Neuroendocrine carcinoma of tongue : a case report with review of literature INTRODUCTION Neuroendocrine carcinomas (NECs) are rare in the oral cavity, especially in the tongue. There is ambiguity with respect to the classification and treatment modality of these tumors. To the best of our knowledge, only 10 cases regarding to the NECs in tongue have been reported in English literature. We present a case of Neuroendocrine tumor of the tongue and the related literature was reviewed with the purpose of providing certain reference for the diagnosis and treatment of such rare entities. CASE PRESENTATION A 38 year old Chinese man initially presented to our department with one month history of a non-tender, firm lump and odynophagia in the left
Metachronous Multicentric Giant cell tumor: a case report ABSTRACT Multicentric giant cell tumors represent less than 1% of all giant cell tumors of bones. We report a case of young girl with metachronous multicentric giant cell tumors with 5 documented lesions in a monomelic lower limb. The initial lesion started during the first trimester of her pregnancy around her right pelvis and resulted in rapidly progressive painful swelling with restricted mobility of her right hip joint. These tumors had typical radiological appearance and the diagnosis of giant cell tumor was confirmed on histopathology. She was managed by an aggressive surgical approach for knee and talar lesions, whereas repeated embolization was done to treat her pelvic lesion.
First of them is hematogenious spreading and the other one is directly planting which is more commonly seen at genitourinary tumors(3). According to 25 yeared clinicopathological study of Lam KY et al; most common primary tumors metastas to spleen: breast (22.9%), lung (20.2%), colon and rectum (9.4%), ovary (9%), stomach (6.9%) and skin (esp. malignant melanoma-5%). According to same study metastasis from liver cancers are 2.8%(16). İn our case malignancies can metastate to spleen were excluded.
Approximately % 10 of all cancer patients develop spinal metastases (3) Half of all metastases in the spine is in the thoracic vertebra, followed by the lumbar and cervical vertebra (4,5,6). When an involvement occurs in the spine, vertebral body is the most frequent site ( followed by the pedicles and posterior elements ) and often leads to pathologic fracture (7). Plexus of Batson is used by malignant cells via hematogenous spread by virtue of lacking valves (8) The vertebral involvement in cancer patients deteriorates the course of the malignancy and not only reduces the patients quality of life but also increase the ratio of mortality. One of the determinants of the low quality of life in cancer patients that mentioned above is the pathologic fracture of the vertebra. It is reported that the incidence of pathologic fractures of the vertebra in patients with malignancy is approximately % 10 (9).
Mirilpublished the earliest unequivocal case of renal carcinoma in 1810. Koenig published the first classification of renal tumours based on macroscopic morphology in 1826. Causes: The cause of kidney cancer is not known. But certain factors appear to increase the risk of getting kidney cancer. Kidney canceroccurs
Carcinoid tumors may sometimes be asymptomatic, but in a certain number of patients they may present with certain symptoms. The signs of the illness are not definite and depend significantly on the location of the tumor. Hormones released into the blood by one out of ten carcinoid tumors are responsible for causing the symptoms of the illness. Factors including stress, heavy exercise, and alcohol consumption lead to symptoms in several patients with carcinoid tumor. Food containing tyramines (such as chocolate, blue cheese, red wine or red sausage) may also provoke characteristic symptoms.
INTRODUCTION: Adenoid cystic carcinoma is a rare epithelial tumour, and comprises about 1% of all malignant tumours of the oral and maxillofacial region. It is a malignant tumour which may develop in the trachea, bronchus, lungs or mammary glands, in addition to the head and neck region.1 The clinical and pathological findings typical of this tumor include slow growth, perineural invasion, and potential local
Brain tumor diagnosis is often incidental to other areas of the brain. Predictions on the growth rate of this specific type of tumor differs and there is no precise method to convey how long the tumor was developing before diagnosis. Most meningiomas do not spread to other parts of the brain. This classification of brain tumor is usually found at one particular site however an individual may have several tumors in varying parts of the brain tumor and spinal cord. Consequently, when meningiomas are identified multiple treatments may have to
The patient had recurrence and the cause of death was renal failure. The disease free survival in this study group was 82% after one year. 8 patients developed recurrence (7 developed local recurrence and one had distant metastasis).Cervix was the most common site of recurrence brain was the site of distant metastasis. There is significant reduction of the size of the tumor after concurrent chemo radiation. In the present study, 26(57.8%) patients were stage 2B,1(2.2%) patient was stage
The tumor is represented in 3D by using a bounded volume box of shapes ellipsoid, sphere. The location where it presents is marked in the 3d triangular mesh breast model. V. Ramalingam et al  proposed a method of segmenting the masses using only the single view image i.e. either CC or MLO view. Initially, the image is preprocessed to remove the artifacts, pectoral muscle and noise.
