A 12-year-old castrated male miniature pinscher dog presented with right forelimb lameness. An expansile osteolytic lesion of the right humerus was conspicuous on right forelimb radiographs. Thoracic and abdominal radiographs showed multiple lytic bone lesions on the right scapula, ribs, vertebrae, femurs and pelvis. Additionally, an expansile osteolytic lesion was observed in two thoracic vertebrae and two ribs. Many plasma cells were identified on fine-needle aspiration of the right humerus expansile osteolytic lesion, and monoclonal gammopathy consistent with multiple myeloma was confirmed

Abstract:
Brown tumor is a non-neoplastic bone lesion that develops secondary to hyperparathyroidism and it is very rare in the maxillofacial region. We report the case of a 59-year-old man who presented with pain and a swelling in the left cheek. Computed tomography (CT) demonstrated an expansile and radioluscent lesion in the left maxillary sinus. Incisional biopsy was performed, and the diagnosis was Brown tumor. Brown tumor must be considered in the differential diagnosis of expansile lesions of maxillary sinus.

Abstract:
An aneurysmal bone cyst (ABC) is a benign, expansile, non-neoplastic lesion of the bone, characterized by channels of blood and spaces that are separated by fibrous septae. Giant ABC is an uncommon condition and can be difficult to handle because of the destructive effect of the cyst on the bones and the compressive effect on the nearby structures, especially in weight-bearing bones of the body commonly affecting the younger age group. Here, we present a case of a bone lesion in the left proximal femur of a six-year-old child, who had a previous history of right-sided Nephrectomy due to Wilms’

Abstract:
Solitary periungual angiofibromas can often be challenging in the diagnosis and treatment of such common lesions. Because of the various histologic presentations of fibrous skin tumor, a complete differential diagnosis would include hemangioma, seborrheic keratosis, fibroma, and digital fibrokeratoma. Treatment by total sharp excision can often be accomplished, depending on the morphological appearance of the lesion. An incisional biopsy of a more expansile lesion may be warranted.

Here we present an unusual case of an intraosseous dermoid that presented initially as a lytic lesion, off of the midline and not associated with cranial sutures or fontanelles. The diameter of the lesion grew to approx 15 mm over time, thus the decision was made to take the child to surgery for removal of dermoid with the use of neuronavigation and cranioplasty. A dermoid cyst was confirmed on histopathologic analysis.

Complete excision of these lesions at the craniovertebral junction is associated with high surgical morbidity.

Abstract:
Aneurysmal bone cysts (ABCs) are benign, non-neoplastic, expansile, vascular, locally destructive lesions. The lesion may arise de novo (65%) or secondarily (35%) in pre-existing benign or malignant lesions (giant cell tumor, osteoblastoma, chondroblastoma, angioma, and others). The calcaneus is a rare localization for ABC, comprising only 1.6% of the cases. In this paper, we present a case of a female patient with a 3-month history of heel pain that got worse and was accompanied by swelling and difficulty in walking. The magnetic resonance images of the postero-lateral calcaneus showed a cont

Abstract:
Aneurysmal bone cyst (ABC) is benign lesion of long bone metaphysis, but it can also become locally aggressive lesion. ABC affects mostly medullary region of long bone metaphysis that predominantly affects children and young adults. Meta-diaphysis of the long bones and posterior elements of the vertebrae are the most common sites of involvement. ABCs can involve every skeletal site, but the most common locations are the metaphysis of the long bones, followed by the spine. However, diaphyseal lesions may occur. Patients with ABCs typically present with insidious onset of pain, swelling or a pal

Background: Fibro-osseous lesions include a variety of bone lesions with different clinical and histopathological features. Case Description: We report a case of cemento-ossifying lesion involving the left ethmoid and sphenoid sinus in a 17-year-old male patient. Computed tomography showed an expansile hyperdense lesion with sclerosed peripheral mantle epicentered on the left ethmoid and sphenoid sinus and extending into the left nasal cavity. Magnetic resonance imaging was done for preoperative planning. Transnasal endoscopic resection was performed and histopathological examination confirmed

A 23-year-old female patient presented with diffuse swelling causing intermittent pain involving the left side of the face that had been present for over 10 years. Extra-oral examination revealed expansile lesions in the maxilla and mandible, that appeared mixed radiolucent-radiopaque on panoramic radiography. The maxillary lesion resulted in opacification of the maxillary sinus. The left side of the mandible presented with trabecular bony changes and larger radiolucent areas (Figure 1). Cone-beam computed tomography (CBCT) imaging revealed ground-glass opacification and significant expansion

ABSTRACTIntraosseous hemangioma is a rare bone tumor accounting for 0.7%–1.0% of all bone tumors. In the skull, frontal bone is the commonly involved bone. An 8-year-old female presented to our outpatient department with complaints of pain and swelling over forehead for 4 months. X-ray revealed a lytic expansile lesion involving frontal bone with sunburst pattern of bony spicules radiating to periphery of the lesion. Magnetic resonance imaging revealed the presence of a well-circumscribed lesion with both intra as well as extracranial components. Histopathology revealed a vascular tumor consis

The lesion presented as a bleeding papillary mass in the 85/46 region that extended to the floor of the mouth, causing displacement of the tongue (Figure 1A-B). Upon cone-beam computed tomography (CBCT) examination, an expansile homogenous intermediate density lesion was noted with complete destruction of the bucco-lingual cortical bone.

Abstract:
Juvenile ossifying fibroma (JOF) is an expansile intra-osseous lesion of the jaw that emulate odontogenic lesions frequently seen in patients under 15 years of age. They are histologically characterized by the presence of fibrous stromal cells along with mineralized tissues. Clinically, these are characterized by early age of onset, histological patterns, high rate of recurrence and the aggressive local behavior. The differential diagnosis of JOF with other fibro-osseous lesions of the jaw should be made along with an essential microscopic examination and be largely based on the character of t

Abstract:
Key findings that aid in the diagnosis of an aneurysmal bone cyst are: 1) typically the patients are young individuals less than 20 years old; 2) an expansile bone lesion is bordered by a thin, low signal intensity rim mass; 3) the lesion is inhomogenously increased in signal on T2-weighted images; and 4) multiple fluid-fluid levels are seen with the mass on T2-weighted magnetic resonance imaging scans.
