Granuloma annulare is a skin disease of unknown cause in which granulomas are found in the dermis of the skin, but it is not a true granuloma. Typically, a central zone of necrobiotic generation of collagen is seen, with surrounding inflammation and mucin deposition on pathology.
Pyogenic granuloma. A pyogenic granuloma, is a small benign vascular tumor that primarily involves the skin (88.2%) and mucous membranes. [6] Pyogenic granuloma appears as a red macule that grows rapidly, turns into a papule and eventually becomes pedunculated, being attached to a narrow stalk. [8]
Granulation tissue is composed of tissue matrix supporting a variety of cell types, [3] most of which can be associated with one of the following functions: formation of extracellular matrix;
It is believed that an augmented cell-mediated immune response to one or more undiscovered antigens is the cause of the granulomatous inflammation. [6] Environmental exposure may have a role in the etiology of sarcoidosis, as evidenced by the development of granulomas that resemble sarcoid granulomas after exposure to metals such beryllium ...
Mycosis fungoides, also known as Alibert-Bazin syndrome or granuloma fungoides, [1] is the most common form of cutaneous T-cell lymphoma. It generally affects the skin, but may progress internally over time. Symptoms include rash, tumors, skin lesions, and itchy skin. While the cause remains unclear, most cases are not hereditary.
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]
Skin blisters exemplify this pattern of inflammation. Ulcerative inflammation: Inflammation occurring near an epithelium can result in the necrotic loss of tissue from the surface, exposing lower layers. The subsequent excavation in the epithelium is known as an ulcer.
Poikiloderma vasculare atrophicans, or PVA, indicates that extra or altered skin pigmentation ("poikiloderma") [10] is occurring, associated with heightened visibity of capillaries ("vasculare", referring to telangiectasia) under the skin, related to thinning and wasting away ("atrophicans") of the skin and its tissue. Telangiectasia is an ...
