Onychomycosis, also known as tinea unguium, [4] is a fungal infection of the nail. [2] Symptoms may include white or yellow nail discoloration, thickening of the nail, and separation of the nail from the nail bed. [2] Fingernails may be affected, but it is more common for toenails. [3] Complications may include cellulitis of the lower leg. [3]
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 ...
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]
Symptoms can range from mild to extreme—often described as extreme flu-like symptoms. Many symptoms may be associated with fungemia, including pain, acute confusion, chronic fatigue, and infections. Skin infections can include persistent or non-healing wounds and lesions, sweating, itching, and unusual discharge or drainage. [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.
Signs and symptoms range widely. [3] There is usually a rash with superficial infection. [2] Fungal infection within the skin or under the skin may present with a lump and skin changes. [3] Pneumonia-like symptoms or meningitis may occur with a deeper or systemic infection. [2] Fungi are everywhere, but only some cause disease. [13]
Topical antifungal treatment, such as the use of terbinafine, itraconazole, voriconazole, and ketoconazole, is often effective. [5] E. floccosum is one of the 2 species in the genus Epidermophyton. [6] [7] During the 20th century, this species was the fourth most common cause of dermatophytosis in North America. [8]
The diagnosis can be made on the clinical picture alone. However, a simple side-room investigation with a Wood's lamp is additionally useful in diagnosing erythrasma. [ 4 ] The ultraviolet light of a Wood's lamp causes the organism to fluoresce a characteristic coral red color, differentiating it from other skin conditions such as tinea ...
