we report occurrence of a rare case of giant cell tumor (gct), in a 28-year old woman, arising from anterior arc of right 6 th rib during pregnancy. it progressed rapidly during breast-feeding period, mimicking malignant bone tumor at delayed presentation.

A benign pleomorphic adenoma is the most common tumor of the salivary glands. This tumor has the potential to metastasize to bone, the head and neck region, visceral organs and skin. Although there a few reports about a benign pleomorphic adenoma metastasizing to the maxillary sinus in the paranasal sinuses, there are no reports about a metastatic benign pleomorphic adenoma in the sphenoid sinu...

UNLABELLED Osteochondroma, which is also known as exostosis, is the most common benign bone tumor. Although foot and hand surgeons frequently encounter the subungual exostosis, exostoses commonly localize to other areas of the skeleton as well. In this review, we describe the clinical and diagnostic imaging characteristics of benign bone tumors and, in particular, the osteochondroma and its sur...

Giant-cell tumor of the bone is a benign tumor, but with high local aggressiveness, even with risk of distant metastasis. From an epidemiological standpoint, giant-cell tumor of the bone accounts for 4-5% of primary bone tumors and ~20% of benign bone tumors; commonly affects adults between 20-40 years, slightly more common in females. We present the case of a 57-year-old woman, without signifi...

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...

Fibrous dysplasia is a benign disorder in which the normal structure of the bone and marrow is replaced by fibrous tissue1,2. It was first described by Lichtenstein in 19383 and it represents 5 to 7% of all benign bone tumors4,5. This lesion type can involve a single bone or multiple bones, in one-fourth of the cases being localized at the head and neck level2. In patients with skull involvemen...

   Aneurysmal bone cyst (ABC) is a benign expansile bone tumor, most commonly involving the medulla of long bones. ABC rarely arises within the cortex or in the subperiosteal region, radiographically mimicking other conditions, in particular surface osteosarcomathat is low-grade in nature and may go secondary ABC changes, and telangiectatic osteosarcoma. Both of these are sometimes mistaken mic...

Osteoid osteoma is a benign primary bone tumor containing a small region of abnormal osteoid with osteoblasts and variable surrounding reactive bone. Osteoid osteoma accounts for approximately 11% of all benign tumors.1 The majority of osteoid osteomas are monofocal with a single nidus. The orthopedic and radiology literature is scattered with several case reports of multicentric osteoid osteom...
