Background and study aims: We previously reported our discovery of a white opaque substance (WOS) that is opaque to endoscopic light inside the epithelium while using magnifying endoscopy (ME) to examine gastric epithelial neoplasia. Histopathologic analysis revealed that the WOS comprises minute lipid droplets (LDs) accumulated within the neoplastic epithelium. In addition, the WOS was found i...
Gichuhi S, Macharia E, Kabiru J, et al. Topical fluorouracil after surgery for ocular surface squamous neoplasia in Kenya: a randomised, doubleblind, placebo-controlled trial. Lancet Glob Health 2016; 4: e378–85— In this Article, the definition of CIN in table 1 should have read “CIN=conjunctival intra-epithelial neoplasia”. This correction has been made to the online version as of April 7, 2017.
background and aims: ovarian cancer is one of most common causes of cancer related women's mortalities. human papilloma virus is a known factor concerning cervical cancer but its role in causing ovarian cancer is not yet verified. a few studies also identified hpv dna in ovarian carcinoma tissues. however, some studies did not detect hpv dna in ovarian carcinoma tissues. in this article, we inv...
It is recognised that a significant number of patients who develop vulvar intra-epithelial neoplasia (VIN), will have had previous genital tract neoplasia. This has resulted in speculation that there may be a common aetiology and, in particular, on the possibility of an infective element. Four such cases from the Vulva Clinic at the Western Infirmary, Glasgow are presented for discussion.
DNA from human papillomavirus (HPV) type 16 has been recently identified in conjunctival epithelial dysplasia and carcinoma. In other body sites, HPV 16 is thought to play a role in the development of dysplastic lesions. To further explore the relationship between HPV and conjunctival neoplasia, we examined paraffin-embedded tissue samples from 42 biopsies or excisions from 38 patients whose le...
Matrix metalloproteinase 9 is a zinc-dependent extracellular matrix remodeling endopeptidase directly involved in the local invasion mechanisms and in metastasis. The current review aims to evaluate the expression of MMP-9 and its prognostic value in the most common epithelial and lymphatic neoplasia of the pelvic-abdominal region. We included 19 studies published between January 1st, 1995 and ...
Colorectal epithelial neoplasia (CR-EN), both adenoma and adenocarcinoma, may develop from the essential tubules of the colorectum. In order to conclude the carcinogenesis of the colorectal cancer more clearly, the biological features including the genetic abnormality of the nonneoplastic mucosal epithelium of colon and rectum, which coexist in connection with CR-EN, should be investigated. In ...
Changes in tissue homeostasis, acquisition of invasive cell characteristics, and tumor formation can often be linked to the loss of epithelial cell polarity. In carcinogenesis, the grade of neoplasia correlates with impaired cell polarity. In Drosophila, lethal giant larvae (lgl), discs large (dlg), and scribble, which are components of the epithelial apico-basal cell polarity machinery, act as...
