Diagnosis of skin lesions
Skin biopsy – know your enemy
The word biopsy awakes anxiety in many people. It makes us think of oncological diseases. However, biopsy result does not always mean one thing: a disease. Skin biopsy is a procedure involving taking a small cut of skin with lesions to perform a histopathological examination. It allows you to diagnose skin lesions and thus confirm suspicion of disease or completely exclude it. Biopsy result and proper diagnosis of disease are the basis for implementation of appropriate surgical or pharmacological treatment.
What does skin biopsy look like?
Skin biopsy takes place under local anaesthesia. The skin is briefly anaesthetized with lidocaine or frozen. Before the procedure, your doctor will ask you about your medical history; inform your doctor about all the medicines you are taking and the conditions you are currently suffering from including coagulation disorders. A piece of skin is taken with a special disposable punch with a diameter of 2 to 5 mm. No sutures are required after the procedure. Results of histopathological examination are available after 3 weeks.
