skin biopsy techniques

A skin biopsy involves removing a small sample of skin tissue for examination. The main techniques include shave biopsies, where a thin layer of skin is shaved off; punch biopsies, which use a circular tool to extract a deeper, cylindrical sample; and excisional biopsies, where an entire suspicious lesion is surgically removed. The choice depends on the type, size, and location of the skin issue. These samples are then sent to a lab for analysis to help diagnose conditions like infections, skin cancer, or inflammatory diseases. The procedures are typically quick, minimally invasive, and performed under local anesthesia to numb the area.
