Aneurysmal bone cyst (ABC) is a rare benign cystic lesion of the bone that composes 1-2% of the entire bone tumors. Some are idiopathic, and some occur secondary to other tumors such as giant cell tumor and chondroblastoma. In this article, we report the clinical, radiographic, and histological findings of a secondary ABC following chondroblastoma of the patella with a review of the literature.

Simple bone cysts are common, benign, fluid-filled, cystic lesions that occur mostly in the metaphysis of the long bones and are rarely found in vertebrae. A case of a simple bone cyst in the spinous process of the fourth cervical vertebra in a 26-year-old woman is reported. According to the radiologic findings, the lesion was identified as a simple bone cyst, and the diagnosis was verified by ...

Ossifying Fibroma is a benign fibro-osseous tumor, but osteolytic and invasive, as well being rare lesion. It manifests itself more frequently in the mandible than upper jaw, located preferably molar (52%) or premolar (25%) region. most commonly diagnosed women (5:1) between 3rd 4th decades of life. related to other pathologies such bone dysplasia, florid cement-osseous among others. This lesio...

INTRODUCTION Osteoid osteoma is a benign tumor of the growing skeleton. It presents with pain, which is usually worse at night. The radiographic features consist of a central oval or round nidus surrounded first by a radiolucent area followed by another area of sclerotic bone. In the hand, osteoid osteoma is more commonly located in the phalanges and carpal bones. The metacarpals are the least ...

Primary tumors of the calvarium are infrequent, and with the exception of osteoma, lesions confined to the surface of the skull are very rare. The differential diagnosis includes benign and malignant matrix forming tumors, other mesenchymal tumors, and reactive lesions. Fibro-osseous lesions are characteristically centered within bone and surface fibro-osseous lesions always prompt consideratio...

Background- Central giant cell granuloma is an uncommon benign tumor of jaws, most prevelant in anterior region mandible. It has both aggressive and non nature occurs young adults.
 Case presentation - We present a case central 21 year old boy who presented with all the features solitary bone cyst. Lesion was right body mandible diagnosis made histopathologically followed by surgical enucl...

The central odontogenic fibroma (COF) is a rare benign mesenchymal tumour of jaw bone derived from the ectomesenchyme. It characterized by fibrous mature stroma with variable number strands or islands inactive-looking epithelium. presented case 46 years old male complaining asymptomatic mandibular bony swelling. Radiographically, lesion unilocular radiolucent, root resorption and displacement t...

Mandibular bone depression, also known as Stafne bone cavity, is defined as a bone depression filled mainly with salivary gland tissue. Parotid gland bone defects are infrequently observed. We report the case of a 52-year-old male patient who underwent radiographic examinations due to temporomandibular joint dysfunction, and a radiolucent area was detected in the mandibular ramus, with a provis...

Fibrous dysplasia is a benign fibro-osseous lesion progressing with one or more bone involvements in the skeleton. Even though it is a benign tumor, it may potentially transform into a malignant one. While the most frequently involved zones in the head-neck zone include the maxilla, mandible, parietal, occipital, and temporal zones, the involvement of the ethmoid bone is rather rare. This artic...

BACKGROUND: Bone tumours involving hands are usually benign but can be locally aggressive. Several treatments have been described. Usual modalities of treatment include curettage and bone grafting. In more advanced stages when short bones the hand involved with than 70% cortical destruction, or such option is not possible (as non-contained breaches, pathological fracture), only resection amputa...
