Tumors or cancers of the KIDNEY.
Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event.

Multi-bracket appliance in management of mandibular reconstruction with vascularized bone graft. (1/281)

BACKGROUND: The most commonly used tool for maxillo-mandibular fixation to the patient who underwent reconstruction using a vascularized bone graft after mandibular resection is a dental arch-bar. However, the occlusal relationship achieved by this method is not ideal. Different from the dental arch-bar, the multi-bracket appliance which is frequently used in orthodontic treatment can control the position of each individual tooth three dimensionally. Thus, this appliance was applied for maxillo-mandibular fixation to patients who underwent mandibular reconstruction using a vascularized bone graft. METHODS: A multi-bracket appliance was applied to three patients. Prior to the surgery, standard edgewise brackets were bonded to the teeth in the maxilla and in the remaining mandible. After mandibular resection, wires for maxillo-mandibular fixation were applied. The harvested bone was then carefully fixed with miniplates to maintain the occlusion. The multi-bracket appliance was worn for 3 months when the wound contraction became mild. RESULTS: All three cases demonstrated stable and good occlusion. They also demonstrated satisfactory post-surgical facial appearance. CONCLUSIONS: Compared to conventional dental arch-bars, a multi-bracket appliance offers improved management of mandibular reconstruction. Firstly, its properties are helpful in maintaining occlusion of the remaining dentition accurately in bone grafting procedure as well as protecting against postsurgical wound contraction. Secondly, the multi-bracket appliance keeps the oral cavity clean without periodontal injury. As a result, stable occlusion of the residual teeth and good facial appearance were obtained.  (+info)

Cemento-ossifying fibroma presenting as a mass of the parapharyngeal and masticator space. (2/281)

We report a case of cemento-ossifying fibroma that presented as a large extraosseous mass in the masticator and parapharyngeal space. CT scanning and MR imaging showed a large extraosseous mass with central conglomerated, well-matured ossified nodules and fatty marrow. The central matured ossified nodules were of low density on CT scans and high signal intensity on T1- and T2-weighted MR images. Multiplanar reformatted CT scans revealed the origin of the mass to be at the extraction site of the right lower second molar tooth.  (+info)

Skull metastasis of Ewing's sarcoma--three case reports. (3/281)

Three cases of skull metastasis of Ewing's sarcoma were treated. The metastatic lesion was located at the midline of the skull above the superior sagittal sinus in all cases. Surgery was performed in two patients with solitary skull lesions involving short segments of the superior sagittal sinus without remarkable systemic metastasis, resulting in good outcome. The third patient had extensive, multiple tumors involving the superior sagittal sinus which could not be excised, and died due to intracranial hypertension. The surgical indication for skull metastasis of Ewing's sarcoma depends on the location and length of the involved superior sagittal sinus, and general condition.  (+info)

The relationship between accessory foramina and tumour spread on the medial mandibular surface. (4/281)

The medial cortical surface of the mandible can be involved by tumour infiltration from the floor of the mouth. A detailed study of spread via accessory foramina through the edentulous alveolar crest has been previously undertaken, but no similar study has been carried out for the medial surface. In order to gain further appreciation of the mode of tumour spread, a study of the number and distribution of accessory foramina on the medial mandibular surface was performed on 89 mandibles. The number of foramina varied greatly from specimen to specimen. In the ascending ramus above the inferior dental foramen, 3 mandibles showed no foramina; the condylar section possessed the greatest proportion followed by the sigmoid and the coronoid. On the rest of the medial surface below the inferior dental foramen, all specimens showed at least 1 accessory foramen; the greatest concentration was in the middle third along the path of the inferior dental canal, followed by the upper third and the lower third section. Accessory foramina were repeatedly present at certain dedicated sites. The medial facing wall of the inferior dental foramen was found to be the commonest dedicated site (98.3%) followed by foramina on either side of the genial tubercles (71.9%), the digastric fossa (71.9%) and the median foramen above the genial tubercles (64%). The findings of this study are in keeping with the current observation that the lower border is least commonly involved in tumour spread. In view of the presence of accessory foramina along the inferior dental canal and especially on the medial facing wall of the inferior dental foramen, it is imperative to preclude tumour spread in this region prior to undertaking the conservative rim resection procedure. Medial to the symphysis the alveolar mucosa dips down almost to the level of the dedicated foramina in the vicinity of the genial tubercles. As a general rule the attached muscle forms a barrier to tumour spread except in the later stages, however, in irradiated mandibles resistance to spread has been previously reported to be diminished. Under these circumstances, it is possible that the numerous accessory foramina reported in this study could facilitate a direct pathway into the cancellous bone.  (+info)

Amyloid-producing odontogenic tumor in a Shih-Tzu dog. (5/281)

