The name "pyogenic granuloma" is misleading, as it is neither pyogenic or a true granuloma. Rather, it is a capillary hemangioma of lobular subtype, which is why such a lesion is prone to bleeding. [5] It is also not truly pyogenic (pus-producing), as the cause is hormonal or traumatic and has no association with infection or pus production.
Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. [1] Granulation tissue typically grows from the base of a wound and is able to fill wounds of almost any size. Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps.
This type of epulis is neither pyogenic ("pus producing") nor a true granuloma, but it is a vascular lesion.About 75% of all pyogenic granulomas occur on the gingiva, [2] growing beneath the gingival margin, [8] although they may also occur elsewhere in the mouth or other parts of the body (where the term epulis is inappropriate).
Neoplasms of the nailbed may often present with paronychia, ingrown nail, onycholysis, pyogenic granuloma, nail-plate dystrophy, longitudinal erythronychia, bleeding, and discolorations. [ 1 ] : 792 There are various benign and malignant neoplasms that may occur in or overlying the nail matrix and in the nailbed, and symptoms may include pain ...
Instead, the three are associated with each other because they appear frequently on gingiva: pyogenic granuloma and peripheral giant cell granuloma. Some researchers believe peripheral ossifying fibromas to be related to pyogenic fibromas and, in some instances, are the result of a pyogenic granuloma which has undergone fibrosis and calcification.
They usually occur in the elderly population (mean age 65.1–66.6 in different studies) as small (<2 centimeters), solitary dome-shaped papules, plaques, or nodules, that are skin-colored, pink, red, white, or blue and range from smooth to wart-like, ulcerative, [4] or pyogenic granuloma-like lesions. [10]
The appearance may also be confused with pyogenic granuloma. [1] The excessive tissue is composed of cellular, inflamed fibrous connective tissue. The appearance of an epulis fissuratum microscopically is an overgrowth of cells from the fibrous connective tissue.
Pyogenic granuloma may occur elsewhere in the mouth such as the tongue and lips, but are not therefore epulides. Giant cell epulis, also known as peripheral giant cell granuloma, are like fibrous epulis and occur at the anterior interdental margin, the gum between the teeth at the front. They are more common in women.
