Fibrous dysplasia (FD) is a developmental anomaly in which the normal bone marrow replaced by fibro-osseous tissue. can affect either single (monostotic) or multiple (polyostotic) bones. Craniofacial FD monostotic involving craniofacial However, CFD one of rare forms FD. Aneurysmal cyst (ABC) non-neoplastic lesion. ABCs are expansile lytic lesions composed numerous blood-filled channels and cys...

Pathological structures called epidermoid bone inclusion cysts are surrounded by a layer of stratified squamous epithelium that contains keratin debris. They go the name epidermal as well. Intraosseous uncommon lesions can develop result trauma (puncture wound or pressure erosion). typically affect toes, phalanges, and head. The distal phalanx fingers is where phalangeal involvement most freque...

Intraosseous lipoma is a rare, benign primary tumor occurring in the bone. Herein, we reported a 45-year-old manwith chronic right posterior heel pain. In this study, the man was treated conservatively due to plantar fasciitis. Duringa one-month follow-up visit, the patient had no symptoms of relief in the right heel pain. Initially, calcaneal X-raywas taken, which revealed an...

INTRODUCTION Ollier's disease is a rare nonhereditary disorder characterized by multiple enchondromas with a predilection for unilateral distribution. Malignant changes in Ollier's disease may occur in adult patients. Radionuclide bone scanning is one method used to assess lesions depicted on radiographs or magnetic resonance images that are presumed to be enchondromas. Also, a bone scan may gi...

aneurysmal bone cyst (abc) is blood filled expansile cystic lesion that most commonly occurs in patients during the second decade of their lives. traditionally it has been described as a benign lesion but can be locally aggressive and result in the destruction of the involved bone. treatment methods include surgical excision and curettage with or without bone grafting. we report a proximal femu...

Abstract Introduction/Objective Aneurysmal bone cyst (ABC) is a rare, benign lesion that was first described by Jaffe and Lichtenstein in 1942. Primary ABC usually affects vertebrae metaphyseal regions of long bones, particularly femur tibia. Only 2-3% ABCs occur the head neck region, with mandible maxilla being most common. It arises mostly children young adults, mean age 20 yo, no gender pred...

An infected epidermoid cyst presented on CT as a primarily dense, sclerotic expansile lesion in the greater wing of the sphenoid bone. Presumably, infection was responsible for the atypical appearance.

Gorlin-Goltz syndrome is an autosomal dominant and a rare hereditary disease. Diagnosis of this syndrome is based on major and minor criteria. We report a Gorlin-Goltz syndrome in a 25-year-old male who was presented with progressive pain of maxilla and mandible over 5 years. The pain was diffuse and compatible with expansile cyst in alveolar ridges on panoramic radiography. In physical examina...

The differential diagnosis for expansile masses of the sphenoid sinuses includes both benign and malignant lesions. We herein present a case of a 79-year-old female who presented with chronic epistaxis and an expansile soft tissue mass centered in the sphenoid sinus with erosion of the skull base. Endoscopic resection of the lesion was performed, with histopathological examination revealing org...

.m ed kn ow A 49-year-old female was operated for left lateral orbital wall fibrous dysplasia 12 years back. The patient was having a relatively uneventful course till four months back when she started to have headache and noticed a swelling in the scalp which gradually increased in size over a period of time. On examination she had a mild proptosis of the left eye with a normal vision. There w...
