INTRODUCTION Gaucher disease is an autosomal recessive systemic condition, and the most common of the lysosomal storage disorders. It is characterized by lipid accumulation in certain cells and organs, particularly macrophages, which appear on light microscopy as 'Gaucher cells' or vacuolated lipid-laden reticuloendothelial cells. Long bone involvement is common in Gaucher disease, whereas cran...

Received: 18 April 2008 Accepted: 8 October 2008 Abstract: Langerhans cell histiocytosis is a relatively rare unique disease process characterized by an abnormal proliferation of immature dendritic cells usually affecting children and young adults. Jaws are involved in less than 10% of children with the disease while mandibular involvement in young children is uncommon and bilateral affection i...

Although dental disease is common in camelids, primary mandibular osteomyelitis is encountered less frequently than other dental problems. This is fortunate because the condition is characterized by extensive, generalized destruction and lysis of the mandible. Often the condition spans the entire length of the hemimandible, involving the diastema and occasionally the symphyseal region around th...

Fibrous histiocytoma is a benign soft tissue neoplasm that may present as a fi brous mass any-where in the human body. Th e involvement of the oral cavity is extremely rare and very few cases have been reported in the literature until date. We here report a case of benign fi brous histiocytoma localized in the oral cavity in mandibular chin region and the treatment approach that need to be foll...

Segmental resection of the mandible commonly results in deviation of the mandible to the defective side. The amount of deviation depends on the amount of hard and soft tissue involvement, the method of surgical site closure, the degree of impaired tongue function, the number of remaining teeth and the extent of loss of sensory and motor innervations. Prosthodontic treatment along with physical ...

Localized gingival enlargement due to accumulation of amyloid without involvement of other organs is a very rare condition. This article describes a 31-year-old male patient with amyloidosis involving only the periodont...

Ewing's sarcoma (ES) is an uncommon round cell tumor with an aggressive course affecting mainly children and young adults. Only 1% of cases is reported with jaw involvement and have mandibular predilection. Radiographic finding in ES reflect many destructive nature of the lesion, like osteolysis, cortical erosion, periostitis and soft tissue mass. A case of ES of the mandible is reported with s...
