L66.10
Lichen planopilaris, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
Lichen planopilaris is a rare inflammatory scalp condition that leads to hair loss. It primarily affects adults and is considered a form of lichen planus that involves the hair follicles. This condition often results in scarring hair loss, which can be distressing for those affected. The exact cause of lichen planopilaris remains unclear, but immune system factors are believed to play a key role. Recognizing its symptoms and seeking appropriate diagnosis can help manage the condition effectively.
Causes & Symptoms
Clinical Causes: Autoimmune response, where the body's immune system mistakenly attacks hair follicle cells Genetic predisposition or family history of autoimmune or inflammatory skin conditions Triggers such as stress, certain medications, or skin injuries Possible links to other autoimmune disorders like lupus or psoriasis Environmental factors or allergens that may provoke immune reactions
Key Symptoms: Progressive hair loss, often starting at the temples or crown Itching, burning, or soreness on the scalp Redness and inflammation around hair follicles Scalp scalp skin may show visible scaling or patches of scarring Excessive shedding of hair that does not regrow in affected areas Presence of perifollicular erythema (redness around hair follicles)
Diagnostic & Treatment
Diagnosis Path: Medical history review and physical examination of the scalp Scalp biopsy to confirm inflammation and scarring characteristic of lichen planopilaris Dermoscopy (dermatoscopy) to examine scalp skin and hair follicles in detail Rule out other causes of hair loss such as alopecia areata or fungal infections
Treatment Protocols: Topical corticosteroids to reduce scalp inflammation Oral medications such as corticosteroids or immunosuppressants for severe cases Antimalarial drugs like hydroxychloroquine that may help modulate immune response Injections of corticosteroids directly into affected areas to decrease localized inflammation Use of gentle hair care practices to minimize scalp irritation Phototherapy or laser treatments might be considered in some cases Monitoring for progression and managing associated symptoms
