This communication emphasizes that, as...

A 70-year-old man presented to us with the chief complaints of a generalized rash and a mass in the right clavicular region that he first noticed in the year 2012. Biopsy of the mass led to the diagnosis of cutaneous nodular mass-type adult T-cell leukemia/lymphoma (ATLL) in March 2013. Phototherapy was started, and the symptoms improved temporarily. However, in late June 2013, the serum lactate d...

Angiotensin I-converting enzyme (ACE) gene plays an important role in the pathogenesis of cancers. The association between ACE insertion/deletion (I/D) polymorphism and the risk of various cancers has been studied. However, the results of these studies remain conflicting. Therefore, we performed a meta-analysis to evaluate the association between ACE I/D polymorphism and the risk of cancers.

Intravascular lymphoma is a very rare form of large B-cell non-Hodgkin's lymphoma which is characterized by selective growth of lymphoma cells within the lumina of small blood vessels. We report a 64-year-old woman visited hospital because of persistent cough, intermittent high fever as high as 38.7°C and occasional shortness of breath. Her chest CT showed left upper lobe pneumonia and tuberculos...

Carbohydrate antigen 19-9 (CA19-9) is the most frequently applied serum tumor marker for diagnosis of cancers in the digestive organs. However, some patients with benign diseases can have elevated serum levels of CA19-9 as well. The current study presents a 55-year-old female who was admitted to our hospital for further evaluation of a nodular cavity shadow in the right lower lobe and clarificatio...

A 61-year-old woman was diagnosed in June 2011 as having immunoglobulin G (IgG) ĸ-type multiple myeloma (MM), stage II, according to the International Staging System (ISS). Chromosome analysis showed a complex karyotype, including t(11;14) and del 13q. Analysis of the cell surface markers revealed that the cells were positive for mature plasma cell-1 (MPC-1), and negative for cluster of different...

Gliosarcoma (GS) is a rare high-grade malignant tumor with poor prognosis. The survival period of GS ranges from 4 to 18.5 months. Rarely would it be over 40 months. Survival of intraventricular GS is less than 8 months.

Mixed adenoneuroendocrine carcinoma (MANEC) is a rare disease, which mostly occurs in the gastroin testinal tract and pancreas. Here we report a case of gastric MANEC with tri-lineage differentiation in which only the neuroendocrine component had metastasized to the liver. Liver and gastric masses were detected by abdominal computed tomography, and the preoperative relationship between liver and g...

We report the case of a 59-year-old male patient who presented with space-occupying lesions in the pancreas and liver suggestive of metastatic pancreatic cancer.

Squamous cell carcinoma arising from the small intestine is rare and difficult to identify as a primary or metastatic feature. We report a case of small intestinal squamous cell carcinoma manifesting as subacute peritonitis due to perforation. An 80-year-old man was admitted to our hospital with intermittent postprandial abdominal pain. He was diagnosed with acute peritonitis due to gastrointestin...

T-lymphoblastic lymphoma (T-LBP) is a high-grade malignant lymphoma, which possesses the characteristic of high metastasis and high mortality without treatment. We are presenting a special T-lymphoblastic proliferation involving in the oropharynx, nasopharynx, sinus and trachea in a patient with local involved about 15-years without systemic dissemination. The immunophenotype of this case was simi...
