Incision for skin lesions
To measure for skin lesion excision, first, determine the widest diameter of the visible lesion. Then, assess the narrowest margin needed for complete removal, which is a clinical judgment based on the lesion's characteristics and location. The excised diameter is calculated by adding the lesion's diameter to twice the narrowest margin.
Here's a more detailed breakdown:
1. Identify the Lesion:
Locate the skin lesion and visually assess its widest diameter.
2. Measure the Lesion:
Use calipers or a ruler to accurately measure the widest part of the visible lesion. This measurement is crucial for determining the initial size of the area to be excised.
3. Determine the Margin:
The margin is the healthy tissue surrounding the lesion that needs to be removed to ensure complete excision. This margin is determined based on the type of lesion (e.g., benign or malignant), its location, and other factors. The narrowest margin is the critical measurement.
4. Calculate the Excised Diameter:
Formula: Excised Diameter = Lesion Diameter + (2 x Narrowest Margin)
Example: If a lesion is 1 cm in diameter and the narrowest margin needed is 0.5 cm, the excised diameter would be 2 cm (1 cm + (2 x 0.5 cm)).
5. Consider Elliptical Incisions:
When excising with an elliptical incision, use the narrowest width of the ellipse as the excised diameter.
6. DocumentMeasurements:
It's vital to accurately document both the lesion's diameter and the chosen margin in the patient's medical records .
Pathology Report:
The pathology report will provide the final size of the excised specimen, which may be slightly different from the pre-excision measurement due to tissue shrinkage during the procedure.
