Lymphoblastic lymphoma (LL) of the B cell type is uncommon, and extranodal presentation is even rarer. It is difficult to suspect this diagnosis without clinically obvious lymph nodal mass or bone marrow involvement. A 3-year-old girl presented with progressive pain and swelling of the right knee joint of 3 months duration. Radiograph revealed expansile lytic lesion at the supracondylar area of...

Central giant cell granulomas are non-neoplastic lesions of unknown etiology. They affect females more than males with the mandibular anterior region being the most common site of occurrence. Clinically central giant cell granulomas present as asymptomatic, expansile swellings causing deviation of associated teeth. Radiologically they usually presents as multilocular lesions causing expansion o...

Four patients with expansile cystic lesions of the petrous bone had correlative CT and MR scans. Characteristic findings were noted on MR scans obtained with T1- (TR = 400-800, TE = 25-32) and T2- (TR = 2000-3000, TE = 64-80) weighted images. These findings include an expansile cystic lesion centered in the petrous apex with high signal intensity on both the T1- and T2-weighted images, compatib...

mas, are malignant neoplasms arising from a single clone of plasma cells. They are commonly found in the axial skeleton; especially in the spine, pelvis, and skull and are characterized as expansile osteolytic bone lesions on radiography (1). The MR imaging findings of plasmacytoma or multiple myeloma located in the spine has been well described, but nonspecifically (2, 3). Plasmacytomas usuall...

INTRODUCTION Simple bone cyst or unicameral bone cyst (UBC) are benign cystic lesions commonly found in femur and humerus. However hand is a very rare site of occurrence. Treatment described for UBC of hand commonly involves curettage and bone grafting. CASE REPORT A 7 year old right hand dominant girl presented to us with chief complaints of pain and swelling in right 4th metacarpal since 2 ...

Desmoplastic ameloblastoma is an unusual type of ameloblastoma with special histologic and radiographic features and anatomic distribution which differs from those in the classic type of ameloblastoma. The purpose of this article is to assist the dental community in better understanding of this variation of odontogenic tumor. We present a patient with desmoplastic and conventional variant of am...

Cherubism is a rare genetic disorder resulting in the replacement of mandible and sometimes maxilla with expansile cystic lesions. The usually presents childhood, eventual quiescence early adulthood. We report case cherubism involving both complicated by mass effect on nasal cavity left orbit. Pathologic features, clinical considerations, treatment are discussed.&nbsp
