pregnancy tumor is a benign, hyperplastic lesion of the gingiva, considered to be reactive or traumatic rather than neoplastic in nature. the term pyogenic granuloma is a misnomer as it is not filled with pus or granulomatous tissue histologically. it is multi factorial in nature, which shows an exaggerated response to stimuli such as low grade or chronic irritation, trauma or hormonal variatio...

Eccrine syringofibroadenoma (ESFA) is a very rare benign tumour of intraepidermal part (acrosyringium) of eccrine sweat duct. Based on the evidence of known aetiological factors, two forms have been proposed: reactive ESFA and non-reactive ESFA. Rarely, non-reactive forms have been seen to be associated with ectodermal dysplasia. Reactive type has been considered as hyperplastic or hamartomatou...

Head and neck cancer develops in a multistep process and is associated with increasing frequencies of p53 alterations and with increasing genomic instability. To study the relationship of p53 alterations and genomic instability during head and neck tumorigenesis, we analyzed p53 protein expression and chromosome 9 and 17 polysomy in 48 squamous cell carcinomas of the head and neck and their adj...

BACKGROUND Granulomatosis with polyangiitis (GPA), formerly referred to as Wegener's granulomatosis, is a rare systemic disease of unknown etiology which can affect all areas of the body, including the oral cavity. The typical oral manifestations occur as nonspecific erosive/ulcerative lesions of the oral cavity or appear with hyperplastic gingivitis, a so called "strawberry gingivitis". CASE...

The gene responsible for neurofibromatosis type 1 (NF1) encodes a tumor suppressor that functions as a negative regulator of the Ras proto-oncogene. Individuals with germline mutations in NF1 are predisposed to the development of benign and malignant tumors of the peripheral and central nervous system (CNS). Children with this disease suffer a high incidence of optic gliomas, a benign but poten...

BACKGROUND During colonoscopy, correct assessment of polyps is important. Recognition of early carcinomas is needed for tailor-made treatment and avoidance of unnecessary complications. Moreover, accurate diagnosis of diminutive lesions could result in a safe resect and discard strategy. We assessed the accuracy of polyp assessment by general endoscopists without specific training or experience...

BACKGROUND Diagnosis of premalignant endometrial lesions is a major challenge to pathologists. The D-score system is more reproducible than the WHO scheme, however it is not widely available, this study attest a simple custom-made workstation for estimation of the "D-score". MATERIAL AND METHODS Fifteen endometriam with low grade hyperplasia, fifteen proliferative and eight secretory phase en...

BACKGROUND This study aimed to evaluate upper gastrointestinal polyps detected during esophago- gastroduodenoscopy tests. MATERIALS AND METHODS We conducted a retrospective analysis on data regarding 55,987 upper gastrointestinal endoscopy tests performed at the endoscopy unit of Istanbul Education and Research Hospital between January 2006 and June 2012. RESULTS A total of 66 upper gastroi...
