A fungal infection affecting hair

White piedra is a superficial fungal infection of the hair shaft caused by fungi of the genus Trichosporon. It is characterized by the presence of soft, white nodules on the hair shafts of the scalp, beard, mustache, and other body hair.

Etiology[edit]

White piedra is primarily caused by the yeast-like fungi Trichosporon ovoides and Trichosporon inkin. These fungi are part of the normal flora of the human skin and can become pathogenic under certain conditions.

Clinical Presentation[edit]

Patients with white piedra typically present with:

White or light-colored nodules on the hair shaft
Nodules that are soft and easily detached
Possible hair breakage

The infection is usually asymptomatic, but some patients may experience mild itching.

Diagnosis[edit]

Diagnosis of white piedra is primarily clinical, based on the appearance of the nodules. However, confirmation can be achieved through:

Microscopic examination of the hair shaft
Culture of the fungi

Treatment[edit]

Treatment options for white piedra include:

Shaving or cutting the affected hair
Topical antifungal agents such as ketoconazole or clotrimazole
Oral antifungal medications in severe cases

Prevention[edit]

Preventive measures include maintaining good personal hygiene and avoiding sharing personal items such as combs and hats.

-'''White piedra''' is a superficial fungal infection of the hair shaft, caused by the yeast-like fungus ''[[Trichosporon]]''. The infection is characterized by the presence of soft, white-to-tan nodules along the hair shaft. These nodules are easily removable and are composed of yeast cells and arthroconidia that are tightly packed and surrounded by a cement substance.
