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.
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).
Numerous treatment methods have been described for pyogenic granuloma. Lesions involving the reticular dermis, may be out of the reach of pulsed-dye laser, cautery or shave excision and therefore have a recurrence rate of 43.5%. [6] Definitive management requires full-thickness skin excision. Other options are curettage or laser therapy ...
Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps. Its histological appearance is characterized by proliferation of fibroblasts and thin-walled, delicate capillaries ( angiogenesis ), and infiltrated inflammatory cells in a loose extracellular matrix.
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.
Epulis fissuratum is the third most common reactive lesion that occurs in the mouth, after peripheral giant cell granuloma and pyogenic granuloma. [ 10 ] References
Clinically, there is no way to differentiate peripheral odontogenic fibroma from other common fibrous gingival lesions, [4] including peripheral giant cell lesion, pyogenic granuloma, inflammatory fibrous hyperplasia, and peripheral ossifying fibroma. [5] Rarely have diffuse or multifocal lesions been reported.
Nodules in skin include dermatofibroma [5] and pyogenic granuloma. [6] Nodules may form on tendons and muscles in response to injury, [7] and are frequently found on vocal cords. [8] They may occur in organs such as the lung, [9] or thyroid, [10] or be a sign in other medical conditions such as rheumatoid arthritis. [11]
