Unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC) are benign cystic lesions of bone which are easily diagnosed. However, unusual locations may lead to a false diagnosis. Therefore the aim of this retrospective study was to determine the frequency of unusual localizations. The authors studied 451 cases with histopathologically confirmed diagnosis of UBC or ABC, seen between 1981 and 20...

We treated 13 children with histologically confirmed cystic tuberculosis of bone. Ten had solitary cystic lesions and three had the multicystic form. Signs and symptoms were related mainly to the joint adjacent to the cyst. Most lesions were in the metaphyses of long bones. They were radiolucent, round or oval, and resembled pyogenic infections, aneurysmal and simple bone cysts, cartilaginous t...

background langerhans cell histiocytosis (lch) is a rare disease in which monoclonal migration and proliferation of specific dendritic cells is seen. the disease primarily affects the bones and skin, but there is a possibility that involves other organs or appears as a multi-systemic disease. case report in oral examination of a nine-month girl, two deep wounds with a yellow membrane with appro...

Three middle-aged male patients had painless superior temporal orbital tumor causing globe displacement. Roentgenograms revealed superior temporal orbital tumor with lysis of bone. Surgical excision and curettage completely removed the lesions, which extended from the frontal bone to the periorbita and the dura. Histologically, these were cystic lesions containing a granulomatous reaction to bl...

Open resection of cystic or other benign intramedullary lesions of the fibular head and neck requires dissection and mobilization of the common peroneal nerve. The purpose of this Technical Note is to describe a minimally invasive approach of fibular head bone endoscopy for resection of a bone cyst or other benign intramedullary lesions of the fibular head and neck. The common peroneal nerve, b...

The aim of this study is to present the pathological lesions observed in a skeleton (male, about 35–38 years old) from Radom (Poland), dated 18th–19th century. Bone changes were both femurs and pelvic bones. head femur enlarged deformed, described as “mushroom-shaped”, with areas smooth cortex cavities, or possible cystic residues. neck short thick. bone shaft distal epiphysis do not show any c...

Symptomatic Disease Bone disease in its florid form, osteitis fibrosa cystica generalizata, is now rarely seen. In 1947 Norris (1) found an incidence of this condition of 91% in those with a parathyroid adenoma. The earliest changes can be detected by X-rays of the hands where subperiosteal erosions can be detected in the phalanges (especially radial aspect of the middle phalanges) and terminal...

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...

Nasu-Hakola disease, which is also known as polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (PLOSL), is a rare and mortal human genetic disorder (Verloes et al., (1997) and Bianchin et al., (2004)). Nasu-Hakola is a progressive disease characterized by early onset cognitive dementia and bone cysts (both evident by the third decade). The disease has a worldwide distr...
