Early esophageal squamous cell neoplasias (ESCNs) are easily missed with conventional white-light endoscopy. This study aimed to assess whether early ESCNs have a spatial predilection and the patterns of recurrence after endoscopic treatment. We analyzed the circumferential and longitudinal location of early ESCNs, as well as their correlations with exposure to carcinogens in a cohort of 162 su...

The objective of this study was to test the hypothesis that HIV interacts with human papilloma virus (HPV) to increase the odds of cervical neoplasia. The study design was a meta-analysis using data pooled from published sources. Studies published between January 1986 and March 1998 were eligible for inclusion if they included data on neoplasia (cytology-based), HIV (defined by laboratory and/o...

The binding characteristics of monoclonal antibodies produced against a variety of human tumor cells were studied on cervical carcinoma cell lines and on exfoliated cells of cervical smears. The latter included normal epithelial cells, cells derived from cervical intraepithelial neoplasia, and cells from squamous cell carcinoma. Monoclonal antibodies that bound in immunoperoxidase assays to eth...

background: tumor markers are substances, which quantitatively changes in serum, during the tumor development, one such tumor marker is serum β2-microglobulin (β2-m). the aim of this study was to establish the role of β2-m as a biochemical parameter for diagnosis and prognosis of oral carcinoma by estimation of serum β2-m levels in potentially malignant lesions, conditions, and oral squamous ce...

Cervical intraepithelial neoplasms The cervical intraepithelial neoplasms (CINs) are abnormalities of the squamous ectocervical epithelium. The first group consists of squamous intraepithelial lesions of low histological stage (LSIL) and includes flat condyloma and CIN I, while the second group consists of squamous intraepithelial lesions of high histological stage (HSIL) including CIN II and C...

squamous cell carcinoma (scc) of the buccal mucosa accounts for 23% to 37% of all intraoral cancers, the prognosis is generally poor. we reported a case of local invasion of buccal squamous cell carcinoma. a 32-year-old man referred to the clinic with a chief complaint of swelling in the right cheek region that initiated from 6 months ago and rapidly grow from one month ago. history of the pati...

patients. in this disease the risk of many malignancies is increased, of which the most important is non- hodgkin lymphoma of the small intestine. other malignancies include adenocarcinoma of the small intestine and squamous cell carcinoma of the esophagus. to the best of our knowledge, thus far only one case of celiac disease associated with hypopharyngeal squamous cell carcinoma has been repo...

background: lung cancer ranks among the most common and most lethal malignancies worldwide. once vascular or lymphatic invasions occur, metastatic dissemination to distant sites is common. bone, liver, adrenals, and brain are the most frequent sites of the distant disease. in this study we present a case of squamous cell carcinoma of lung with metastasis of the left knee bursa.case presentation...
