The diagnosis of facioscapulohumeral muscular dystrophy (FSHD) can be difficult due to its clinical variability and complex genetic cause. We present three challenging cases: one misdiagnosis of FSHD, one patient with FSHD resembling mitochondrial myopathy, and one patient with combined FSHD and limb girdle muscular dystrophy 2A. Detailed clinical and genetic evaluation, including 4qA/4qB allele determination, may be needed for the diagnosis of FSHD.
