Relevance of BRAF Subcellular Localization and Its Interaction with and Mutations in Skin Melanoma.

Although skin melanoma (SKM) represents only one-quarter of newly diagnosed skin malignant tumors, it presents a high mortality rate. Hence, new prognostic and therapeutic tools need to be developed. This study focused on investigating the prognostic value of the subcellular expression of BRAF, KRAS, and KIT in SKM in correlation with their gene-encoding interactions.

SOX11, SOX10 and MITF Gene Interaction: A Possible Diagnostic Tool in Malignant Melanoma.

Malignant melanoma (MM) is a highly heterogenic tumor whose histological diagnosis might be difficult. This study aimed to investigate the diagnostic and prognostic utility of the conventional pan-melanoma cocktail members (HMB-45, melan-A and tyrosinase), in conjunction with SOX10 and SOX11 immunohistochemical (IHC) expression. In 105 consecutive cases of MMs and 44 of naevi, the IHC examination was performed using the five-abovementioned markers, along with microphthalmia transcription factor (MITF), S100, and Ki67.

Upper Gastrointestinal Tract Hemorrhage: Unexpected Discovery.

Pica is a serious condition that is characterized by ingesting inedible things which can prove to be fatal (glass, pebbles, etc.) We present the case of a 64-year-old male patient who is admitted to the emergency room with the following complaints: upper GI tract bleeding manifested through hematemesis and melena, epigastric pain, lack of bowel movements. A contrast computed tomograohy is performed showing the presence of a hyper-dense stomach content, gastric wall thickening, abdominal fluid but with no signs of intestinal occlusion.

Multimacronodular pulmonary tuberculosis (bacteriologically negative) confirmed histologically.

Background: Pulmonary tuberculosis can be confirmed by positive bacteriology of sputum, bronchial aspirate or by biopsies (microscopy and/ or culture) or by histopathological examination highlighting specific tuberculous granulomas. When microscopy is repeatedly negative during noninvasive methods, lung biopsy by thoracoscopy is needed for confirmation and differential diagnosis.

Case Presentation: A 40-year-old female patient (nonsmoker, diabetic, with previous exposure to chemicals) was admitted to the hospital for weight loss, dry cough, loss of appetite, pallor, and fatigue.

Significant Shrinkage of Multifocal Liver Metastases and Long-Term Survival in a Patient With Rectal Cancer, After Trans-Arterial Chemoembolization (TACE): A Case Report.

In this paper, we present the successful therapeutic approach of unresectable liver metastases in a patient with rectal cancer.A 63-year-old male underwent endoscopic polypectomy followed by rectosigmoid resection for an adenocarcinoma of the rectum diagnosed in pT2N0 stage. The angio-computed tomography (CT) revealed four metastatic hepatic nodules ranging from 12 to 130 mm in diameter.

Gastrointestinal stromal tumors: review on morphology, diagnosis and management.

Gastrointestinal stromal tumors (GISTs) are the most frequent mesenchymal tumors of the gastrointestinal tract. Major advances in their definition and classification and the understanding of their molecular mechanisms have recently been made. These advances have become a model of targeted therapy in oncology.

[The importance of the I-colic time in colorectal cancer with synchronous hepatic metastases. Specifics of surgical strategy].

Aim: This paper proposes the presentation of a decision-making algorithm in colorectal cancer with synchronous hepatic metastases, as stressing the importance of I-colic time in obtaining the R0 desideratum.

Material And Method: There is no worldwide consensus regarding the surgical attitude in metastatic colorectal cancer. There are some predominantly conservative attitudes which use stenting and neoadjuvant chemotherapy followed by periodical re-evaluation or more aggressive surgical treatment.

[Vascular exclusion of the liver: surgical technique and initial clinical experience].

The intraoperative hemorrhage is the most life threatening complication during a liver resection, reason why the intraoperative vascular control represents one of the key points in the liver resection. This work presents the liver vascular exclusion without caval occlusion technique and also studies the first cases operated in University Surgery Clinic Nr. 1, Targu Mures, Romania.
