The Prevalence of Human Papilloma Virus in Squamous Cell Carcinoma of Oral Tongue.

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 increase, by acting as an oncogenic agent.

Prevalence of Human Papilloma Virus in Sinonasal Papilloma in Southern Iranian Population.

Statement Of The Problem: Sinonasal papilloma (SNP) is a rare benign lesion characterized by high recurrence rate and malignant transformation.

Purpose: This study aimed to investigate the prevalence of human papilloma virus (HPV) infection in these lesions in South of Iran.

Materials And Method: In this cross sectional retrospective study, a total of 41 patients, 38 SNP and 3 SNP/Squamous cell carcinoma cases, from 2007 to 2014 were studied.

Anaplastic Solitary plasmacytoma of mandible, masquerading as sarcoma.

Plasma cell neoplasm is characterized by a monoclonal neoplastic proliferation of plasma cells and solitary plasmocytoma of bone (SPB) is a localized form. It usually occurs in vertebrae and secondarily in long bones. Its presence in mandible is extremely rare event.

Extramedullary plasmacytoma of the nasal cavity report of three cases with review of the literature.

Extramedullary plasmacytoma is a rare neoplasm characterized by monoclonal proliferation of plasma cells. Most lesions occur in the head and neck, primarily in the upper aerodigestive tract. The nasal cavity and nasal septum are the most common sites of occurrence.

Prevalence of GJB2 (CX26) gene mutations in south Iranian patients with autosomal recessive nonsyndromic sensorineural hearing loss.

Hereditary hearing loss is a genetically heterogeneous disorder. Mutations in connexin 26 (CX26), are a major cause in many countries and are largely dependent on ethnic groups. The purpose of our study was to evaluate the prevalence of GJB2 mutations among affected individuals from south of Iran.

Salivary gland tumors in maxillofacial region: a retrospective study of 130 cases in a southern Iranian population.

Tumors of the salivary glands are uncommon head and neck neoplasia. We conducted a retrospective study of 392 cases over the last 6 years in Shiraz, south of Iran, to investigate the clinicopathological features of these tumors in Iranian population. The age of the patients ranged from 8 to 85 years, with the mean age 44.

Study the polymorphism of CYP3A5 and CYP3A4 loci in Iranian population with laryngeal squamous cell carcinoma.

Cancer reflects a complicated network of interactions between genes and environmental factors. Cytochrome P450 (CYP) is a multi-gene superfamily participating in the metabolism of xenobiotics. The aim of our study was to examine whether polymorphisms in the CYP enzyme genes affect the risk of developing larynx squamous cell carcinoma (SCC).

Expression of Ki67 and P53 in primary squamous cell carcinoma of the larynx.

Unlabelled: We studied a series of untreated laryngeal carcinomas in an attempt to determine the relationship between Ki67 and p53 expression and clinicopathological findings. The relationship between expression of these markers in non-tumoral tissue was also evaluated in order to investigate the possible role of immunohistochemistry as a diagnostic aid in evaluating laryngeal biopsies.

Materials And Methods: Samples from 54 patients with laryngeal squamous cell carcinoma (SCC) were analyzed retrospectively.

Fine needle aspiration findings in angiofollicular hyperplasia with eosinophilia: a case report.

Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon vascular inflammatory lesion usually involving the dermis or subcutaneous tissue of the head-neck region of middle-aged women. Histologically, this lesion shows a florid proliferation of vessels lined by particular endothelial cells and an inflammatory infiltrate composed of lymphocytes and eosinophils.

Case: A 30-year-old woman presented with multiple periauricular skin nodules.

Histological analysis of the effect of accelerated portland cement as a bone graft substitute on experimentally-created three-walled intrabony defects in dogs.

Background And Aims: Recent literature shows that accelerated Portland cement (APC) is a non-toxic material that may have potential to promote bone healing. The objective of this study was to histologically evaluate periodontal healing focusing on new bone regeneration following implantation of APC into intra-bony defects in dogs.

Materials And Methods: Three-wall intra-bony periodontal defects were surgically created at the mesial aspect of the first molar in both sides of mandible in six dogs.

Diagnosis of pleomorphic adenoma in a heterotopic salivary gland: a case report.

Background: The histologic diversity encountered in pleomorphic adenoma may cause diagnostic difficulty in fine needle aspiration cytology (FNA) due to limited and selective sampling.

Case: A 40-year-old woman presented with a mass in the anterior aspect of the neck along the sternocleidomastoid muscle. FNA revealed a cellular tumor with a chondrimyxoid background and epithelial cells intermingled with a few mesenchymal cells.
