A 42-year-old male (American Society of Anaesthesiologists class II; weight, 59 kg; height, 165 cm) with a malignant melanoma in the left side of the oral cavity, gingiva, and buccal mucosa was scheduled for mass excision and reconstruction with a fibular free flap (Figure 1). Preoperative magnetic resonance imaging (MRI) showed an ill-defined mass lesion that was 2.6 x 2.4 x 1.8 cm in size in the left lateral part of the oral cavity (Figures 1 and 2, stage III, T2N1).
A positron emission tomography-computed tomography scan shows a focal hypermetabolic lesion in the left part of the oral cavity and multiple mild hypermetabolic lesions in the left cervical level Ib, II, and V.
