INTRODUCTION Mazabraud's syndrome is a rare but well-described disorder characterized by fibrous dysplasia in single or multiple bones associated with one or more soft-tissue myxomas. In this report, we describe what is, to the best of our knowledge, the first case involving an intra-osseous myxoma. This finding supports, and could provide new insight into, the pathological association between ...
Plasmacytoma is a tumor of monoclonal plasma cells bone or soft tissue that can occur anywhere in the body without evidence systemic multiple myeloma. It may present as solitary masses and classified osseous if arising from extraosseous tissue. Osseous plasmacytoma most common form with predominance active hematopoietic bones, including vertebrae, femur, pelvis, ribs. The diagnosis made biopsy....
BACKGROUND Full-thickness defects measuring 3 mm in diameter have been commonly used in studies of rabbits to evaluate new procedures designed to improve the quality of articular cartilage repair. These defects initially heal spontaneously. However, little information is available on the characteristics of repair of larger defects. The objective of the present study was to define the characteri...
Neuropathy of the mental nerve, also referred to as numb chin syndrome (NCS), is a rare finding that demands for accurate differential diagnosis and therapy. This is a report of two patients with a history of colonic cancer, who experienced a progressive hypaesthesia of one side of the corner of the mouth, lower lip and chin, associated with intermittent phases of pain some weeks prior to admis...
PURPOSE Standard imaging for assessing osseous metastases in advanced prostate cancer remains focused on altered bone metabolism and is inadequate for diagnostic, prognostic, or predictive purposes. We performed a first-in-human phase I/II study of (89)Zr-DFO-huJ591 ((89)Zr-J591) PET/CT immunoscintigraphy to assess performance characteristics for detecting metastases compared with conventional ...
We report a case of an incidental finding of intrathyroid lymph node tissue in a 40-year-old Egyptian female presenting with multinodular goiter. Collections of lymphoid tissue surrounded by capsule and mature fat cells were seen enclosed by normal thyroid follicles. Heteroplasia or deviation of the normal anatomy of the cervical lymph node groups may explain the presence of this lymphoid tissue.
BACKGROUND Hodgkin's disease (HD) most commonly presents with progressive painless enlargement of peripheral lymph nodes, especially around the cervical region. A few children have systemic symptoms and weight loss. At the time of diagnosis, osseous involvement is uncommon CASE PRESENTATION A case is described of Primary Multifocal Osseous Hodgkin's Lymphoma in a seven-year-old boy. He presen...
INTRODUCTION Sacral insufficiency fractures are an important cause of lower back pain in the elderly. Clinically and radiologically, they must be distinguished from osseous metastases, which frequently coexist. To date, no case report has comprehensively explored the full range of diagnostic hurdles and potential pitfalls. CASE PRESENTATION We report the case of a 70-year-old Caucasian female...
A 14-year-old black girl had painless, progressive proptosis and upward displacement of the left eye for approximately six months. Computed tomography showed a massive tumour involving the maxillary sinus with extension into the sphenoid sinus, ethmoid sinus, and orbit. The mass was excised surgically and proved histopathologically to be a juvenile ossifying fibroma. The clinical and histopatho...
Vanishing bone disease, also known as idiopathic osteolysis and Gorham Stout disease is a rare clinicopathological entity characterized by proliferation of intra osseous capillaries and lymphatics thereby leading to bony destruction. All age groups can be affected. The most common sites for predilection are the shoulder and pelvis. The authors report a rare and interesting case of idiopathic os...
