Fibrosing Alopecia in a Pattern Distribution in Two Brothers with Pili Multigemini

    July 2015
    B. Kamoona, Dimitrina Serafimova, Valentina Broshtilova, ,
    TLDR Genetic factors might cause fibrosing alopecia linked to hair shaft abnormalities.
    The document described a case study of two brothers, aged 25 and 26, who experienced increased hair loss over two years. They were diagnosed with a rare hair shaft defect known as pili multigemini, where multiple hairs grow from a single follicle, and fibrosing alopecia in a pattern distribution, a subtype of lichen planopilaris characterized by inflammation and fibrosis leading to hair loss in typical male or female pattern areas. The study suggested that the pili multigemini defect might have influenced the development of fibrosing alopecia in these cases.

      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.

      in Research/Science  99 upvotes 10 months ago
      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.
