Non Calcifying Type of Calcifying Epithelial Odontogenic Tumor: An Unusual Case Report with Special Emphasis on Histogenesis of Calcifications.

Calcifying epithelial odontogenic tumour also known as Pindborg tumour, is a rare benign odontogenic neoplasm of locally aggressive behavior. It is thought to arise from the epithelial element of the enamel origin which are reminiscent of the cells in the stratum intermedium layer of enamel organ in tooth development. The tumour is characterized histologically by the presence of polygonal epithelial cells, calcifications and eosinophilic deposits resembling amyloid. Non-calcifying epithelial odontogenic tumours are very rare and unusual. Only five cases have been reported in the English literature till date. Here, we present an additional case of non calcifying type along with a review of previously reported cases. It has a much lower recurrence and malignant transformation rate.

Mucocutaneous manifestations of Cowden's syndrome.

Cowden's syndrome is an autosomal dominant genodermatosis with variable orofacial and systemic manifestations. Here we present one such classical case of Cowden's syndrome in a 45-year-old female patient with features such as multiple cutaneous papillomatosis, oral fibromas, and fibromas involving multiple organs such as gastrointestinal tract (multiple polyps), thyroid disorders, and breast cancer.

Extrafollicular Adenomatoid Odontogenic Tumor: An Unusual Case Presentation.

Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin and often misdiagnosed as an odontogenic cyst. It is predominantly found in young female patients, located more often in maxilla, and in most cases associated with an unerupted permanent tooth. There are three variants of AOT namely follicular, extra follicular, and peripheral. We report an unusual case of extrafollicular AOT in maxilla of a 50-year old male patient.

Ambras Syndrome with Gingival Hyperplasia: A Rare Entity.

Ambras syndrome is a rare and special form of congenital hypertrichosis, characterized by dysmorphic facial features and familial pattern of inheritance. It is rarely associated with gingival hyperplasia. We report such a rare entity in a 38-year-old female patient with a history of consanguinity and positive family history.

Efficacy of Diode Laser for the Management of Potentially Malignant Disorders.

INTRODUCTION: Laser dentistry is a one of the upcoming advanced treatment modality for oral mucosal lesions. Diode laser is a soft tissue laser that has found much acceptance in all branches of dentistry. Available compact size and feasibility has render diode laser an enhanced tool for today's clinical practice. The aim of this study is to determine the efficacy and safety of diode laser for the management of white lesions such as oral leukoplakia (OL) and oral lichen planus (OLP). METHODS: The study was conducted by using diode laser 980 nm on 10 patients with white lesions (5 OL and 5 OLP) aged between 35 to 65 years. RESULTS: Of the 10 patients (5 OL and 5 OLP), 3 patients (30%) complained of moderate pain and 7 patients (70%) complained of mild pain, for first 3 days after laser irradiation, and pain disappeared at end of first week. There was no recurrence of the lesion during the 6-month follow up. CONCLUSION: Diode lasers provide acceptable clinical improvement of potentially malignant lesions with minimal side effects. It can be considered one of the best alternative treatment modality for oral mucosal lesions.
