AIMS To evaluate whether there is any correlation between the expression of Epstein-Barr virus (EBV) latent membrane protein (LMP) and oncoprotein bcl-2 in the lymph node biopsy specimens of a Chinese patient with EBV-related reactive lymphoproliferation who later developed T cell lymphoma after a short period of time. METHODS Immunohistochemistry, with a standard alkaline phosphatase antialk...

BACKGROUND The survival rate for oral squamous cell carcinoma (OSCC) has remained generally unchanged in the past three decades, underlining the need for more biomarkers to be developed to aid prognostication and effective management. The prognostic potential of E-cadherin expression in OSCCs has been variable in previous studies while galectin-9 expression has been correlated with improved pro...

VIRTUAL SLIDES Hodgkin lymphoma (HL) typically presents as nodal lesion and may involve extranodal sites during the progression of the disease. Primary osseous HL without any lymph node association is extremely rare and only a few such cases have been described in the literature. We present a case of unusual primary HL in rib occurring in a middle-aged female patient. Computed tomography (CT) s...

background: papillary thyroid carcinoma (ptc), occurs mostly in women and sex hormones may play a role in the pathogenesis and clinical course. the objective of this study was to determine the status and prevalence of estrogen and progesterone receptors in ptc with regard to age, gender, tumor size and lymph node involvement. methods: immunohistochemical stains were performed on 92 tissue block...

BACKGROUND The aim of this study was to determine the prevalence of MCPyV in Merkel cell carcinoma (MCC) primaries versus lymph node metastasis and to evaluate possible prognostic factors. METHODS Samples of MCC primaries and lymph node metastases were stained immunohistochemically for the MCPyV large T-antigen and expression was compared to patients´ clinical outcome. RESULTS 41 MCC patien...

A 61-year old woman underwent total abdominal hysterectomy and pelvic lymph node dissection under the diagnosis of endometrial cancer. Although pelvic lymph nodes were positive for adenocarcinoma with psamomma bodies, no other lesion that was a primary lesion was verified. A postoperative study revealed the existence of para-aortic lymph node and supraclavicular lymph node metastases. Therefore...

Background: The bronchopulmonary carcinoid tumor accounts for 1-2% of all adult malignancies of the lung and 20-30% of all carcinoid tumors. Cushing’s syndrome is the result of chronic exposure to increased concentration of exogenous or endo-genus cortisol hormone, and it is generally associated with central obesity, metabolic syndrome, and hypertension. Treatment is based on decreasing cortiso...
