Exophiala dermatitidis forms slow growing, brown or black colonies. As is common amongst black yeasts, E. dermatitidis is an anamorphic fungus with multiple conidial forms. This morphological plasticity has complicated taxonomic determination based solely on physical appearance.
Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin (a dermatomycosis), that may affect skin, hair, and nails. Typically it results in a red, itchy, scaly, circular rash. [1]
Tinea faciei is a fungal infection of the skin of the face. It generally appears as a photosensitive painless red rash with small bumps and a raised edge appearing to grow outwards, usually over eyebrows or one side of the face. It may feel wet or have some crusting, and overlying hairs may fall out easily. There may be a mild itch.
Mucormycosis, also known as black fungus, is a serious fungal infection that comes under fulminant fungal sinusitis, usually in people who are immunocompromised. It is curable only when diagnosed early. Symptoms depend on where in the body the infection occurs.
Tinea versicolor (also pityriasis versicolor) is a condition characterized by a skin eruption on the trunk and proximal extremities. The majority of tinea versicolor is caused by the fungus Malassezia globosa, although Malassezia furfur is responsible for a small number of cases.
Malassezia furfur. Malassezia furfur (formerly known as Pityrosporum ovale) is a species of yeast (a type of fungus) that is naturally found on the skin surfaces of humans and some other mammals. It is associated with a variety of dermatological conditions caused by fungal infections, notably seborrhoeic dermatitis and tinea versicolor.
Epidermodysplasia verruciformis. Epidermodysplasia verruciformis ( EV) is a skin condition characterised by warty skin lesions. [1] It results from an abnormal susceptibility to HPV infection (HPV) and is associated with a high lifetime risk of squamous cell carcinomas in skin. [1] It generally presents with scaly spots and small bumps ...
Tinea nigra, also known as superficial phaeohyphomycosis and Tinea nigra palmaris et plantaris, 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 healthy people.
The rash may appear reddish, tan, or brown, with flaking, rippling, peeling, iridescence, or cracking skin. If the person is hairy, hair follicles can become inflamed resulting in some bumps (papules, nodules and pustules) within the plaque. The plaque may reach the scrotum in men and the labia majora and mons pubis in women.
Vitiligo ( / ˌvɪtɪˈlaɪɡoʊ /) is a chronic autoimmune disorder that causes patches of skin to lose pigment or color. [1] The cause of vitiligo is unknown, but it may be related to immune system changes, genetic factors, stress, or sun exposure. [5] [6] Treatment options include topical medications, light therapy, surgery and cosmetics. [6]