A 9-month-old male Shih-Tzu dog had a right mandibular tumor composed of strands, or nest-like proliferation of epithelial cells with abundant fibrous stroma characterized by spheroid to large nodular deposition of amyloid with Congo-red stain. Globule calcification was also seen throughout the tumor tissue and the spheroid depositions often had a concentrically laminated structure (Liesegang rings). The case was diagnosed as amyloid-producing odontogenic tumor in a dog.  (+info)

Intraosseous neurilemmoma of the mandible. (6/281)

We report a rare case of intraosseous neurilemmoma of the mandible, with an emphasis on radiographic findings. The tumor, located mainly in the premolar region, presented as an expansive, unilocular, well-defined, radiolucent lesion on plain radiography. No dilatation of the mandibular canal was identified. MR imaging helped to identify the solid nature of the tumor. A biopsy was necessary to make the final diagnosis because of the relatively nonspecific nature of the lesion.  (+info)

Ewing's sarcoma of the head and neck. (7/281)

CONTEXT: Ewing's sarcoma is a rare neoplasm, which usually arises in long bones of the limbs and in flat bones of the pelvis, with the involvement of head and neck bones being very unusual. CASE REPORT: a case of Ewing's sarcoma occurring in the mandible of a 35-year-old female. Pain and swelling of the tumor were the main complaints. The early hypothesis was an undifferentiated malignant neoplasm, possibly a sarcoma. The CT scan depicted an expansive lesion, encapsulated, with septa and characteristics of soft tissue, involving the left side of the mandible and extending to the surrounding tissues. The patient underwent surgical excision of the lesion, the definitive diagnosis of Ewing's sarcoma was established, and the patient commenced on radiotherapy.  (+info)

Aggressive epithelial odontogenic ghost cell tumor in the mandible: CT and MR imaging findings. (8/281)

We report a case of aggressive epithelial odontogenic ghost cell tumor arising from the mandible in a 32-year-old man. On CT and MR studies, the tumor was seen as a large, heterogeneous soft-tissue mass that caused marked destruction of the mandible and invaded the mouth floor and tongue base. The tumor displayed a variety of densities and signal intensities on CT and MR images, which correlated well with the degree of cellularity of epithelial islands, abundance of ghost cells and eosinophilic materials, calcification, and cystic areas on histologic sections. Owing to the unpredictable biological behavior of this type of tumor, careful, long-term follow-up is highly recommended.  (+info)

INTRODUCTION: Ameloblastic fibro-odontosarcoma is an extremely rare subtype of odontogenic sarcoma, with only 13 cases reported in the literature.. CASE REPORT: A 4-year-old male presented with a painless mandibular swelling, which appeared 4months previously. Cone beam computed tomography revealed an extensive, ill-circumscribed, multilocular radiolucency of the right mandible extending from the first deciduous molar to the ramus with slightly dense opacities. Histological examination of the incisional biopsy specimen revealed a biphasic tumor with sarcomatous mesenchyme and benign ameloblastic epithelial component compatible with a diagnosis of ameloblastic fibrosarcoma. A right hemimandibular resection was performed. Areas of deposition of dentinoid and enamel material closely adjacent to ameloblastic epithelium were noted in the excised specimen. A final diagnosis of ameloblastic fibro-odontosarcoma was made. After four years of close follow-up, there is no sign of recurrence or ...

Impaired wound healing may result from a combination of co-morbidities such as diabetes, peripheral arterial disease, radiation, immunosuppression or infection [8]. In our case, two chronic oro-cutaneous fistulas resulting from tumor excision on the right mandible, multiple reconstructive procedures, radiation and one cycle of chemotherapy closed after application of autologous, concentrated ASC into the surrounding fistula tissue.. Since ASC were described in 2001 they have gained particular attention among clinicians due to their extraordinary characteristics (i.a. promotion of neovascularization, secretion of growth factors, anti-inflammatory properties) besides being easily accessible and applicable [8], [9]. Still, to our knowledge, there are only few studies and cases reporting the usage of autologous/allogeneic ASC for chronic wounds in humans [3], [4], [5], [6], [10]. Garcia-Olmo et al. recently published the results of a phase III randomized multicenter clinical trial comparing ASC with ...

Although an odontoma is a type of tumor, the tissue is benign, which means that it will not normally become cancerous. In fact, dentists often discuss this condition as a type of hamartoma, which is simply an abnormal growth (in this case) of dental tissue.. Risk factors. An odontoma will normally develop in children and young teens, as the problem generally occurs when the primary teeth form. A complex odontoma can also affect adults, and research shows that the condition can affect both men and women.. 60 percent of compound odontomas form in the canine area, and a similar proportion of complex odontomas form in the molars.. Symptoms. An odontoma will not normally cause any pain or discomfort. Sometimes, the growth may inhibit tooth development, which may eventually cause some irritation, but dentists generally only spot the condition when they take a routine dental X-ray.. Nonetheless, other dental problems may point to a problematic odontoma. For example, the condition can sometimes stop a ...

