Immunohistochemical Investigation of the Proliferative Activity of Odontogenic Cysts and Tumors.

Odontogenic cysts and tumors exhibit a broad spectrum of biological characteristics. Despite recent advances in understanding the complex nature of these lesions, relatively less is known about the molecular markers involved in key pathogenic steps, such as proliferation and differentiation. This study aimed to elucidate the expression patterns of p63 and Ki-67 in odontogenic lesions, which may influence the management strategies.

Giant Parotid Pleomorphic Adenoma with Atypical Histological Presentation and Long-Term Recurrence-Free Follow-Up after Surgery: A Case Report and Review of the Literature.

Salivary gland tumors (SGT) comprise 3% of all head and neck tumors, are mostly benign, and arise frequently in the parotid gland. Pleomorphic adenoma (PA) is the commonest SGT, representing 60-70% of all benign parotid tumors. Clinically, parotid PA presents as irregular, lobulated, asymptomatic, slow-growing preauricular mass, involving both superficial and deep lobes, and could grow to gigantic proportions.

Evaluation of concordance between clinical and histopathological diagnoses in periapical lesions of endodontic origin.

Unlabelled: Background/purpose: Periapical lesions of endodontic origin are often diagnosed based on the clinical and radiological presentations that may be different from the histological diagnoses. The purpose of this study was to assess the concordance between the clinical diagnosis of these lesions and the histopathological diagnoses and to analyze their clinical and pathological features.

Materials And Methods: Biopsies of periapical lesions of endodontic origin diagnosed in the histopathology laboratory between 2006 and 2017 were retrieved from the database and used to conduct this retrospective review.

Diagnostic challenges of an unusually large schwannoma of the mandible: Report of a case.

Schwannomas are slow-growing, benign neoplasms arising from the Schwann cells and are commonly reported as peripheral tumors in the head and neck region. Central intramandibular schwannomas are extremely rare lesions. We report a case of intramandibular schwannoma in a 70 year old male patient.

Oral Kaposi Sarcoma in HIV-seronegative Saudi patient: Literature review and case report.

Kaposi Sarcoma (KS) is an intermediate neoplasm affecting the endothelial cells of mucous membranes and skin. It arises most commonly among HIV-infected individuals. We present an intra-oral KS in an 80-year-old Saudi male patient, who is HIV-seronegative, non-immunosuppressed, and with no history of organ transplantation.

Odontogenic tumors: analysis of 188 cases from Saudi Arabia.

Background And Objectives: Odontogenic tumors (OTs) represent an uncommon group of lesions that arise from the tooth-forming apparatus. They pose a significant diagnostic and management challenge. There is a lack of data among the Saudi population.

Epithelioid Osteosarcoma of the Maxilla: A Case Report and Review of the Literature.

Epithelioid osteosarcoma is an uncommon variant; only 4 cases have been reported in the jaw area, 2 of which were in the maxilla. A 22-year-old woman, in the eighth month of pregnancy, presented to the oral surgery clinic with a mass in the right maxilla that had rapidly expanded over the past 3 months. Computed tomography scans showed an ill-defined sclerotic destructive lesion that formed bone matrix in its soft tissue extension.
