Background & Objective: Chronic non healing ulcers or scar undergoing malignant transformation is a rare phenomenon with an estimated incidence of 2%. Though, numerous predisposing factors have been identified, still it is rarely diagnosed and commonly mistaken for a benign condition. The objective of this study was to verify the efficacy of the Fine Needle Aspiration Cytology/ Scrape cytology ...

Erlotinib, bevacizumab, and pemetrexed improved survival of metastatic non-small cell lung cancer (mNSCLC) in clinical trials, but their benefits are restricted to non-squamous histology. We studied recent survival trends in mNSCLC subpopulations defined by histology and associated clinical factors correlating with adenocarcinoma or endothelial growth factor receptor mutations. Using the Survei...

introduction: sentinel node mapping has been used for laryngeal carcinoma in several studies, with excellent results thus far.in the current study, we report our preliminary results on sentinel node mapping in laryngeal carcinoma using intra-operative peri-tumoral injection of a radiotracer.   materials and methods: patients with biopsy-proven squamous cell carcinoma of the larynx were included...

to evaluate the effect of adding neoadjuvant chemotherapy to surgery and radiation therapy for locally advanced resectable oral cavity squamous cell carcinoma, 24 patients with t3 or t4a oral cavity squamous cell carcinoma were randomly assigned to surgery alone or docetaxel, cisplatin, and 5-fu (tpf) induction chemotherapy followed by surgery. all patients were planned to receive chemoradiothe...

although the diagnostic category of atypical squamous cells of undetermined significance (ascus) has been known since 1988, its use and appropriate clinical follow up and management still remains controversial. this study was carried out to evaluate the diagnostic value of ascus, using cytohistologic correlation. a retrospective review of archival materials in our cytology laboratory files was ...

Four cases of conjunctival squamous carcinoma invading the cornea are presented. The surgical technique of excising the tumours from the cornea by lamellar keratectomy is described. Histology of the lesions showed well differentiated squamous carcinoma invading the superficial layers of the cornea only. Large invasive squamous cell carcinomas of the cornea result because of neglect of small par...

background and objective: the frequency and pattern of eye neoplasms differ in various geographic areas. our aim was to determine the distribution of patient age, gender, ocular tumor origin, location and histological type in our region. materials and methods: in this cross-sectional study, all of the 384 eye globe enucleation cases carried out during a 10-year period in farabi medical center i...

introduction: diagnosis, prediction and control of oral lesions is usually done classically based on clinical signs and histopathologic features. due to lack of timely diagnosis in all conventional methods or differential diagnosis, biopsy of patient is needed. therefore, the patient might be irritated. so, an intelligent method for quick and accurate diagnosis would be crucial. intelligent sys...
