Diagnosis: Lichen planopilaris
A 45-year-old woman presents with progressive hair loss over the past six months, accompanied by perifollicular erythema and scaling. Physical examination reveals scarring alopecia with follicular hyperkeratosis, and the patient expresses concern about the aesthetic impact of her condition.
A 45-year-old woman presents with a six-month history of progressive hair loss, primarily affecting the crown and frontal scalp. She reports associated symptoms of itching and tenderness in the affected areas. On examination, there is notable perifollicular erythema and scarring alopecia with follicular hyperkeratosis. Hair pull test reveals diminished hair density in the affected regions.Scarring alopecia: Loss of hair follicles with evidence of scarring.Perifollicular erythema: Redness surrounding hair follicles, indicating inflammation.Follicular hyperkeratosis: Keratin buildup around hair follicles, often seen in lichenoid conditions.Itching: Common symptom associated with inflammatory scalp conditions.Hair pull test: Positive in areas of active inflammation, suggesting ongoing hair loss.
The patient reports that her hair loss began approximately six months ago, with no identifiable triggers such as recent illness or stress. She has no significant past medical history and denies a family history of autoimmune conditions. She has not tried any treatments for her hair loss, but has used topical corticosteroids for other dermatological issues in the past with moderate success. The patient is otherwise healthy and does not take any regular medications.Onset: Symptoms began six months prior with no identifiable triggers.Prior treatments: No specific treatments attempted for hair loss; has used topical corticosteroids for other skin conditions.Family history: No known family history of autoimmune diseases or similar skin conditions.Social history: Non-smoker, moderate alcohol use, works as a teacher.Past medical history: Generally healthy, no significant medical issues reported.
Acute / First-Line ManagementIntralesional corticosteroids: Triamcinolone acetonide 5-10 mg/mL, injected every 4-6 weeks into affected areas.Topical corticosteroids: Clobetasol propionate ointment applied twice daily to affected scalp areas.Workup and Diagnostic ConfirmationScalp biopsy: Punch biopsy to assess for lichenoid tissue changes and confirm diagnosis.Laboratory tests: Consider thyroid function tests and antinuclear antibody (ANA) panel if autoimmune etiology is suspected.Long-Term ManagementOral corticosteroids: Consider prednisone 0.5-1 mg/kg/day for severe cases, tapering as improvement is noted.Minoxidil: Topical minoxidil 5% may be beneficial as an adjunct therapy to stimulate hair regrowth.Regular follow-up: Assess treatment efficacy and adjust management strategies every 3-6 months.
Alopecia areata: Presents with non-scarring hair loss, often in patches; hair pull test may reveal easily extractable hair.Folliculitis decalvans: Characterized by pustular lesions and scarring alopecia; biopsy shows neutrophilic inflammation.Discoid lupus erythematosus: Scarring alopecia with erythematous plaques; often associated with systemic lupus erythematosus.Frontal fibrosing alopecia: Typically affects postmenopausal women, characterized by a receding hairline and eyebrow loss.Central centrifugal cicatricial alopecia: Common in women of African descent, presents with scarring alopecia localized to the crown.Keratosis pilaris: Presents with follicular keratosis but lacks scarring; typically not associated with hair loss.Scarring alopecia due to trauma: History of physical trauma or traction can lead to scarring, unlike primary lichenoid processes.
High-Yield PearlsDiagnosis: Accurate diagnosis of scarring alopecia is critical to prevent irreversible hair loss.Biopsy: Scalp biopsy is essential for definitive diagnosis, particularly to differentiate from other forms of alopecia.Intralesional therapy: Intralesional corticosteroids are a first-line treatment option for inflammatory scarring alopecia.Minoxidil: Topical minoxidil can aid in hair regrowth and should be considered as an adjunct therapy.Regular follow-up: Continuous monitoring of treatment response is crucial, as management may need adjustment over time.Early intervention in scarring alopecia can significantly improve outcomes and prevent permanent hair loss.
