INTRODUCTION First described by Von Recklinghausen in 1891, fibrous dysplasia is a developmental defect of osseous tissue such that bone is produced with an abnormally thin cortex and marrow is replaced with fibrous tissue that demonstrates characteristic ground-glass appearance on x-ray examination. The underlying defect in fibrous dysplasia is a mutation of the GNAS1 gene, which leads to cons...

INTRODUCTION Double-layered patella is a rare intra-articular disorder associated with multiple epiphyseal dysplasia. PRESENTATION OF CASE We present a case of a 40-year old man with acute pain in his left knee after a tackle during soccer play. DISCUSSION Clinical examination and radiographs confirmed the diagnosis of a bilateral double-layered patella with traumatic separation of the osse...

  Background: Children with myelomeningocele (MMC) develop a wide variety of hip deformities such as muscle imbalance, contracture, subluxation, and dislocation. Various methods and indications have been introduced for treatment of muscle imbalances and other hip problems in patients with MMC but there is no study or meta-analysis to compare the results and complications. This review aims to fi...

INTRODUCTION Fibro-osseous lesions constitute a rare benign type of pathology with a non-odontogenic lineage that affect the craniofacial area. According to Waldrom's classification, these lesions are divided into: fibrous dysplasia (FD), cemento-ossifying fibroma (COF) and desmoplastic fibroma (DF). MATERIAL AND METHODS A retrospective study was performed on patients diagnosed with fibro-oss...

Gnathodiaphyseal dysplasia (GDD) is a rare autosomal dominant condition characterized by bone fragility, irregular bone mineral density (BMD) and fibro-osseous lesions in the skull and jaw. Mutations in Anoctamin-5 (ANO5) have been identified in some cases. We aimed to identify the causative mutation in a family with features of GDD but no mutation in ANO5, using whole exome capture and massive...

Florid cemento osseous dysplasia (FCOD) is a rare, benign lesion affecting both the jaws. It is found more commonly in middle aged black females and also in Caucasians and Asians. It is characterized by substitution of bone with cement-osseous tissue. Generally asymptomatic, FCOD is typically an incidental finding in routine radiographs. Radiographic features depend on the developmental stage o...

Objectives: This project explores the demographic and clinical presentation of cementoosseous dysplasia (COD), and their pathognomonic radiographic features. Methods: Demographic and clinical data were collected from the charts of 118 subjects with COD from the Oral Radiology archives. Using a systematic objective survey instrument, 3 general dentists (GP) and 3 oral radiologists (RG) reviewed ...
