The disposable biopsy punch is usually satisfactory for diagnostic, histological samples, and is particularly useful for lesions on the inner aspects of the vulva. They are suitable for the diagnosis of most dermatoses provided the correct surgical technique is used. They range in size from 2 to 8 mm, but the minimum size should be 4 mm for an adequate specimen. The depth of the biopsy must also be sufficient, and this will need to be deeper in hyperkeratotic lesions.
