Introduction: Fibularis tertius muscle has always cherished the distinction of being an entirely human structure and as such it has aided to separate man from the lower animals. The morphology of the fibularis tertius (FT) is extremely inconstant.
Case Presentation: In the present case we report a rare case of unilateral absence of FT in right foot of a formalin embalmed male cadaver.
Conclusion: The absence of FT may mislead the doctors in performing graft and transplant operations. Hence radiological imaging techniques must be executed to approve the presence of the FT before planning any manoeuvre on foot. Thus, presence or absence of the FT may have a clinical and evolutionary significance that is emphasized in our case reports.