This retrospective study was designed to evaluate subjects treated for mandibular lesions with segmental resection in the oral and maxillofacial surgery clinic of the study institution between June 1992 and May 2015, and thereafter to characterize those who developed spontaneous bone regeneration. The cases of 636 patients were evaluated. The study was granted an exemption in writing from ethical clearance by the research and ethics committee of the institution because of the retrospective design. All known patients who presented spontaneous bone regeneration within this period were included in the study. The diagnosis of spontaneous bone regeneration was made postoperatively, during routine clinical and radiographic follow-up examinations of the surgical sites. Information obtained from the hospital register, case files, and plain radiographs of the subjects were recorded in a pro-forma questionnaire designed for the study. The following information was recorded: age, sex, type of mandibular ...

N2 - Type IV collagen, the major component of basement membrane (BM), demonstrates a stage- and position-specific distribution of its isoforms during tooth development. To determine its localization in BM of odontogenic neoplasms, immunohistochemistry using six anti- a (IV) chain-specific monoclonal antibodies was performed. Expression of a 1(IV)/ a 2(IV) and a 5(IV)/ a 6(IV) chains was stronger in the desmoplastic than in ordinary ameloblastomas. The adenomatoid odontogenic tumor distinctly expressed these chains in BM of cribriform areas and hyaline materials (which was also a 4(IV)-positive. These five chains also stained BM and tumor cells of ameloblastic fibroma. Present results suggest that collagen IV composition and ...
Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic neoplasm of the jaw. AFS is characteristically composed of a benign odontogenic epithelium and a malignant mesenchymal component. The posterior region of the mandible is the predominantly occupied site. In the present report, a new case of AFS in a 22-year-old male that originated from ameloblastic fibroma was described. Histologically, the tumor showed biphasic components: Benign epithelium and a malignant mesenchymal component. Immunochemical findings revealed that the tumor cells were positive for cluster of differentiation (CD) 34, vimentin, Ki-67 and p53, but negative for smooth muscle actin, S-100, CD68 and desmin ...
With the disease being extremely rare, clinicians have to rely on various reported cases for guidance. Hence, the establishment of treatment standards is not possible. Radiotherapy has been controversially discussed in the past. Most reported cases underwent surgical removal.. Reports of ameloblastic carcinomas receiving radiation therapy are scarce and mostly from the pre-3 D and cobalt era [9-11]. To our knowledge, radiotherapy has only been given as adjuvant therapy in only a few cases [11-15] within the past 20 years. Radiation doses between 41,4 Gy and 54 Gy have been comparatively conservative [12, 13, 16] or not been reported [2, 14, 17] leading to local relapse in half of the cases. Higher radiation doses between 66 and 72 Gy in close margin/positive-margin resections as reported by Philip et al [15] lead to local control for the duration of available follow-up (0.8 - 3.3 years) in the reported 3 cases.. While it has been discussed in cases with incomplete resections or nodal metastases, ...
INTRODUCTION: Cases of maxillary ameloblastomas from 15-year database (1986-2000) collected in the Department of Cranio-Maxillofacial Surgery of the University Hospital of Zurich were evaluated. PATIENTS: Twenty-six patients suffering from ameloblastoma had been collected. Five of them, had a maxillary ameloblastoma, three females and two males. METHODS: A clinical retrospective study was performed. In addition a review of the literature was undertaken and the findings have been compared and contrasted. PATIENTS: The overall incidence of ameloblastoma within the mandible (21) was four times higher than in the maxilla (5). In 69 per cent of the cases (18) it occurred in men, in 31 percent (8) in women. The sex ratio differed with the maxillary ameloblastomas: 40 percent male (2) and 60 per cent female (3). Although slow growing and nearly painless, it can reach a considerable size within the mid-face involving such highly specialized structures as the orbit, skull-base and brain. Wide resections ...

INTRODUCTION: Odontogenic myxoma (OM) is a benign neoplasm of mesenchymal origin with growth characteristics, clinical behaviour and radiographic presentation similar to those of ameloblastoma. It is an intraosseous neoplasm characterized by stellate and spindleshaped cells embedded in loose myxoid or mucoid extracellular matrix. Although sometimes bony islands that represent residual trabeculae are found throughout the lesion, the formation of osteocement-like calcified spherules within the tumour is an extremely rare phenomenon. REVIEW: We report a very rare case of an OM of the left maxilla exhibiting osteo-cementous metaplasia within the substance of the tumour and beyond the facial skeleton, in the nasopharynx. A review of all four similar cases previously reported in the literature is also presented. CONCLUSION: Whether or not this property to produce significant amounts of bone can be associated with a different biological behavior for this specific variant of OM remains to be proved with ...

