Penile cancer shows variable incidence in different countries with a higher prevalence in developing countries. Squamous cell carcinoma represents the most common histologic type. The seventh decade of life corresponds to the mean age at diagnosis, but it is not an unusual diagnosis among young adults. Most cases present as "in situ" neoplasia or loco regional disease; however, systemic dissemi...

This study aims to determine the gene expression for c-abl and YWHAZ in gastric cancer and the differences between the c-abl and YWHAZ gene expression inside the tumor versus healthy tissue (at the resection edges). This prospective study included 34 patients with gastric neoplasia, 21 men and 13 women, aged between 49 and 79 years (65.5 years median). After the surgical procedure, in these cas...

BACKGROUND Annexins are calcium and phospholipid binding proteins that form an evolutionary conserved multigene family. Considerable evidence indicates that annexin A10 (ANXA10) is involved in tumoral progression, although little is known about its role in human oral carcinogenesis. In this study, we investigated the involvement of ANXA10 in oral squamous cell carcinoma (OSCC). METHODOLOGY/PR...

Background and objective Oral tongue Squamous Cell carcinoma (SCC) commonly involves males between the sixth to eighth decades of life. Major risk factors are tobacco usage and alcohol consumption. The increasing number of patients developing oral tongue cancer without these well-known risk factors suggests that a viral infection, such as Human Papillomavirus (HPV), may be responsible for this ...

Pericytes are important cellular components of the tumor microenviroment with established roles in angiogenesis and metastasis. These two cancer hallmarks are modulated by enzymes of the LOX family, but thus far, information about LOX relevance in tumor-associated pericytes is lacking. Here, we performed a comparative characterization of normal and tumoral pericytes and report for the first tim...

BACKGROUND The object of this study was to examine whether a new protocol including step-sectioning and immunohistochemistry (IHC) staining of axillary sentinel nodes (SN) would lead to detection of more metastases in patients with breast cancer. MATERIALS AND METHODS Sixty-nine tumor free sentinel lymph nodes were examined. Step frozen sectioning was performed on formalin fixed SN and staine...

Langerhans cell histiocytosis (LCH) is a malign proliferation of dendritic cells which are able to infiltrate any organ and system. LCH could be restricted to a single organ. In adults, LCH is usually restricted to the lungs. Skin involvement of LCH in adults is rare. However, in pediatric group, skin is a one of the predominant organ which LCH involves solely or as a part of systemic disease. ...
