A benign tumor of fibrous or fully developed connective tissue.

A benign central bone tumor, usually of the jaws (especially the mandible), composed of fibrous connective tissue within which bone is formed.

A extremely rare bone tumor characterized by abundant collagen formation and a fibrous stroma, without evidence of mitosis or pleomorphism. It appears on x-rays as an osteolytic lesion with well-defined margins and must be differentiated from primary fibrosarcoma of bone. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1441)

A disease of bone marked by thinning of the cortex by fibrous tissue containing bony spicules, producing pain, disability, and gradually increasing deformity. Only one bone may be involved (FIBROUS DYSPLASIA, MONOSTOTIC) or several (FIBROUS DYSPLASIA, POLYOSTOTIC).

Neoplasms produced from tooth-forming tissues.

Tumors or cancer of the MANDIBLE.

Cancers or tumors of the MAXILLA or MANDIBLE unspecified. For neoplasms of the maxilla, MAXILLARY NEOPLASMS is available and of the mandible, MANDIBULAR NEOPLASMS is available.

Cancer or tumors of the MAXILLA or upper jaw.

A family of double-stranded DNA viruses infecting mammals (including humans), birds and insects. There are two subfamilies: CHORDOPOXVIRINAE, poxviruses of vertebrates, and ENTOMOPOXVIRINAE, poxviruses of insects.

'Gingival neoplasms' are abnormal, uncontrolled growths of tissue originating from the gingiva, which can be benign (non-cancerous) or malignant (cancerous), often manifesting as swellings, ulcerations, or masses within the oral cavity.

An odontogenic fibroma in which cells have developed into cementoblasts and which consists largely of cementum.

A benign neoplasm derived from mesodermal cells that form cartilage. It may remain within the substance of a cartilage or bone (true chondroma or enchondroma) or may develop on the surface of a cartilage (ecchondroma or ecchondrosis). (Dorland, 27th ed; Stedman, 25th ed)

A gonadal stromal neoplasm composed only of THECA CELLS, occurring mostly in the postmenopausal OVARY. It is filled with lipid-containing spindle cells and produces ESTROGENS that can lead to ENDOMETRIAL HYPERPLASIA; UTERINE HEMORRHAGE; or other malignancies in postmenopausal women and sexual precocity in girls. When tumors containing theca cells also contain FIBROBLASTS, they are identified as thecoma-fibroma tumors with less active hormone production.

A genus of the family POXVIRIDAE, subfamily CHORDOPOXVIRINAE, consisting of ether-sensitive viruses of leporids and squirrels. They commonly cause tumors and are usually transmitted mechanically by arthropods. MYXOMA VIRUS is the type species.

Viruses that produce tumors.

A usually benign tumor composed of cells which arise from chondroblasts or their precursors and which tend to differentiate into cartilage cells. It occurs primarily in the epiphyses of adolescents. It is relatively rare and represents less than 2% of all primary bone tumors. The peak incidence is in the second decade of life; it is about twice as common in males as in females. (From Dorland, 27th ed; Holland et al., Cancer Medicine, 3d ed, p1846)

Extraoral body-section radiography depicting an entire maxilla, or both maxilla and mandible, on a single film.

A benign tumor composed of bone tissue or a hard tumor of bonelike structure developing on a bone (homoplastic osteoma) or on other structures (heteroplastic osteoma). (From Dorland, 27th ed)

Tumors or cancer of the PALATE, including those of the hard palate, soft palate and UVULA.

A benign tumor derived from striated muscle. It is extremely rare, generally occurring in the tongue, neck muscles, larynx, uvula, nasal cavity, axilla, vulva, and heart. These tumors are treated by simple excision. (Dorland, 27th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1354)

Tumors or cancer of the MAXILLARY SINUS. They represent the majority of paranasal neoplasms.

Tumors in any part of the heart. They include primary cardiac tumors and metastatic tumors to the heart. Their interference with normal cardiac functions can cause a wide variety of symptoms including HEART FAILURE; CARDIAC ARRHYTHMIAS; or EMBOLISM.

The bonelike rigid connective tissue covering the root of a tooth from the cementoenamel junction to the apex and lining the apex of the root canal, also assisting in tooth support by serving as attachment structures for the periodontal ligament. (Jablonski, Dictionary of Dentistry, 1992)

The type species of LEPORIPOXVIRUS causing infectious myxomatosis, a severe generalized disease, in rabbits. Tumors are not always present.

Neoplasms composed of connective tissue, including elastic, mucous, reticular, osseous, and cartilaginous tissue. The concept does not refer to neoplasms located in connective tissue.

Tumors or cancer located in bone tissue or specific BONES.

A fibril-associated collagen found in many tissues bearing high tensile stress, such as TENDONS and LIGAMENTS. It is comprised of a trimer of three identical alpha1(XII) chains.

Femoral neoplasms refer to abnormal growths or tumors, benign or malignant, located in the femur bone or its surrounding soft tissues within the thigh region.

'Gingival diseases' is a general term for conditions affecting the soft tissues surrounding and supporting the teeth, primarily characterized by inflammation, bleeding, redness, or swelling, which can progress to periodontal disease if left untreated.

Neoplasms of the bony part of the skull.

Stable chromium atoms that have the same atomic number as the element chromium, but differ in atomic weight. Cr-50, 53, and 54 are stable chromium isotopes.

The numerous (6-12) small thin-walled spaces or air cells in the ETHMOID BONE located between the eyes. These air cells form an ethmoidal labyrinth.

Tumors or cancer of the PARANASAL SINUSES.

Saccular lesions lined with epithelium and contained within pathologically formed cavities in the jaw; also nonepithelial cysts (pseudocysts) as they apply to the jaw, e.g., traumatic or solitary cyst, static bone cavity, and aneurysmal bone cyst. True jaw cysts are classified as odontogenic or nonodontogenic.

Multiple formation of chondromas. (Dorland, 27th ed)

A mixed tumor of odontogenic origin, in which both the epithelial and mesenchymal cells exhibit complete differentiation, resulting in the formation of tooth structures. (Jablonski, Illustrated Dictionary of Dentistry, 1982)

The bone that forms the frontal aspect of the skull. Its flat part forms the forehead, articulating inferiorly with the NASAL BONE and the CHEEK BONE on each side of the face.

A benign neoplasm of muscular tissue. (Stedman, 25th ed)

Infections produced by oncogenic viruses. The infections caused by DNA viruses are less numerous but more diverse than those caused by the RNA oncogenic viruses.

A non-neoplastic inflammatory lesion, usually of the jaw or gingiva, containing large, multinucleated cells. It includes reparative giant cell granuloma. Peripheral giant cell granuloma refers to the gingiva (giant cell epulis); central refers to the jaw.

A scraping, usually of the interior of a cavity or tract, for removal of new growth or other abnormal tissue, or to obtain material for tissue diagnosis. It is performed with a curet (curette), a spoon-shaped instrument designed for that purpose. (From Stedman, 25th ed & Dorland, 27th ed)

A republic in western Africa, lying between GHANA on its west and BENIN on its east. Its capital is Lome.

A normal developing tooth which has not yet perforated the oral mucosa or one that fails to erupt in the normal sequence or time interval expected for the type of tooth in a given gender, age, or population group.

A benign tumor composed of fat cells (ADIPOCYTES). It can be surrounded by a thin layer of connective tissue (encapsulated), or diffuse without the capsule.
