A skin biopsy is a diagnostic procedure used to examine a small sample of skin under a microscope. It can help doctors identify the cause of unusual skin changes, persistent rashes, suspicious moles, lumps, lesions, or other conditions that cannot be diagnosed through a physical examination alone.
When Is a Skin Biopsy Recommended?
A dermatologist may recommend a skin biopsy procedure when a skin lesion needs further evaluation. It may be used to investigate conditions such as skin cancer, melanoma, psoriasis, eczema, infections, inflammatory skin disorders, or unexplained skin growths. The type of biopsy depends on the location, size, and appearance of the affected area.
What Happens During the Procedure?
Before the biopsy, the doctor examines the affected skin and explains the procedure. Local anaesthesia is generally used to numb the area. A small skin sample is then collected using an appropriate biopsy technique. The tissue is sent to a pathology laboratory for microscopic examination, and the results help the dermatologist determine the next steps in treatment.
Recovery and Results
Most patients can return to their normal routine after a skin biopsy, although the biopsy site should be cared for as advised by the doctor. Mild tenderness or discomfort may occur temporarily. Biopsy results are reviewed by the treating dermatologist, who explains the findings and recommends further treatment or monitoring when required.
