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.
Actinic granuloma is distinguished histopathologically by multinucleated foreign body giant cells that phagocytize the degenerated elastic fibers, a process known as elastophagocytosis. At the solar elastosis level, there is no necrobiosis , such as facial necrobiosis lipoidica , or mucinosis , such as GA or sarcoid-like granuloma in the dermis.
The first known name for this condition was "serpiginous ulcer", which dates to 1882. [11] [12] The proper clinical designation for donovanosis is "granuloma inguinale". [5] A granuloma is a nodular type of inflammatory reaction, and inguinale refers to the inguinal region, which is commonly involved in this infection. The disease is commonly ...
Granuloma annulare (GA) is a rare, [1] sometimes chronic skin condition which presents as reddish bumps on the skin arranged in a circle or ring. [2] It can initially occur at any age, though two-thirds of patients are under 30 years old, and it is seen most often in children and young adults. Females are two times as likely to have it as males ...
Eosinophilic ulcer of the oral mucosa (eosinophilic ulcer of the tongue, Riga–Fede disease, traumatic eosinophilic granuloma) Eosinophilic ulcer of the oral mucosa; Eosinophilic vasculitis; Erythema toxicum neonatorum (erythema toxicum, toxic erythema of the newborn) Granuloma faciale; Hypereosinophilia; Hypereosinophilic syndrome
This contagious skin rash is caused by streptococcus and staphylococcus bacteria that enter the body through compromised skin. Other symptoms to note: Initially, red blisters form at the infection ...
Generalized granuloma annulare is a chronic granulomatous dermatosis that typically affects young adults' distal extremities and manifests as annular grouped papules. [2] On the trunk and extremities, numerous flesh-colored papules arranged in an annular pattern are the hallmark of generalized granuloma annulare. These lesions are frequently ...
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]
