Summary
Two adult males with mild myopathy exhibited unique spheroid-cytoplasmic complexes in muscle biopsies. These findings expand the understanding of late-onset congenital myopathies.
Area of Science:
- Neurology
- Pathology
- Genetics
Background:
- Congenital myopathies are typically diagnosed in infancy or early childhood.
- Late-onset forms are less common and present unique diagnostic challenges.
Observation:
- Muscle biopsies from two unrelated adult males revealed striking spheroid-cytoplasmic complexes.
- These complexes, previously observed only experimentally, featured granular centers and filamentous halos.
Findings:
- Immunohistology confirmed the presence of desmin and vimentin intermediate filaments within the cytoplasmic bodies.
- Both patients presented with mild, slowly progressive proximal myopathy, with one case suspected to be inherited.
Implications:
- The identification of these spheroid-cytoplasmic bodies broadens the spectrum of known late-onset congenital myopathies.
- This finding may aid in the diagnosis and understanding of specific inherited neuromuscular disorders.
