Linear Lichen Planopilaris of the Trunk: First Report of a Case

    TLDR Linear lichen planopilaris can affect the trunk, not just the face.
    The document reported the first case of linear lichen planopilaris (LPP) on the trunk, a rare variant of LPP that typically affects the face. A 34-year-old male presented with nonpruritic, erythematous, keratotic papules following Blaschko's lines on his trunk. Biopsy confirmed the diagnosis of LPP by revealing lichenoid and interface dermatitis involving the basilar epidermis and hair follicles, along with apoptotic keratinocytes. This case expanded the known distribution of linear LPP beyond the face.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      Men with hair loss might have lichen planopilaris (LPP), which can mimic androgenetic alopecia, leading to misdiagnosis and ineffective treatment with finasteride or dutasteride. Proper diagnosis, including biopsies, is crucial to distinguish between androgenetic alopecia and conditions like LPP.

      Excess sebum rich in cholesterol and triglycerides can lead to hair loss through inflammation, with treatments like Ciclopirox shampoo, Benzoyl Peroxide shampoo, and Clindamycin gel recommended for managing conditions like seborrheic dermatitis and folliculitis. Pioglitazone is suggested for Lichen Planopilaris, while Omega-3s and reducing processed foods may improve sebum quality, though genetic factors play a significant role.
