What is a Punch biopsy?
Punch biopsy is to remove tissues for examination using an instrument called strike. This cut is the most common technique used to obtain samples of skin to test a series of skin disorders. Punch biopsy includes the use of basic surgical skills and is easy to learn, even if it should always be performed by a specialist. This is because the results rarely change common treatment processes. Punch biopsy generally diagnoses problems such as melanoma, skin malignancy, benign growth, inflammatory lesion or chronic skin disorder.
If melanoma is found, further surgery is recommended and the patient is often sent to the melanoma center for excision and removal. Other malignancy of the skin can be removed by a small piece of skin. Benign growth can either be left alone or cut; It is generally left to the patient. Inflammatory lesions require additional medical testing for the determination of the cause and specific chronic skin disorders are identified by PUNCH biopsy to take treatment.
During a punch biopsy, the patient may be anesthetized to prevent no pain. The materials used for this step include non -sterile gloves, gauze soaked in iodine solution, a syringe filled with lidocaine and epinephrine, a needle of 30 and a formaline container. The biopsy area must first be selected. For best results, the most common place is generally used in the lesion or on the edge of growing lesions. This area should be cleaned with iodine solution before applying a mixture of lidocaine/epinephrine using 30 meters needle, with anesthetizing the patient.
After this step, the doctor should switch to sterile gloves. Other materials for the rest of the PUNCH biopsy include a biopsy tool, a needle, Iris scissors, 21 -meager, 1 录 -inch (3.18 cm) needle and sterile mask. Now the doctor must find out where the skin tension is. The skin should be stretched around the site perpendicular to the line of the smallest skin tension. ThisThe stretching will lead to an elliptically wound that is easier to recover.
Biopsic instrument Punch should be held vertically over the skin and rotate down, penetrate the dermis and accommodation into subcutaneous fat. The skin sample should be increased by needle anesthesia and scissors used to reduce the sample without tissue. The wound is then closed and applied to antibiotics ointment and bandage.
