results 81 females aged 24 to 67 years (mean 43 ± 9.2) met the inclusion criteria and had adequate samples for histopathologic study. 28 (34%) patients had ml, 46 (56.8%) patients had nml and 7 (8.6%) had both ml and nml. rate of normal result, epithelial hyperplasia, fibrocystic changes, fibroadenoma, papilloma, atypical hyperplasia, mixed fibrocystic changes and atypical hyperplasia, ductal c...

Sequential morphological changes occurring after brief carcinogen exposures of heterotopic tracheal transplants in rats were semiquantitatively studied. Tracheas were exposed to 7,12-dimethylbenz(a)anthracene for 1, 2, or 4 weeks, during which time means of 138, 152, and 160 microgram 7,12-dimethylbenz(a)anthracene, respectively, were delivered. The first two types of exposures resulted only in...

Figure: benign, well-limited hepatocellular tumor with major haemorrhagic foci and telangiectasia on histology. Beside Focal Nodular Hyperplasia and hepatocellular adenomas, the most frequent benign hepatocellular lesion in the liver, a variant, initially called «telangiectatic focal nodular hyperplasia» now claimed as “telangiectatic adenoma” has been described recently. Initially observed in ...

Focal epithelial hyperplasia (FEH) is a human papillomavirus (HPV)-induced alteration of the oral mucosa that presents with a clinically distinct appearance. While other HPV-infected lesions such as squamous papilloma, verruca vulgaris, and condyloma acuminatum involve the skin, oral mucosa, and genital mucosa, FEH occurs only in the oral mucosa. The affected oral mucosa exhibits multiple papul...

background: the aim of this study was to quantify the number of mast cells in focal reactive hyperplastic lesions of the oral cavity and to compare these two number of mast cells in normal gingival tissues and to correlate their presence with the state of connective tissue changes in reactive lesions and probably suggest a role for mast cells in these lesions. materials and methods: patient rec...

Aim: Mammography and ultrasonography are helpful diagnostic methods for the detection of asymptomatic lesions prior to reduction mammoplasty operations. Preoperative radiological evaluation does not give accurate results all time. Consequently, preoperative radilological and postoperative histopathologic evaluation were used together in order to diagnose the premalignant and silent cancer foci....

Prostatic intra-epithelial neoplasia (PIN) is considered a precursor of invasive carcinoma, characterized by proliferation and anaplasia of cells lining prostatic ducts and acini. In this study, we applied the PIN grading system on one-hundred cases of prostatic carcinoma and one-hundred cases of benign prostatic hyperplasia, then compared the results. 74% of prostatic carcinoma and 51 % of...

Focal nodular hyperplasia is the second most common benign hepatic tumor. Unlike adenoma as well as the malignant neoplasms, focal nodular hyperplasia can often be managed successfully without surgery. Use of liver-specific contrast-enhanced magnetic resonance imaging allows clinicians to confirm the diagnosis noninvasively in some patients, allowing select patients to avoid surgery. We report ...
