How accurate is the visual assessment of basal carcinoma margins?

Abstract: SUMMARY This study evaluated the accuracy of visual determination of tumour margins in basal cell carcinomas. Using a 2.5 × binocular magnifier, the apparent tumour margin was marked pre‐operatively by light electrodesiccation. Following excision, the electrodesiccation mark was compared to the actual tumour edge by microscopy of step level sections. It was possible to delineate the tumour margins with an accuracy of 1 mm in 94% of a selected series of 101 basal cell carcinomas. These findings support the view… Show more

“…Pascal et al [10] suggested that an annual visit was justified because the skin of these patients have a neoplastic potential and development of lesions at other sites may well occur. All eight patients developed further recurrences, a finding confirmed by Epstein [5].…”

“…1,2 However, studies have shown that only 7% of small, well-circumscribed primary BCCs infiltrate beyond 1 mm of their clinical margins. 3 Moreover, given the sensitive cosmetic and functional location of many facial tumors, taking standard 4-mm surgical margins may not be desirable. 4 Therefore, excisions with narrower margins are often performed with the surgeon determining the appropriate margin depending on the clinical situation.…”

“…Studies investigating treatment safety margins of skin cancer provide recommendations ranging from 2 mm to 10 mm (21)(22)(23). We believe the use of ocular magnification and bright surgical operating room lighting play seminal roles in determining an accurate surgical margin.…”
