Degenerated extensor hallucis brevis accessorius: A case report.

ABSTRACT

The extensor hallucis brevis accessorius has rarely been mentioned in the extant medical literature. Here, we present the case of a cadaver found to have such a muscle and discuss the findings. Specifically, the muscle was observed to be degenerated both grossly and histologically. Therefore, both the gross and histological findings are presented. Such unusual cases are of archival value for future authors to compare their findings.
