The findings of Surgeon-performed Us-FNAC of solitary thyroid nodule shows 10 cases (10%) were inconclusive/Non-diagnostic, 60 cases (60%) Non-neoplastic (40 adenomatous/colloid goiters, 12 hyperplastic nodules, five Hashimoto thyroiditis, three colloid cyst) and 30 cases (30%) Neoplastic lesions (follicular neoplasm 22(73.4%), Hurthle cell adenoma 2 (6.6%), papillary carcinoma 6 (20.0%).
The first group is epithelial polyps, such as fundic gland polyps (FGP), hyperplastic polyps (HP), adenomatous polyps (AP), hamartomatous polyps and non-hamartomatous-polyposis syndromes.
Nonneoplastic duodenal epithelial polyps include Brunner gland hyperplastic nodule/polyps (also known as Brunner gland hyperplasia), Brunner gland hamartomas, Brunner gland cysts, ectopic gastric mucosa, pancreatic heterotopia, hyperplastic polyps, inflammatory polyps, and hamartomatous polyps.
In histological sections of all the varieties, the tissues of the vascular cylinder as well as various layers of hyperplastic tissue in the central zone of galls were composed of isodiametric parenchyma cells of approximately 50 [micro]m in diameter.
In our cohort, polyps were pathologically classified as "hyperplastic" in the majority of cases, even though they showed the abovementioned histological criteria of portal hypertensive polyps.
Reactive hyperplastic lesion is defined as an excessive proliferation of connective tissue in response to chronic irritation.
Figure 4 depicts the tumor's vascular invasion, and the adrenal gland's hyperplastic cortex.
Hyperplastic polyps, which are common in the colon and particularly in the rectum, were considered nonneoplastic lesions for several years [1-3].
(1,2) Serrated polyps are classified histologically into 3 subgroups: Hyperplastic polyps, sessile serrated adenomas, and traditional serrated adenomas.
The term chronic hyperplastic pulpitis is attributed to the development of granulation tissue, most of the times covered with epithelium and resulting from long-standing, low-grade irritation.
The diagnosis was hyperplastic and hypertrophied Bartholin's gland.
In hard tissue application, the laser is used for caries prevention, bleaching, restorative removal and curing, cavity preparation, dentinal hypersensitivity, growth modulation and for diagnostic purposes, whereas soft tissue application includes wound healing, removal of hyperplastic tissue to uncovering of impacted or partially erupted tooth, photodynamic therapy for malignancies, photo stimulation of herpetic lesion.
