Objective. Many different neoplastic and non-neoplastic lesions involve the skeletal system. Clinical and radiological tools primarily assess the nature of these lesions. The aim of this study was to analyze the cystic bone lesions in a pathologic point of view. Methods. All bone cysts between 2002 and 2013 retrospectively evaluated under the guidance of clinical information and radiological im...

We present 2 patients with giant cell reparative granuloma (GCRG) of the sphenoid bone. The first patient is an 8-year-old boy with involvement of the greater wing, and the second is a 53- year-old man with a lateral pterygoid plate mass. Both patients presented with rapid expansion of lytic bone lesions, which had solid and cystic components and lacked matrix calcification. Biopsies were indet...

Cystic jaw bone lesions have been largely studied and discussed since the beginning of their recognition. Although many them already well-defined, some go on generating divergent opinions, such as lateral periodontal cyst (LP C) botryoid odontogenic (BOC). The objective this article is to report two cases unusual characteristics, one about a other cyst, presenting considerations clinical, radio...

Hydatid disease is an extremely uncommon differential diagnosis in the cystic/lytic lesions of bone. We present a rare case of echinococcal infection of femur which presented as pathological fracture in a middle-aged female and diagnosis was confirmed by histopathology. Hydatid disease of bone is often asymptomatic, and its diagnosis is usually made when lesions have become extensive.

Cystic angiomatosis is a rare, benign, multifocal disorder of bone and viscera. Angiomatous deposits result in bone lysis and organ dysfunction. Bony cystic lesions occur in the axial and proximal appendicular skeleton. Lesions may cause bone pain or pathological fracture. Diagnosis is difficult, of exclusion and demands a biopsy. The prognosis varies upon whether the lesions are solely skeleta...

OBJECTIVES The purpose of this retrospective study is to find the differentiating characteristics of cystic and cystic-appearing lesions that involve the impacted mandibular third molar by analyzing panoramic radiographs and computed tomography images, and to aid the preoperative diagnosis. MATERIALS AND METHODS Eighty-one patients who had a mandibular cystic or cystic-appearing lesion that i...

Background: Few studies regarding oral lesions of children and adolescents were reported in the medical literature. The aim of this study was to determine the frequency of these lesions in patients from birth to 20 years old in Babol, Northern Iran.Methods: The slides of all cases of oral lesions in children and adolescents, between 1990 and 2012 were obtained from the pathology archives of Sha...

Gorham-Stout (GS) disease is a rare bone disorder of unknown etiology that is characterized by local proliferation of small vascular or lymphatic channels, resulting in progressive osteolysis and bone resorption. The diagnosis of GS disease is one of exclusion, with radiography and histopathology playing key roles. We describe a 9-year-old girl who presented to us with dyspnea and bone pain. Sh...
