Osteoma represents the most common benign neoplasm of the nose and paranasal sinuses.
2.
Among this heterogeneous group, benign neoplasms predominate, particularly those with mucinous lining.
3.
Some of the small polyps in the field defect shown in the photo of the opened colon segment may be relatively benign neoplasms.
4.
TGF beta can act as a tumor suppressor in the premalignant stage of the benign neoplasm by inhibiting its growth and inducing apoptosis.
5.
Benign neoplasms are typically but not always composed of cells which bear a strong resemblance to a normal cell type in their organ of origin.
6.
The World Health Organization ( WHO ) classifies neoplasms into four main groups : benign neoplasms, in situ neoplasms, malignant neoplasms, and neoplasms of uncertain or unknown behavior.
7.
Since a cementoblastoma is a benign neoplasm, it grossly forms a mass of cementum-like tissue as an irregular or round mass attached to the roots of a tooth, usually the permanent mandibular first molar.
8.
Progression of EIN to carcinoma, effectively a conversion from a benign neoplasm to a malignant neoplasm, is accomplished through acquisition of additional mutations and accompanied by a change in behavior characterized by the ability to invade local tissues and metastasize to regional and distant sites.
9.
A "'glomus tumor "'( also known as a " solitary glomus tumor, " or "'glomangioma "') is a rare benign neoplasm arising from the glomus body and mainly found under the nail, on the fingertip or in the foot.
10.
Within these new patches ( sub-clones ), the process may have been repeated multiple times, indicated by the still smaller patches within the four secondary patches ( with still different colors in the diagram ) which clonally expanded, until a stem cell arose that generated either small polyps ( which may be benign neoplasms ) or else a malignant neoplasm ( cancer ).
