“…[2] One case due to T. ovoides reported by Shivprakash et al, was in a Sikh male in whom tying up of wet hair and increased humidity due to regular use of a turban may have been contributing factors. [10] With our report of T. mucoides, it appears that diverse species of Trichosporon may be implicated in causing white piedra. Antifungal drug susceptibilities may vary with species.…”

White piedra of scalp hair is considered a rare entity. We report three cases of this disorder all of whom presented with nodules on the hair. Potassium hydroxide preparations of the hair revealed clustered arthrospores and mature, easily detachable nodules. Cultures grew Trichosporon inkin in 2 patients and Trichosporon mucoides in one patient. Both these fungi are unusual causes of white piedra.

“…The condition called white piedra is the most common superficial infection in which white nodules are formed due to the aggregation of conidia around each hair shaft. The fungi remain in contact with the hair cuticle, without invading either the hair medulla, scalp or skin [36,43].…”

Fungal diseases have emerged as an important cause of morbidity and mortality, especially among immunocompromised patients. Pathogenic fungi have evolved an array of virulence factors to survive within the host and to outwit immune defenses. Fungi may cause a wide range of diseases in humans that range in extent from superficial to disseminated infections. Generally, the site of infections classifies the type of fungal disease, which can be divided into superficial, cutaneous, subcutaneous and systemic. In addition, the fungal virulence factors determine whether the infection will become established in the host. A primary pathogen may infect an immunologically normal host, whereas, an opportunistic pathogen requires some compromise of the host immune defenses in order for the infection to become established. This article covers the main fungi that are responsible for the increase of the fungal infections.Keywords: Fungal infections; Virulence; Yeast; Opportunistic infections; Endemic mycosis Fungal InfectionsFungal diseases have changed constantly in the last years. The virulence of these microorganisms has been adapted according to the human host, promoting a range of clinical manifestation. Several are the ways by which fungi promote a disease depending on human body part involved by the microorganism and the immunologic system of the host [1].In this review, we discuss the main fungal pathogens responsible for causing several diseases, highlighting on their virulence associate to clinical manifestation and the difficulty to accomplish the treatment. Superficial and cutaneous fungal diseasesSuperficial and cutaneous fungal infections are very common and occur worldwide affecting millions of people, especially immunocompromised patients. The most common types of these infections are dermatophytosis (tinea or ringworm), pityriasis versicolor (formerly tinea versicolor) and candidiasis (moniliasis). These occur by fungal invasion into the skin, keratinized tissues and mucous membranes [2]. Trichosporon and Fusarium species also cause superficial fungal infection, but also may be considered an invasive pathogen that may cause a systemic infection [3,4].Dermatophytosis: Dermatophytes are fungi that invade keratinized structures of humans and animals producing a condition called dermatophytosis or, more commonly, tinea [5,6]. These fungi belong to three main genera Trichophyton, Microsporum and Epidermophyton, of these T. rubrum is the most prevalent species worldwide [7,8]. The mechanisms of pathogenicity of these fungi are not yet well understood. There are several studies focusing on keratinolytic proteases (keratinases) produced by dermatophytes, but it is not known how these fungi regulate the use of these proteases to obtain nutrients from the stratum corneum substrate they invade, and whether there are additional roles of these proteins in adhesion and immunomodulation [9].To establish the infection, the contact of arthroconidia or hyphal fragmens with the host skin is essential. The fungi express spe...

“…The clinical appearance of WP is characterized by concretions or soft, whitish nodules on hair shaft. WP can be found in a variety of hairy areas including the scalp, beard, moustache, genitals, axilla, and even eyebrows and eyelashes [15]. The scalp lesions of white piedra are usually asymptomatic and can be misdiagnosed as pediculosis.…”

The highlight of this chapter is the description of the clinical manifestation and its pathogen and the host tissue damage observed under the transmission electron microscopy, which helps the clinician understand the pathogen's ultrastructure, the change of host sub-cell structure, and helps the laboratory workers understand the pathogen-induced human skin lesions' clinical characteristics, to establish a two-way learning exchange database with vivid images.
