Granuloma inguinale is a bacterial disease caused by Klebsiella granulomatis characterized by genital ulcers. It is endemic in many less-developed regions. It is also known as donovanosis, granuloma genitoinguinale, granuloma inguinale tropicum, granuloma venereum, granuloma venereum genitoinguinale, lupoid form of groin ulceration, serpiginous ulceration of the groin, ulcerating granuloma of the pudendum, and ulcerating sclerosing granuloma. Oral manifestations are also notably seen. The lesions of oral cavity are usually secondary to active genital lesions.
Lupus vulgaris are painful cutaneous tuberculosis skin lesions with nodular appearance, most often on the face around the nose, eyelids, lips, cheeks, ears and neck. It is the most common Mycobacterium tuberculosis skin infection. The lesions may ultimately develop into disfiguring skin ulcers if left untreated.
Necrobiosis lipoidica is a necrotising skin condition that usually occurs in patients with diabetes mellitus but can also be associated with rheumatoid arthritis. In the former case it may be called necrobiosis lipoidica diabeticorum (NLD). NLD occurs in approximately 0.3% of the diabetic population, with the majority of sufferers being women.
Pyogenic granuloma or pyogenic fibroma 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. It is often found to involve the gums, the skin and nasal septum, and has also been found far from the head such as in the thigh.
A lick granuloma, also known as acral lick dermatitis, is a skin disorder found most commonly in dogs, but also in cats. In dogs, it results typically from the dog's urge to lick the lower portion of one of their legs.
Granuloma annulare is a fairly rare, chronic skin condition which presents as reddish bumps on the skin arranged in a circle or ring. It can initially occur at any age and is four times more common in females.
Erythema annulare centrifugum (EAC), is a descriptive term for a class of skin lesion presenting redness (erythema) in a ring form (anulare) that spreads from a center (centrifugum). It was first described by Darier in 1916. Many different terms have been used to classify these types of lesions and it is still controversial on what exactly defines EAC. Some of the types include annular erythema, erythema perstans, erythema gyratum perstans, erythema gyratum repens, darier erythema and erythema figuratum perstans.
Eosinophilic granuloma is a form of Langerhans cell histiocytosis. It is a condition of both human and veterinary pathology.
Aquarium granuloma is a skin condition caused by Mycobacterium marinum, characterized by a skin lesion that presents roughly three weeks after exposure.
Majocchi's granuloma is a skin condition characterized by deep, pustular plaques, and is a form of tinea corporis. It is a localized form of fungal folliculitis. Lesions often have a pink and scaly central component with pustules or folliculocentric papules at the periphery. The name comes from Professor Domenico Majocchi, who discovered the disorder in 1883. Majocchi was a professor of dermatology at the University of Parma and later the University of Bologna. The most common dermatophyte is called Trichophyton rubrum.
Localized granuloma annulare is a skin condition of unknown cause, tending to affect children and young to middle-aged adults, usually appearing on the lateral or dorsal surfaces of the fingers or hands, elbows, dorsal feet, and ankles.
Generalized granuloma annulare is a skin condition of unknown cause, tending to affect women in the fifth and sixth decades, presenting as a diffuse but symmetrical, papular or annular eruption of more than ten skin lesions, and often hundreds.
Patch-type granuloma annulare is a skin condition of unknown cause, more commonly affecting women between 30 and 70 years of age, characterized by flat or slightly palpable erythematous or red-brown skin lesions.
Perforating granuloma annulare is a skin condition of unknown cause, usually appearing on the dorsal hands, presenting as papules with a central keratotic core.
Granuloma annulare in HIV disease is a skin condition characterized typically by papular and generalized skin lesions.
Annular elastolytic giant-cell granuloma is a cutaneous condition characterized histologically by a dermal infiltrate of macrophages.
Actinic granuloma is a cutaneous condition characterized histologically by a dermal infiltrate of macrophages.
Granuloma multiforme is a cutaneous condition most commonly seen in central Africa, and rarely elsewhere, characterized by skin lesions that are on the upper trunk and arms in sun-exposed areas. It may be confused with tuberculoid leprosy, with which it has clinical similarities. The condition was first noted by Gosset in the 1940s, but it was not until 1964 that Leiker coined the term to describe "a disease resembling leprosy" in his study in Nigeria.
Eosinophilic ulcer of the oral mucosa is a condition characterized by an ulcer with an indurated and elevated border. The lesion might be tender, fast-growing and the patient often not be aware of any trauma in the area.
Weathering nodules of ear is a cutaneous condition seen on the helices of the ears of Caucasian men who have a history of significant cumulative sun exposure.
