A pyogenic granuloma or lobular capillary hemangioma [3] is a vascular tumor that occurs on both mucosa and skin, and appears as an overgrowth of tissue due to irritation, physical trauma, or hormonal factors. [4] [5] It is often found to involve the gums, skin, or nasal septum, and has also been found far from the head, such as in the thigh. [6]
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 ...
Granuloma; Picture of a granuloma (without necrosis) as seen through a microscope on a glass slide: The tissue on the slide is stained with two standard dyes (hematoxylin: blue, eosin: pink) to make it visible. The granuloma in this picture was found in a lymph node of a patient with a Mycobacterium avium infection. Specialty: Pathology
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.
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).
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.
Differential diagnosis includes vascular malformation, angioma, pyogenic granuloma, angiosarcoma, epithelioid hemangioendothelioma, Kaposi’s sarcoma, and other more rare vascular tumors. Three forms of intravascular papillary endothelial hyperplasia exist: the primary or pure form, the secondary or mixed form, and the extravascular form.
Involvement of the ears, nose, and throat is more common in granulomatosis with polyangiitis than in the similar condition microscopic polyangiitis. [7] If the person has signs of kidney involvement or cutaneous vasculitis, a biopsy is obtained from the kidneys. Rarely, a thoracoscopic lung biopsy is required.
