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

    May 2006 in “ Journal of Cutaneous Medicine and Surgery ”
    Kristi Baker, Kevin Pehr
    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.

      A young female diagnosed with Lichen planopilaris (LPP) experienced years of misdiagnosis and ineffective treatments, including a hair transplant and other procedures. She is considering litigation due to the misdiagnosis and has learned that LPP is chronic, hair loss can be stopped with ongoing medication, but lost hair cannot regrow.