Ameloblastoma (from the early English word amel, meaning enamel + the Greek word blastos, meaning germ) is a rare, benign or cancerous tumor of odontogenic epithelium (ameloblasts, or outside portion, of the teeth during development) much more commonly appearing in the lower jaw than the upper jaw. It was recognized in 1827 by Cusack. This type of odontogenic neoplasm was designated as an adamantinoma in 1885 by the French physician Louis-Charles Malassez. It was finally renamed to the modern name ameloblastoma in 1930 by Ivey and Churchill. While these tumors are rarely malignant or metastatic (that is, they rarely spread to other parts of the body), and progress slowly, the resulting lesions can cause severe abnormalities of the face and jaw. Additionally, because abnormal cell growth easily infiltrates and destroys surrounding bony tissues, wide surgical excision is required to treat this disorder. If an aggressive tumor is left untreated, it can obstruct the nasal and oral airways making it ...

A glomus tumor is a rare neoplasm usually found in the dermis or subcutaneous tissue of the extremities. It is rare for the glomus tumor to occur on the head and face. Only 26 glomus tumors of the oral region and affected bone have been reported in the English-language literature (Table 1). We report a case of a glomus tumor at the mandible. As a new point, the glomus tumor resorbed a bone and teeth roots when the tumor progressed into the mandible. The patient was a 44-year-old Japanese man who complained swelling of the right mandible. Radiographic examination showed a multilocular radiolucency area in the left mandible. Radiographic findings on our case resembled those of a common benign tumor. The lesion occupied to the premolar and molar area and revealed that the tumor resorbed the roots of the teeth.

Only 26 glomus tumors of the oral region and affected bone have been reported in the English-language literature (Table 1). We report a case of a glomus tumor at the mandible. As a new point, the glomus tumor resorbed a bone and teeth roots when the tumor progressed into the mandible. The patient was a 44-year-old Japanese man who complained swelling of the right mandible. Radiographic examination showed a multilocular radiolucency area in the left mandible. Radiographic findings on our case resembled those of a common benign tumor. The lesion occupied to the premolar and molar area and revealed that the tumor resorbed the roots of the teeth. The lesion was removed surgically with the buccal cortical bone and buccal mucosa in contact with the mass of the tumor. The mass fully excised intraorally under general anesthesia, and the inferior
Based on the clinicopathological, microscopic, and immunohistochemical staining features and the absence of a primary tumor at a distant site, we propose that the lesion in this cat be diagnosed as a solid type PIOSCC. In human medicine, PIOSCC is a rare oral tumor, representing less than 2% of all oral SCCs in people [8-10]. The majority of PIOSCCs arise from other benign odontogenic tumors or cysts, while solid de novo type PIOSCC is extremely rare [11, 12]. Although PIOSCC has not yet been described in cats, in the clinical case presented here, the radiographic and microscopic features were very similar to those described for human solid type PIOSCC. Namely, the cat presented with very non-specific clinical signs in which the major complaint was an autotraumatic superficial skin lesion on the chin. Given the findings of the extensive oral examination, it was considered likely that the lesion was a result of pain or discomfort arising from the oral cavity. Although solid type PIOSCCs in humans ...

The external face operation in our example fails because some important global information is missing from the local processing. The processes need some data that is not local to them, but they do not need all the data. They only need to know about cells in other partitions that are neighbors to the local cells. We can solve this local/global problem with the introduction of ghost cells. Ghost cells are cells that belong to one partition of the data and are duplicated on other partitions. The introduction of ghost cells is performed through neighborhood information and organized in levels. For a given partition, any cell neighboring a cell in the partition but not belonging to the partition itself is a ghost cell 1. Any cell neighboring a ghost cell at level 1 that does not belong to level 1 or the original partition is at level 2. Further levels are defined recursively. We define ghost cells in this way because it provides a simple distance metric to the cells of a partition and allows filters ...

Excisional or incisional biopsy. This type of biopsy is often used when a wider or deeper portion of the tissue is needed. Using a scalpel (surgical knife), a full thickness of skin or all or part of a large tumor may be removed for further examination. The wound is sutured closed (with surgical thread).. When the entire tumor is removed, it is called excisional biopsy. If only a portion of the tumor is removed, it is called incisional biopsy. For instance, excisional biopsy is the method usually preferred when melanoma is suspected. Both types of biopsies can be done by using local or regional anesthesia. If the tumor is inside the chest or abdomen, general anesthesia is used. Under some circumstances, surgeons will take an excisional or incisional biopsy that goes immediately to the pathologist while the patient remains under anesthesia, ensuring complete excision of a tumor. ...
