Tinea versicolor (also pityriasis versicolor) is a condition characterized by a skin eruption on the trunk and proximal extremities. [1] The majority of tinea versicolor is caused by the fungus Malassezia globosa , although Malassezia furfur is responsible for a small number of cases.
[3] [6] Superficial fungal infections include common tinea of the skin, such as tinea of the body, groin, hands, feet and beard, and yeast infections such as pityriasis versicolor. [7] Subcutaneous types include eumycetoma and chromoblastomycosis, which generally affect tissues in and beneath the skin.
In occasional opportunistic infections of the trunk and other locations on humans, some species of Malassezia can cause hypopigmentation or hyperpigmentation. Allergy tests for these fungi are available. The skin rash of tinea versicolor (pityriasis versicolor) is also caused by an infection of this fungus. [10]
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.
Treatment requires both systemic oral treatment with most of the same drugs used in humans—terbinafine, fluconazole, or itraconazole—as well as a topical "dip" therapy. [ 28 ] Because of the usually longer hair shafts in pets compared to those of humans, the area of infection and possibly all of the longer hair of the pet must be clipped to ...
The treatment of non-systemic Candida infections of the vagina ("yeast infections"), throat, and mouth. Certain systemic Candida infections in people with healthy immune systems, including infections of the bloodstream, kidney, or joints. Other antifungals are usually preferred when the infection is in the heart or central nervous system, and ...
Often no specific cause for the eruptions is found. However, it is sometimes linked to underlying diseases and conditions such as: Food (including blue cheese or tomatoes). Contact Dermatitis (i.e. cleaning agents, fabric softeners, etc.) Fungal, Bacterial and Viral infections such as sinusitis, tuberculosis, candidiasis or tinea.
Most dermatomycoses are mild and resolve without treatment, but many are treated clinically with topical antifungal medicines. Oral antifungals are also an option for treatment. [1] One of the most frequent forms is dermatophytosis (ringworm, tinea) which includes tinea pedis, also known as athlete's foot. Another example is cutaneous ...
