To the Editor—We read with interest the paper on fineneedle aspiration cytology (FNAC) of thyroid nodules in a regional hospital setting by Cheung et al.1 We reported our findings in a private setting in this journal in 1999.2 It is difficult to compare the two studies due to the exclusion of follicular tumours from their statistical analysis. Unlike FNAC of other organs, FNAC of the thyroid sh...

Most of these tumors are benign hyperplastic or colloid nodules or benign follicular adenomas. However, 5% to 10% of the lesions that come to medical attention are carcinomas. A major clinical challenge is establishing which nodules are hyperplastic, benign, or malignant. History, ...

background and objectives: rcc is one of the most common genitourinary cancers. accurate prediction of prognosis would be valuable for adjuvant trial design, counseling and effectively scheduling follow up visits. p53 is a tumor suppressor gene that expresses a protein that involved in both cell-cycle arrests after dna damage and apoptosis. presence of mutated p53 protein in tumors has been rel...

conclusions prognosis of this type of tumor, apart from its size and differentiation level, depends on infiltration in tumor-surrounding tissue, perineural and perivascular spread. therefore, it is always necessary to analyze the removed skin especially on margins. introduction squamous cell carcinoma is the most common type of lip and oral cavity cancers. in majority of cases it follows quite ...

squamous cell carcinoma (scc) of the buccal mucosa accounts for 23% to 37% of all intraoral cancers, the prognosis is generally poor. we reported a case of local invasion of buccal squamous cell carcinoma. a 32-year-old man referred to the clinic with a chief complaint of swelling in the right cheek region that initiated from 6 months ago and rapidly grow from one month ago. history of the pati...

patients. in this disease the risk of many malignancies is increased, of which the most important is non- hodgkin lymphoma of the small intestine. other malignancies include adenocarcinoma of the small intestine and squamous cell carcinoma of the esophagus. to the best of our knowledge, thus far only one case of celiac disease associated with hypopharyngeal squamous cell carcinoma has been repo...
