Dermatitis papillaris capillitii (DPC) is a rare and benign scalp condition characterized by small, white, papillomatous (wart-like) lesions on the scalp. The exact cause of DPC is not well understood, but it is thought to be related to a combination of genetic and environmental factors. Dermatitis papillaris capillitii (DPC) is a rare form of scalp inflammation that results in the formation of small, firm, red papules (bumps) that may be itchy or painful. The exact cause of DPC is not known, but it is thought to be an immune-mediated disorder. It is often confused with scalp psoriasis. DPC is treated with topical corticosteroids and/or topical calcineurin inhibitors. In resistant cases, systemic immunosuppressant therapy may be considered.
Symptoms of DPC include:
- Small, white, wart-like lesions on the scalp
- Itching or burning sensation
- Scalp flaking or scaling
- Hair loss (in some cases)
DPC is typically diagnosed based on a physical examination of the scalp and the characteristic appearance of the lesions. A biopsy may be taken to rule out other conditions.
Treatment of DPC is typically not necessary as the condition is benign and usually resolves on its own. However, in some cases, treatment may be recommended to relieve symptoms and improve the appearance of the scalp involves addressing the underlying cause of the condition and managing symptoms. Treatment options may include:
- Topical medications: Steroid creams, lotions, or ointments may be prescribed to reduce inflammation and itching. Antifungal or antibacterial creams may also be used if an infection is present.
- Oral medications: If the condition is severe or does not respond to topical treatment, oral medications such as antibiotics, antihistamines, or corticosteroids may be prescribed.
- Phototherapy: Ultraviolet light therapy may be used to treat DPC in some cases.
- Hair care: Avoiding tight hairstyles, using mild shampoos, and avoiding harsh hair products may help to reduce symptoms and prevent further damage to the hair shafts.
- Lifestyle changes: Reducing stress and avoiding triggers such as certain foods or chemicals may also be helpful in managing DPC.
It is important to consult with a dermatologist for an accurate diagnosis and personalized treatment plan.
- Topical medications: Topical corticosteroids or calcipotriene may be used to reduce inflammation and itching.
- Cryotherapy: The use of liquid nitrogen to freeze and destroy the affected skin.
- Surgery: In some cases, surgical removal of the lesions may be recommended.
It is important to see a dermatologist for proper diagnosis and treatment, if needed.
