1/27. Orbital extension of a frontal sinus osteoma in a thirteen-year-old girl.Osteomas are uncommon, slow-growing, benign osteogenic neoplasms that arise most frequently in the craniofacial skeleton. (1,2) osteoma is the most common benign tumor of the nose and paranasal sinuses and the most common neoplasm of the frontal sinus. (3-5) Paranasal sinus osteomas originate in the sinus wall, fill the lumen with well-defined mature osseous tissue, and occasionally extend into the orbit where they give rise to orbital signs and symptoms. Osteomas most commonly become symptomatic in the second to fifth decade in life, but orbital involvement has rarely been reported in patients aged 18 years and younger. (2,6-10) We report a case of a frontal sinus osteoma with orbital extension in a 13-year-old girl.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/27. Mandibular and temporomandibular joint arthropathy in the differential diagnosis of the parotid mass.OBJECTIVE: To increase awareness of temporomandibular joint and mandibular disease in the overall evaluation and diagnosis of the parotid mass. STUDY DESIGN: We describe clinical presentations of pigmented villonodular synovitis and synovial chondrocalcinosis of the temporomandibular joint, as well as osteoma of the mandible, as they may initially suggest primary neoplasms of the parotid gland. CONCLUSIONS: Preauricular swelling is a common presenting symptom for patients visiting an otolaryngologist. Often this symptom is suggestive of a parotid mass. However, lesions of the temporomandibular joint and mandible may also present in this fashion.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
3/27. Solitary intracranial subdural osteoma: case report and review of the literature.Intracranial subaural osteomas without any relation to osseous or meningeal tissues are rare, with only five cases including the present one having been reported so far. In most patients headache, which was always localized at the site of the lesion, was the most frequent complaint and subsided after complete resection of the neoplasm. The mechanism of origin of such lesions remains unknown.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
4/27. Uncommon peripheral osteoma of the mandible: report of two cases.The osteoma is a benign osteogenic neoplasm of bone. Peripheral osteoma of the mandible is uncommon. It is often asymptomatic and usually discovered when a patient complains of esthetic problems and presents for treatment. Peripheral osteomas have a characteristic clinical and radiographic appearance, but their pathogenesis is obscure. Described here are two patients with peripheral osteoma of the mandible, which might occur as a result of a combination of trauma and muscle traction.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
5/27. Giant ossifying fibroma. Case report on a bimaxillary presentation.Ossifying fibroma is a slow-growing, benign neoplasm, but some lesions behave aggressively, reaching massive proportions, thus demanding special treatment. The following case report holds particular interest, because of the simultaneous occurrence of an active ossifying-cementifying fibroma in the maxilla and mandible with the maxillary lesion attaining enormous size.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
6/27. mastoid osteomas: report of two cases.OBJECTIVE: To discuss the differential diagnosis of two cases with mastoid mass. STUDY DESIGN: Case report and review of the literature. SETTING: The study was carried out in Gulhane Military Medical Academy, Haydarpasa Training Hospital, Istanbul, turkey. PATIENT, INTERVENTION, AND RESULTS: Both cases were 23-year-old males. They admitted to our clinic with masses behind their left ears that had been progressively enlarging for 5 years. In both cases, coronal and axial computerized tomography scans revealed a wide-based lesion involving temporal bone cortex. The cases were operated on for diagnosis and for correction of the cosmetic deformity. Histopathological examinations were consistent with mixed and spongiotic osteoma. CONCLUSIONS: mastoid osteoma is a rare, benign tumor of bone. It may cause cosmetic deformity such as external mass or an auricular protrusion. Other neoplasms of the mastoid region, such as osteosarcoma and osteoblastic metastasis, should be considered for the differential diagnosis.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
7/27. Benign osteoma with gardner syndrome: review of the literature and report of a case.gardner syndrome, a variant of familial adenomatous polyposis, is an autosomal dominant disease characterized by gastrointestinal polyps that develop in the colon as well as in the stomach and upper intestine (duodenum), multiple osteomas, and skin and soft tissue tumors. Cutaneous findings include epidermoid cysts, desmoid tumors, and other benign tumors. polyps have a 100% risk of undergoing malignant transformation; consequently, early identification and therapy of the disease are critical. osteoma is a benign neoplasm of bone tissue that is characterized by slow continuous growth and is the most common accompanying bone lesion seen in gardner syndrome. The authors report a case of gardner syndrome that was operated on because of the mandibular osteoma.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
8/27. Peripheral osteoma of the mandibular condyle.Osteomas are benign bone neoplasms, classified as either peripheral or central. The peripheral variant is rare, with only six cases reported involving the mandibular condyle, that are not related to gardner syndrome. The seventh case of peripheral osteoma involving the mandibular condyle is reported in this paper.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
9/27. Peripheral osteoma of the mandible: case report and review of the literature.BACKGROUND: osteoma is a benign often asymptomatic neoplasm, consisting of well-differentiated mature bone. This paper reports a case of peripheral osteoma located in the anterior mandibular region and provides a review of the literature about this lesion in the jaws. PATIENT AND methods: A 43-year-old white woman presented with a swelling in the left mandible of 7 years duration. The English literature was reviewed over the past 76 years and data about location, histopathology and number of the peripheral osteomas, sex, and age of the patients were evaluated. RESULTS: Data analysis showed 69 well-documented cases of peripheral osteoma. Peripheral osteomas are more frequent in the mandible than the maxilla and the cancellous type was most frequent; males and females are equally affected in the mandible; the age range was 9-85 years. CONCLUSION: The peripheral type of osteoma is most common in the lower jaws, occurs at the surface of the cortical bone and is sessile or pedicled.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
10/27. A huge osteoma of the middle ear.Osteomas of the middle ear are rare benign neoplasms. Most of the cases caused conductive hearing loss and others were asymptomatic and diagnosed incidentally. We report a case of a huge middle ear osteoma along with compatible radiological findings filling the whole tympanum and the eustachian tube, which caused intermittent otorrhea and conductive hearing loss.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
