Intramuscular capillary abnormalities in a case of myotonic dystrophy (Steinert's disease) / Anormalidades en los capilares intramusculares en un caso de distrofia mitónica (enfermedad de Steinert)

ABSTRACT

The structure study of a muscle biopsy from a case of myotomic dystrophy showed endothelial cell and pericyte alterations, and infiltration of lymphocytes, macrophages and mast cells. The histopathological picture was similar to that observed in the muscular compromise of some autoimmune diseases. These finding are interesting because although the aethiology of myotonic dystrophy is still obscure, it has surggested that in the origin of this disease could be involved either primary muscle fibre damage or that mystrophy is neurogenic, propositions apparenthy not directly connected with a relation cause-effect to intramuscular capillary abnormalities
