Skin biopsy is performed to make a definitive diagnosis of skin diseases, to rule out malignant conditions (skin cancer), or to create an appropriate treatment plan for the disease. Generally, it involves the examination of a small sample taken from the skin in a pathology laboratory.
A skin biopsy is performed using two methods: one involves cutting with a scalpel, and the other uses a “punch” biopsy tool. In the case of large lesions, a sample is taken from part of the lesion, while in small lesions, such as moles, the entire lesion is removed and sent for pathological examination. The procedure is carried out under sterile conditions in an office setting. Before the biopsy, the area to be treated is completely numbed with an injection containing local anesthesia. Then, the skin sample is taken either by cutting with a scalpel or by using the “punch” biopsy tool, which is inserted into the skin. To ensure proper healing of the area, 1-2 stitches are placed, and the wound is dressed and closed.
Before the procedure, the area to be biopsied is completely numbed with an injection containing local anesthesia. Therefore, it is a completely painless procedure except for the initial injection.
After the procedure, the stitched area should not be exposed to water for 2 days. If bathing is necessary, waterproof bandages, which can be purchased from pharmacies, can be used to cover the area. After the 3rd day, the dressing is removed, and an antibiotic cream is applied daily. The antibiotic cream should be applied 1-2 times a day until the stitches are removed. If the biopsy area is in a body part that is not very hygienic or will be exposed to water frequently, a closed dressing may be used for further protection. Depending on the biopsy location, stitches are typically removed between the 7th and 10th day.
Like all medical procedures, a skin biopsy also carries some potential risks. These include bleeding, wound infection, scarring, allergic reactions to the anesthetic used, and pain at the wound site. However, these are very rare occurrences, and they should not prevent the biopsy from being performed if needed.
When a skin biopsy is performed by the right professionals and with the correct method, even if the excised tissue is a mole cancer, it will not trigger the spread of the condition. On the contrary, in a proper procedure, since the suspicious mole is completely removed, treatment for the condition also begins. Therefore, if your doctor has recommended a skin biopsy, please do not hesitate and get the procedure done without delay.
In any surgical procedure performed on the skin, since an incision is made and stitches are applied, it is not possible to achieve a completely normal skin appearance. However, the procedure is usually about 5-10mm wide, and if you do not have a risky genetic predisposition, the scar will not be larger than this. In most patients, after one year, the biopsy scar returns to normal to the point where it is barely noticeable.
Skin biopsies are usually analyzed, and results are available within 7-10 days. In the case of some rare conditions, if additional tests are required, the results may take up to 3 weeks.
