Background Cervical cytology has continually evolved. Nowadays, the category of atypical glandular cells (AGC) is less frequent than atypical squamous cells (ASC), associating poorlyreproducible inter-observer interpretation. Cellular characters sometimes surpass benign reparatory processes or associate high-grade squamous precursor lesions, glandular neoplasia, including cervical adenocarcinom...
Neoplastic transformation of human epithelial cells in vitro after exposure to chemical carcinogens.
Human foreskin epithelial cells were transformed to an anchorage-independent state of growth (in soft agar) and neoplasia (invasion of chick embryonic skin in vitro). Aflatoxin B1, N-methyl-N'-nitro-N-nitrosoguanidine, propanesultone, beta-propiolactone, or ultraviolet absorbance at 254 nm were used successfully as carcinogens. These foreskin epithelial cells, like human foreskin fibroblasts, w...
background: oral cancer is among the 10 most common cancers worldwide with an increasing global incidence. compromised antioxidant defense system plays a role in occurrence of cancer. this study evaluated the salivary antioxidant level of oral cancer patients compared to a control group. patients and methods: this case-control study was conducted on 22 oral squamous cell carcinoma patients pres...
primary de novo intraosseous carcinoma is a rare neoplastic lesion which commonly occurs in the jaws. it is an epithelial odontogenic malignancy arising from odontogenic epithelial residues in the bone rather than from a preexisting epithelial lesion. in the present case report, the clinical, radiological and histological features of primary de novo intraosseous carcinoma are discussed and its ...
conclusions according to the low prevalence of hcmv in oscc, it seems that this virus plays a minor role in this kind of cancer at least in southeast of iran. more comprehensive studies are needed to investigate the oncomodulatory effect of this virus on oscc. results the mean age of the patients (66.7% female and 33.3% male) was 58.6 years. only three cases (6.3%) of the grade i, oscc biopsies...
background:non-melanoma skin cancer (nmsc), the most prevalent types being squamous cell carcinoma (scc) and basal cell carcinoma (bcc), is the most common type of malignancy in human beings. these neoplasms are more frequent in the elderly and fair skinned people and mainly occur on sun-exposed sites of the body. ultraviolet b (uvb) has a well-known effect in induction and promotion of growth ...
abstract background and aim: oral cancer is one of the most common cancers of the head and neck. considering the high prevalence and mortality percentage of oral cancer and the significant advances in immunology and identification of different cytokines, the aim of the present study was to compare the concentration of il8 in saliva of patients with oral squamous cell carcinoma (oscc) and health...
squamous cell carcinoma, a cancer of keratinocytes origin, mostly involves sun-exposed areas of the skin. to study the pathologic and demographic features of this disease, records of 395 patients of squamous cell carcinoma of skin and lip were reviewed. most of the patients (83%) aged 40 years or more at the time of diagnosis. respectively, 74.4% and 75.8% of cases with skin and lower lip carci...
Pseudoepitheliomatous hyperplasia (PEH) is a histopathological reaction pattern to various stimuli, which includes trauma, infection, inflammation, neoplasia. It is seen as tongue like epithelial proliferation invading the connective tissue and should not be mistaken for squamous cell carcinoma (SCC). This review enlists oral lesions which exhibit PEH with a note on how to differentiate SCC fro...
