It uncommon intermediate grade epithelial the cavity, with tendency recur associated malignancy, Schneiderian membrane Reporting case inverted right well differentiated squamous cell carcinoma, invad...

The squamous odontogenic tumour is a rare benign neoplasm whose aetiology remains unknown. It usually appears in the jaw and its origin could be related to the ephitelial remnants of Malassez. Histologically comprises numerous islets of squamous, non-keratinized, well-differentiated and rounded epithelial cells a fibrous stroma without signs of atypical cells. There is a non-neoplastic lesion w...

AIM To determine the size of a cervical biopsy specimen with human papillomavirus (HPV) infection required to enable in situ hybridisation to be carried out with a guarantee of a reliable result. METHODS In situ hybridisation was carried out in 142 cervical uterine biopsy specimens classified histologically as low grade and high grade squamous intraepithelial lesions. Epithelial length at the...

PURPOSE To study the peculiarities of vascularization at the stromal-epithelial interface in different types of epithelia and their alterations in precancerous lesions. MATERIALS AND METHODS Peritumoral tissues of 310 patients, tissues of 180 healthy persons and of 50 human embryos and fetuses were used. Traditional histological as well as immunohistochemical methods have been used. RESULTS...

Squamous cell carcinoma (SCC) is a tumor consisting of squamous epithelial cells. This tumor is relatively uncommon in goats. In this report, we discuss clinical, gross and histopathological features of SCC in six goats. The goats were referred to the veterinary clinic with a progressive ulcerative and hemorrhagic mass located in the perineal area. The vital signs (temperature, pulse rate, resp...

UNLABELLED Abnormalities in the p53 gene are regarded as the most consistent genetic abnormalities detected in head and neck squamous cell carcinogenesis. Two new members of the p53 gene family, p73 at the 1p36 region and p63 at the 3q27-29 region, have recently been identified. They share considerable sequence homology with p53 in the transactivation, DNA binding, and oligomerization domains, ...

85 Abstract Objective: We intended to study the cellular proliferation by means of Ki-67 labeling index and the protein product overexpression of p53 in a series of oral intraepithelial lesions and squamous cell carcinoma, to evaluate the potential association between their histologic grades and the expression of the two markers. The expression of these markers on sections taken from hyperplast...

Aim: Evaluation of nuclear anomalies in exfoliated buccal epithelial cells of petrol station attendants and oral squamous cell carcinoma patients. Materials and methods: Study was carried out on 60 subjects. 20 petrol pump attendants, 20-squamous cell carcinoma patients and 20 healthy subjects. They were asked questions regarding their life style and personal factors (age, duration of working i...
