ABSTRACT
Objectives: To evaluate the surgical approaches and prognosis of thyroid carcinomas invading the adjacent structures
Methods: The medical records of 197 patients with a pathology diagnosis of thyroid cancer were retrospectively reviewed
Results: Seventeen patients [9%] with thyroid carcinoma invading surrounding structures were included. Patients were initially divided into two groups on the basis of tumor histology: papillary [Group A] and nonpapillary [Group B]. Then patients were divided into three groups Group 1: patients who underwent total thyroidectomy Group 2: patients who underwent total thyroidectomy with shaving resection Group 3: patients who underwent total thyroidectomy with extensive surgery. All patients who didn't survive were more than 45 years old. The survival rate was statistically better in group A compared to group B [92% versus 20%]. The survival rate decreased from Group 1 through Group 3, without reaching statistical significance
Conclusions: Age and histologic type are important in determining the prognosis of locally invading thyroid cancer

To analyze the characteristics and management of parotid tumors in a tertiary care center
Study design: Retrospective cohort study
Methods: All cases of parotid tumors [or masses] in our department between Jan 1, 1999 and December 31[st], 2012 were studied. Demographic data, clinical characteristics, histopathology and management were analyzed. We also evaluated the diagnostic value of fine needle aspiration cytology [FNAC] in our center
Results: Of the 216 parotid tumors, 164 underwent parotidectomy and 52 were not managed surgically; 73.1% had a benign tumor [36.6% had Warthin's tumor] and 16.7% had a malignant one. In our center, FNAC was found to have a sensitivity for reporting malignancy of 71.4% and a specificity to rule in malignancy of 100%
Conclusion: In our series, Warthin's tumor was the most frequent mass probably related to the high tobacco use. The prevalence of malignant tumors was relatively high in our series. Primary malignant tumors and pleomorphic adenomas should always be treated surgically, however, lymphomas, metastatic and benign inflammatory masses and cases of Warthin's tumors could be managed nonsurgically
ABSTRACT
Ameloblastoma is a benign neoplasm derived from residual epithelial components of tooth developpment considered by most authors as a benign, rare and locally aggressive tumor with potential of transformation into a malignant tumor. We report in this article the transformation of an ameloblastoma to an ameloblastic carcinoma. An analytic description of the elements of the diagnosis is proposed in addition to the therapeutic procedure which was adopted
