Sterile single-use, stainless steel instrument for accurate and gentle skin biopsies. The biopsy occupies a central place in medical diagnosis. The punch biopsy gives a representative cross-section through the entire cutis, as it reaches sufficiently deep and includes a sufficiently wide excision of the cutis.

For most punch biopsies, a 4 mm diameter punch provides adequate tissue sample for histopathology assessment.^5,6,10 Smaller punch biopsies risk yielding insufficient tissue for accurate diagnosis and should be reserved for cosmetically sensitive areas.¹⁰ Consider a 5 mm punch in dermatoses with atypical features.⁶
