They are more appropriately termed hamartomas because of their limited growth potential rather than true neoplasm. Clinically, three types of odontomas are identified in the literature: central (intraosseous) odo...

BACKGROUND Mac-2 Binding Protein Glycosylation isomer (M2BPGi) is a novel serological glyco-biomarker for staging liver fibrosis. Here, we aimed to evaluate the efficiency of serum M2BPGi in identifying liver fibrosis stages in Chinese patients with chronic hepatitis C infection. METHODS Serum M2BPGi levels were evaluated in 680 patients with chronic hepatitis C and 164 healthy controls who u...

INTRODUCTION Within the last years one discusses more and more about the association of the cytological examination with the histological one, becoming an important complementary examination. Casebook record. 163 patients were taken in the study, age between 37-79 years old, who showed clinical and radiological signs of broncho-pulmonary cancer. At all the patients a fibro-bronchoscopic examina...

The calcifying cystic odontogenic tumour (CCOT) is a rare benign cystic neoplasm not infrequently associated with odontoma. This report documents a case of CCOT associated with compound odontoma arising in the anterior maxilla in a 25-year-old woman. Conventional radiographs showed a large calcified mass with poorly visualized radiolucent margins. The extent and condition of the internal struct...

Odontomas are the most common type of odontogenic tumors and generally they are asymptomatic. Frequently it may interfere with the eruption of the teeth. This is a case report of a compound composite odontoma in a 9 year old girl, which results in failure of eruption of the permanent upper right central incisor while the contralateral tooth had erupted. A calcified mass was seen in the radiogra...

Odontomas are the most common odontogenic tumours. They are usually asymptomatic and are often discovered during routine radiography. We report a case of a large erupting complex odontoma that caused pain, infection and facial asymmetry. This case is significant as there are few reports of complex odontoma erupting in the oral cavity.

The authors present an interesting and unusual histology of compound odontoma from an 18-year-old female. Part of the subepithelial connective tissue beneath the enamel organ epithelium was replaced by a granular cell nodule, of a probable histiocytic nature. This case represents the first published report of odontoma accompanied by granular cells.

Ameloblastic carcinoma is a rare cause of jaw tumors, especially in children. This rare, rapidly growing, malignant tumor of odontogenic origin affects predominantly the mandible and maxilla. Hypercellularity, lack of differentiation, high mitotic index, vascular and neural invasion are its main histological features. Local destruction and distant metastases to the lungs, bones, liver and brain...

Ameloblastic carcinoma is a rare malignant lesion with characteristic histologic features and behaviour that dictates a more aggressive surgical approach than that of a simple ameloblastoma. However, reliable evidence of its biologic activity is currently unavailable due to the scarcity of well-documented cases. It occurs primarily in the mandible in a wide range of age groups; no sex or race p...

Parathyroid hormone (PTH)-related protein (PTH-rP) is an important autocrine/paracrine attenuator of programmed cell differentiation whose expression is restricted to the epithelial layer in tooth development. The PTH/PTHrP receptor (PPR) mRNA in contrast is detected in the dental papilla, suggesting that PTHrP and the PPR may modulate epithelial-mesenchymal interactions. To explore the possibl...
