Aneurysmal bone cyst is a benign fibro-osseous lesion usually described in the long bones. Intraorbital aneurysmal bone cyst is a rare clinical entity with an entirely different outcome and prognosis as compared to the usual pediatric orbital tumors. The authors report magnetic resonance imaging (MRI) features of an orbital mass lesion in a 4-year-old child who presented with painless proptosis...

PURPOSE To evaluate factors predictive of recurrence following curettage of simple bone cysts (SBCs) in the proximal humerus. METHODS Records of 29 male and 3 female patients aged 3 to 22 (mean, 11) years who underwent curettage with or without bone grafting for a solitary SBC in the proximal humerus were reviewed. The appearance, size, location, activity level, and fracture pattern of each c...

BACKGROUND Aneurysmal bone cyst was first described by Jaffe and Lichtenstein in 1942. Schajowicz in 1972 in his Histopathological Classification of Primary Bone Tumors (later modified by WHO in 1993) placed it in group IX - tumor-like lesions.

A 4-year-old Shih-Tzu, referred for an enlarged left carpus, was diagnosed with a unicameral bone cyst. A customized titanium device was inserted into cystic lesion and fixed by titanium screws. Sufficient strength of the affected bone with the device inserted to maintain limb function was established after resection of contents of cystic lesion. There was no deterioration of the lesion of bone...

Objectives The aim of the present study was to document the frequency and clinicopathologic features of intra-osseous jaw lesions in an Iranian pediatric population over a 20-year period. Methods Data were obtained from the archives of the Oral Pathology Department, Shahid Beheshti University of Medical Sciences, Tehran, Iran. The lesions were classified into four groups: (A) odontogenic cysts...

A 9-year-old girl with a solid variant of an aneurysmal bone cyst in the 3rd lumbar vertebra showed a good response to low-dose radiation as the only treatment. The solid variant of aneurysmal bone cyst is thought to be a reactive response to intraosseous hemorrhage and is also called giant cell reparative granuloma or giant cell reaction. These lesions in the jaw and the short tubular bones of...

BACKGROUND Mucous retention cyst refers to a cyst made by expansion due to the blockage of the salivary gland near the maxillary sinus, and it is surrounded by epithelial cells. Most of them are small; therefore, they cannot be found well and are frequently with antral polyp. The aim of this study was to evaluate the clinical prognosis of sinus bone graft in patients with mucous retention cyst....

Th e synonym for traumatic bone cyst (TBC) is solitary bone cyst, idiopathic bone cyst and is characterized as the presence of infectious bony cavity fi lled with fl uid and litt le quantities of tissue with no lining of epithelium. Typically these lesions show no symptoms and are detected coincidently while performing routine radiographic investigation for another purpose for which the patient...
