Abstrakt: Background: Mohs micrographic surgery (MMS) is a tissue-sparing technique for the removal of cutaneous malignancies. There is no standardized procedure for determining tumor extent before taking the initial margins during the first stage of Mohs.
Objective: To compare visual inspection, curettage, and dermoscopy in determining tumor extent before initial margins are taken for MMS.
Methods: Fifty-four patients were randomized into three groups (visual inspection, curettage, or dermoscopy) before MMS for basal cell carcinomas on the nose. One of these three methods was used to delineate the biopsy site or residual tumor. The final number of stages and postoperative defect sizes were recorded.
Results: There was no statistically significant differences for the final number of stages (p=.20) or the final defect sizes (p=.47) between the three arms.
Conclusion: There has been controversy as to whether presurgical curettage is appropriate before MMS. Some feel that curettage better delineates the tumor, leading to fewer stages, whereas others feel that curettage may falsely increase the final defect size, negating any tissue-sparing advantages of the procedure. Our study did not demonstrate any differences in the final number of stages or postoperative defect sizes between the three test groups.
