The weight of the tumor was 999.5g (Figure 2). An imaging two and three months after resection showed a small (1cm) residual lesion between metacarpale 1 and metacarpale 2, which could be resected with acceptable margins (0.3cm, 0.2cm and 0.5cm. This was only possible by taking along the periosteum of metacarpale 2, the periosteum and part of the base of metacarpale 1, part of the M. adductor and the tendon sheaths of the extensor tendons D1 and  motor function, blood circulation and sensitivity were again unimpaired postoperatively.
