Thoracobiliary fistula is a rare complication of hydatid cyst of the liver especially in the calcified form. Surgery is the only medical option. The treatment consists of radical surgical procedures in the majority of the patients. Conservative surgical treatments are performed with high mortality rate. Herein, we will describe two patients of calcified hydatid cysts of the liver whose conditio...

calcifying epithelial odontogenic tumor (ceot) is a rare benign, but locally infiltrating odontogenic neoplasm. it accounts for less than 1% of all odontogenic tumors. this is a case report of recurrent ceot in the maxilla. a 35-year-old patient reported after three years of surgical excision of the lesion, with a recurrence. it is of particular concern because of its anatomic location in the m...

There are several treatment modalities to date for central giant cell granuloma including conservative treatment and surgical treatment with often planned reconstruction of the bony defect. Spontaneous bone regeneration of mandibular defects following complete resection of mandible has rarely been reported in the literature. We report a case of spontaneous bone formation after resection of a ce...

OBJECTIVE Prognosis of primary thymic carcinomas is poor due to advanced stage progression at diagnosis and highly malignant behavior. We retrospectively evaluated patients with thymic carcinoma to determine the prognostic factors. METHODS Sixty patients diagnosed and treated for thymic carcinoma from 1986 to 2005 were reviewed retrospectively. Influences of demographic characteristics, Masao...

OBJECTIVES This study aims to evaluate the alterations in distances to the surgical margins on sheep tongue specimens, through resection, formalin fixation, frozen section, and microscopic examination. MATERIALS AND METHODS Fifty fresh sheep tongues were used in the study. A metal plate was fixed on the lateral aspect of each tongue to represent tumor tissues. A total of 40 specimens with eit...

BACKGROUND Due to the adenoma-carcinoma sequence, complete removal of colorectal polyps is essential. METHOD This article analyzes the role of surgery in the removal of colorectal adenoma. RESULTS Nowadays, most adenomas are removed properly by endoscopic methods. Also in the resection of giant polyps and recurrent adenoma endoscopic data is convincing. Therefore, surgical resection of colo...

METHODS A total of 174 patients underwent resections for aerodigestive tract invasion from differentiated thyroid cancer (103 patients), medullary thyroid cancer (40 patients), and undifferentiated thyroid cancers/unusual thyroid neoplasms (31 patients). In all, 82 patients submitte...

Within the surgical treatment of glioma, extended survival is predicated upon extent of resection which is limited by proximity and/or invasion of eloquent structures. Diffusion tensor imaging (DTI) tractography is a very useful tool for guiding supramaximal surgical resection while preserving eloquence. Although gliomas can vary significantly in size, shape, and invasion of functionally signif...

Brain metastasis is a devastating complication of systemic malignancy that affects a considerable number of cancer patients. The appearance of brain metastases is often considered to be a sign of poor prognosis; in patients with brain metastases poor survival time has been reported in the literature. Therefore, treatment of these brain lesions in cancer patients is important for quality of life...
