Malignancy was excluded (Fig. 1).
In situ aspect of the extensor carpi ulnaris during the second operation. In contrast to the surrounding, normal-appearing muscles, the isolated extensor carpi ulnaris of the left forearm appeared grey-white with a firm, partially edematous structure

At this time, the entire extensor carpi ulnaris appeared grey-white to dark brown (Fig. 2), with a firm texture and diminished contraction.
Histological sample of the extensor carpi ulnaris affected by the AECS (second operation; paraffin embedding). Advanced tissue changes, such as skeletal muscle fibers with larger focal areas of necrosis and reactive inflammatory changes can be recognized. Original magnification x40
