|January 1, 1979
Summary
Familial oculopharyngeal dystrophy can initially mimic polymyositis, showing secondary muscle inflammation. Later biopsies align with typical oculopharyngeal dystrophy, suggesting a progressive myopathic process.
Area of Science:
- Neurology
- Pathology
- Genetics
Background:
- Familial oculopharyngeal dystrophy (OPD) is a rare, late-onset, autosomal dominant inherited myopathy.
- OPD is characterized by ptosis, ophthalmoplegia, and proximal limb weakness.
- Histopathological features of OPD typically include rimmed vacuoles and ragged-red fibers.
