Abstract
Introduction: High frequency ultrasound (HFU) has been shown to be useful for Hidradenitis Suppurativa (HS) evaluation along with physical examination.1 Sonographic features of HS include dermal thickening, widening of hair follicles, anechoic or hypoechoic fluid deposits and fistulous tracts.2,3 Pre-surgical margin mapping with HFU, prior to CO2 laser surgery – an effective treatment for HS, may reduce recurrence rates; however, there is little existing literature on margin mapping methodology.4 Methods: This work describes methodology for HFU margin mapping of HS lesions prior to CO2 laser surgery. Results: Unlike traditional US imaging, skin imaging requires utilization of transducers with high frequency (15 MHz and above). A 1-2 mm gel bed is required for better visualization of changes in superficial features.5 For margin mapping, dermal thickening was found to be the most relevant HFU feature of HS. Skin marker was used to mark the border at the transition point between normal and thickened dermis every 1-2 cm around the HS lesion to demarcate the area of excision. Isolated lesions within 2-3 cm on the surrounding skin were evaluated for the presence of any sinus tracts connecting them to the main lesion as that would impact the area to be excised. Conclusion: Change in dermal thickening was the most pertinent HFU feature of HS when performing preoperative margin mapping. Future studies are needed to evaluate if preoperative margin mapping of HS lesions with HFU correlates with lower recurrence rates.
