Tinea nigra. Tinea nigra, also known as superficial phaeohyphomycosis and Tinea nigra palmaris et plantaris, [2] is a superficial fungal infection, a type of phaeohyphomycosis rather than a tinea, that causes usually a single 1–5 cm dark brown-black, non-scaly, flat, painless patch on the palms of the hands and the soles of the feet of ...
Dermatophytosis. Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin [2] (a dermatomycosis), that may affect skin, hair, and nails. [1] Typically it results in a red, itchy, scaly, circular rash. [1] Hair loss may occur in the area affected. [1] Symptoms begin four to fourteen days after exposure. [1]
Chromoblastomycosis. Chromoblastomycosis is a long-term fungal infection of the skin [2] and subcutaneous tissue (a chronic subcutaneous mycosis). [3] It can be caused by many different types of fungi which become implanted under the skin, often by thorns or splinters. [4] Chromoblastomycosis spreads very slowly. [citation needed]
Tinea is often called "ringworm" because the rash is circular, with a ring-like appearance. It is sometimes equated with dermatophytosis, and, while most conditions identified as "tinea" are members of the imperfect fungi that make up the dermatophytes, conditions such as tinea nigra and tinea versicolor are not caused by dermatophytes.
Dermatophyte (from Greek δέρμα derma "skin" (GEN δέρματοςdermatos) and φυτόνphyton "plant") [ 1 ] is a common label for a group of fungus of Arthrodermataceae that commonly causes skin disease in animals and humans. [ 2 ] Traditionally, these anamorphic (asexual or imperfect fungi) mold genera are: Microsporum, Epidermophyton ...
Atopy is a hereditary [ 3 ] and chronic (lifelong) allergic skin disease. Signs usually begin between 6 months and 3 years of age, with some breeds of dog, such as the golden retriever, showing signs at an earlier age. Dogs with atopic dermatitis are itchy, especially around the eyes, muzzle, ears and feet.
Tinea corporis. This patient presented with ringworm on the arm, or tinea corporis due to Trichophyton mentagrophytes. Tinea corporis is a fungal infection of the body, similar to other forms of tinea. Specifically, it is a type of dermatophytosis (or ringworm) that appears on the arms and legs, especially on glabrous skin; however, it may ...
Hence, animals, cats and dogs are believed to be the population hosts of this fungus, while humans are occasional hosts, in which the fungus can induce secondary infections. [4] Microsporum canis has been identified as a causal agent of a ringworm infection in pets, tinea capitis and tinea corporis in humans, children in particular. [2] [3] [5 ...
