1/32. Osteocartilaginous exostosis of the mandibular condyle. Case report.osteochondroma of the mandibular condyle is extremely rare. An unusual case of a 32-year-old man is reported. Throughout a two-year period the patient suffered from intractable pain in the left T. M. J. region, anterior dislocation of the condylar head, malocclusion and facial asymmetry. Radiologic examination revealed that the cartilaginous cap of an overgrowth had functioned as an articular cartilage. A "pseudo articulation" was created with the prominent articular eminence and allowed an almost free movement of the mandible. review of the seven reported cases revealed that the rare occurrence, natural history, clinical course and lack of recurrence of osteochondroma of the condylar process all substantiate the contention that this overgrowth must be considered as an osteocartilaginous exostosis rather than a neoplasm.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/32. A case of chondromatous tumor of the breast.This report describes an exceedingly rare case of a benign cartilage-containing breast tumor that developed in the right breast of a 52-year-old woman. She found the mass on self examination. physical examination revealed a 1.5 x 1.4 cm, firm, smooth and mobile lump in the lower medial quadrant close to the nipple of the right breast. mammography revealed a slightly indistinct margined, oval-shaped, and high density nodule without microcalcifications. On ultrasonography, the lesion was a hypoechoic, oval-shaped mass with an echogenic spot. The border was slightly rough. Fine needle aspiration cytology revealed some giant cells and necrotic tissue. Excisional biopsy was then performed. Histopathologically, the lesion consisted of islands of mature hyaline cartilage with intervening strands of fibrous stroma. Mammary lobules and ducts were lacking within the mass. Fat and muscular components were not present. Therefore chondromatous tumor of the breast was diagnosed.- - - - - - - - - - ranking = 0.0032313810941043keywords = lower (Clic here for more details about this article) |
3/32. Chondromyxoid fibroma of the upper thoracic spine in a 7-year-old patient. A case report and review of the literature.BACKGROUND: We report a case of a 7-year-old white female who presented with acute, progressive bilateral lower extremity weakness over 48 h. methods: Case report and presentation of clinical, radiological and pathological data on a single case of chondromyxoid fibroma (CMF) of the T2 vertebral body. RESULTS: magnetic resonance imaging of the thoracic spine revealed an extensive mass invading the lamina of the second thoracic vertebra, causing extensive cord compression and progressive neurological deterioration. Surgical resection and pathologic study of the mass revealed a CMF. CONCLUSIONS: A thorough medline search has revealed that only 25 cases of spinal CMF have been reported, making this lesion an extremely rare bone tumor.- - - - - - - - - - ranking = 0.0032313810941043keywords = lower (Clic here for more details about this article) |
4/32. Chondromyxoid fibroma of the mandible. Diagnostic image cytometry findings and review of the literature.A case of chondromyxoid fibroma in the mandible of a 12-year-old boy is reported. A review of the literature is presented with emphasis on flow and image cytometric analysis and evaluation of the radiologic and histologic differences between chondromyxoid fibroma and chondrosarcoma.- - - - - - - - - - ranking = 5keywords = mandible (Clic here for more details about this article) |
5/32. Genochondromatosis.We report a new disorder that we have called genochondromatosis. Four patients from the same family with the characteristic localisation of chondromatosis (clavicle, upper end of humerus, and lower end of femur) were investigated. The favourable course, the dominant transmission, and previous publication of similar cases confirm the uniqueness of this new entity. The chondrodysplasias with disorganised development of cartilage are far from being completely understood. Recently, several disorders within this group have been well defined, including metachondromatosis and spondyloenchondroplasia, but there still remain numerous clinical subgroups that are very difficult to classify.- - - - - - - - - - ranking = 0.0032313810941043keywords = lower (Clic here for more details about this article) |
6/32. Osteocartilaginous tumors in the parapharyngeal space arising from bone exostoses.Three osteocartilaginous tumors that arose from bone stalks were diagnosed by the demonstration, on multiplanar cross-sectional CT and MR images, of the site of stalk attachment to the adjacent mandible (one), skull base (one), and cervical vertebra (one). All three patients presented with signs and symptoms related to mass effect in the parapharyngeal region. Mass effect was more pronounced in the two cases of malignant degeneration (osteosarcoma, chondrosarcoma) than in the single case of benign osteocartilaginous exostosis. Differentiation of benign from malignant osteocartilaginous tumor may be accomplished by appreciating characteristic CT and MR features of the cartilage cap. The differential diagnosis of mass lesions of the parapharyngeal space should include tumors of osteocartilaginous origin.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
7/32. Odontogenic keratocyst associated with an intramandibular chondroma.The unusual feature of an intramandibular chondroma in association with an odontogenic keratocyst in a 59-year-old man is described. The keratocyst recurred and required two reoperations. The coexistence of an odontogenic keratocyst and a chondroma of the jaw was probably a coincidence of two simultaneous but otherwise unrelated lesions. The possibility that the keratocyst and the chondroma were due to a single developmental disturbance of the region cannot be excluded. No signs of a recurrence were seen at the last follow-up examination four years after the operation.- - - - - - - - - - ranking = 0.38950972576531keywords = jaw (Clic here for more details about this article) |
8/32. osteochondroma of the mandibular condyle. Case report and its management.1. A case of osteochondroma of the temporomandibular joint simulating a unilateral condylar hyperplasia is presented. 2. The need to divide the zygomatic arch to facilitate removal of large tumors is noted. 3. The removal of the growth resulted in normal functioning of the jaws with the disappearance of the features of unilateral hyperplasia. 4. Occlusal grinding is often necessary to correct the compensatory occlusal adjustment that occurs with the rotation of the mandible in these lesions. 5. The possibility of the presence of a tumor must be kept in mind when patients present with symptoms of unilateral condylar hyperplasia.- - - - - - - - - - ranking = 1.3895097257653keywords = mandible, jaw (Clic here for more details about this article) |
9/32. osteochondroma of the coronoid process of the mandible.A case of osteochondroma of the coronoid process is presented. The proper diagnosis of ill-defined symptoms in the temporomandibular joint requires conformity between clinical manifestations and radiologic findings. The importance of a thorough radiologic examination is stressed for the correct diagnosis of these rare, insidious, slow-growing tumors. A short review of the literature is presented, and the treatment and surgical approach to these tumors are discussed.- - - - - - - - - - ranking = 4keywords = mandible (Clic here for more details about this article) |
10/32. Osteochondromatous exostosis of the condyle.Osteochondromatous exostosis of the condyle is rare. When these exotoses become large, they can cause temporomandibular pain and clicking with mandibular movements. Treatment consists of surgical removal of the mass. Adjunctive care may include use of intermaxillary fixation, training elastics, and jaw exercises.- - - - - - - - - - ranking = 0.38950972576531keywords = jaw (Clic here for more details about this article) |
