A fungal infection affecting hair

White Piedra

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

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

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

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

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

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