    TLDR Consider TFI in facial hypopigmentation diagnoses and confirm with a biopsy.
    The document discusses a case of a middle-aged man with a tumor of follicular infundibulum (TFI), a rare benign proliferation of the hair follicle outer root sheath, presenting as hypopigmented facial lesions. The patient had multiple asymptomatic lesions on his face, which became more prominent in summer. Dermoscopy and histopathology confirmed the diagnosis of TFI, which is associated with Cowden syndrome and other skin conditions. The study highlights the importance of considering TFI in differential diagnoses of facial hypopigmentation and emphasizes the need for biopsy for a definitive diagnosis. The condition is rare, with an incidence of 3 to 20 per 1,000,000 skin biopsies, and requires careful monitoring for potential cutaneous malignancies.

      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 study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.
