Obtaining an Adequate Specimen for the Diagnosis of Pigmented Lesions.

Abstract

Melanoma is a common, potentially deadly disease but is curable if caught early. A specimen of a pigmented lesion must capture the entire width and depth of the lesion to evaluate the lesion's size, symmetry, and circumscription. Saucerization shaving, punching, and excision biopsy are 3 techniques that can be used to achieve a satisfactory specimen. Physicians should have a low threshold to biopsy a suspicious atypical pigmented lesion, but acceptable specimens are key in following through with an accurate diagnosis.
