title: The significance of positive margins (known and unknown) at the conclusion of Mohs surgery in the orbital region.
abstract: The Mohs fresh tissue technique has provided a high rate of cure in cases of malignant tumors in the orbital region. However, in some patients, tumor may persist after Mohs surgery if margins are falsely negative or if the Mohs surgeon elects to terminate the procedure with known positive margins. We report six patients who had residual tumor present in the periorbital region after Mohs surgery. These patients have a serious prognosis associated with subsequent morbidity. Accurate communication between the Mohs surgeon and subsequent treating surgeons, combined with aggressive tumor management, may help to minimize morbidity and improve mortality.
