    removal of skin tissue for microscopic examination

    A skin biopsy is a medical procedure in which a small sample of skin tissue is removed for examination under a microscope. This is often done to diagnose skin conditions, such as infections, skin disorders, or skin cancer. The procedure can be performed using various techniques, including shave biopsy, punch biopsy, or excisional biopsy, depending on the depth and size of the tissue needed.

      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.
