background patients presenting with a mass require tissue biopsy for histological diagnosis and treatment. fine needle aspiration (fna) is offered as an atraumatic, well tolerated, and inexpensive method for obtaining a biopsy from these lesions. objectives in this study we evaluated the accuracy of fna as an atraumatic method among patients with nonthyroidal masses for diagnosis of neoplastic ...

Association of lichen planus and cutaneous malignancies is rare. Reports of neoplastic changes are mostly related to buccal chronic erosive lichen planus. We report herein a 29-year-old man who developed squamous cell carcinoma on previous lesions of chronic hypertrophic lichen planus of lower legs. Careful follow up of patients with chronic lichen planus and biopsy sampling of uncommon lesions...

The development of the oral squamous cell carcinoma (OSCC) is a multistep process that requires the accumulation of multiple genetic alterations usually preceded by detectable mucosal changes, most often leukoplakias and erythroplakias. The clinical appearance of oral precancerous lesions and their degree of epithelium dysplasia suggests the malignization potential. Several techniques have been...

Surgical risks are traditionally derived from cancer operations, which may not be generalizable given differences in patient factors, use neoadjuvant chemotherapy radiation. By better understanding perioperative...

BACKGROUND Screening for colorectal cancer (CRC) has shown to reduce cancer-related mortality, however, acceptance and compliance to current programmes are poor. Developing new, more acceptable non-invasive tests for the detection of cancerous and precancerous colorectal lesions would not only allow preselection of individuals for colonoscopy, but may also prevent cancer by removal of precancer...
