Malassezia (Pityrosporum) Folliculitis Occurring With Granuloma Annulare and Alopecia Areata

    October 1983 in “ Archives of Dermatology
    James M. Hanna
    TLDR A man had a unique case of three skin conditions happening together.
    A 35-year-old man presented with hair loss and a pruritic eruption on his back and chest, diagnosed as Malassezia folliculitis, granuloma annulare, and alopecia areata. This case was notable as it was the first reported instance of Malassezia folliculitis occurring alongside other dermatologic conditions. The American Society for Microbiology had recently updated the nomenclature, combining Pityrosporum ovale and P. orbiculare under Malassezia furfur. The patient's medical history was unremarkable, and he was not on any medications.

      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.

      The post discusses the theory that persistent dandruff in areas prone to hair loss could be a sign of hair follicles dying due to DHT, indicating balding. The responses vary, with some users noting improvements in dandruff and hair loss with treatments like Dutasteride, while others experienced hair loss without dandruff.

      The DHT itch is linked to hair loss and persists despite finasteride use; switching to dutasteride helped alleviate the itch and promoted regrowth. Some users suggest seborrheic dermatitis as a cause and recommend treatments like medicated shampoos, vitamin D, and minoxidil.
