities with ground-glass halo which suggested an infiammatory/infectious process of fungal etiology. Immunoscintigraphy with ^99mTc-besilesomab （Scintimun） identified focal infectious processes in activity, scattered over cutaneous and subcutaneous tissues, predominantly in extremities. In blood culture test, there was a growth ofFusarium sp. There is a difficulty in the diagnosis of fungal infections, both in clinical and imaging methods. There is no specific method to reaching the target. In addition, fungal diseases can be divided into focally localized or disseminated infections. There is a greater difficulty in the diagnosis of immunocompromised individuals due to the deficiency of basic defense mechanisms. Scintimun （scintigraphy with besilesomab） is a useful tool of nuclear medicine in the diagnosis of infectious and inflammatory diseases to allow the image of the whole-body and in vivo detection of early pathological and physiological phenomena, even before anatomical alterations occur.展开更多
