ICD-10: B36.2

White piedra, classified under ICD-10 code B36.2, is a type of superficial mycosis characterized by the presence of white, soft, and nodular growths on hair shafts. This condition is primarily caused by fungal infections, specifically by the yeast-like fungus Trichosporon. Below is a detailed overview of the clinical description, symptoms, diagnosis, and treatment options for white piedra.

Clinical Description

Etiology

White piedra is caused by the Trichosporon species, which are part of the normal flora of the skin and mucous membranes. The condition typically arises when these fungi proliferate excessively, often due to factors such as poor hygiene, immunosuppression, or environmental conditions that favor fungal growth.

Symptoms

The hallmark of white piedra is the appearance of soft, white to light brown nodules on the hair shafts. These nodules can vary in size and may be easily removed from the hair. The condition is most commonly found on the scalp, but it can also affect other areas with hair, such as the beard, axillae, and pubic region. Unlike other forms of hair infections, white piedra is generally not associated with significant inflammation or discomfort.

Risk Factors

Several factors can increase the risk of developing white piedra, including:
- Poor personal hygiene
- Warm and humid climates
- Immunocompromised states (e.g., HIV infection, diabetes)
- Use of certain medications that suppress the immune system

Diagnosis

Clinical Examination

Diagnosis of white piedra is primarily clinical, based on the characteristic appearance of the nodules on the hair. A thorough examination by a healthcare professional is essential to differentiate it from other hair shaft disorders, such as black piedra or other dermatological conditions.

Laboratory Tests

In some cases, a microscopic examination of the hair may be performed to identify the presence of Trichosporon species. Fungal cultures can also be conducted to confirm the diagnosis and determine the specific type of fungus involved.

Treatment

Antifungal Therapy

The primary treatment for white piedra involves the use of topical antifungal agents. Commonly prescribed medications include:
- Ketoconazole: An antifungal cream that can be applied directly to the affected areas.
- Clotrimazole: Another topical antifungal that may be effective in treating the condition.

Hygiene Measures

Improving personal hygiene and maintaining clean, dry hair can help prevent recurrence. Regular washing of hair with antifungal shampoos may also be recommended.

Prognosis

With appropriate treatment, white piedra is generally considered a benign condition, and most patients respond well to antifungal therapy. However, recurrence can occur, particularly if predisposing factors are not addressed.

Conclusion

White piedra, represented by ICD-10 code B36.2, is a superficial fungal infection that primarily affects hair shafts, leading to the formation of soft, white nodules. While it is not typically associated with severe symptoms, proper diagnosis and treatment are essential to manage the condition effectively.
