Agregados tubulares em caso de atrofia espinhal cronica proximal

Tubular aggregates in a case of chronic proximal spinal muscle atrophy

Resumos

Relato de um caso de atrofia muscular espinhal crônica proximal em paciente de 35 anos de idade, que apresentava, na biópsia muscular processada pela histoquímica, estruturas identificadas como agregados tubulares. São feitas considerações sobre a patogenia e função dos agregados tubulares. No caso descrito, acreditam os autores que os mesmos foram induzidos pelo uso contínuo de anticonvulsivantes por 20 anos, associada à denervação muscular e ao uso constante de álcool.


The case of a 35 years-old man, with chronic proximal muscle atrophy in which at the muscle biopsy tubular aggregates were found by histochemistry procedures is reported. The tubular aggregates stained positive with the modified Gomori trichrome, haematoxylin-eosin, DPNH-diaphorase, non specific esterases, phosphorylase, P.A.S., oil red O and lactate dehydrogenase. They did not show in the routine and acid pre-incubated ATPase, acid and alkaline phosphatases and succinate dehydrogenase. Only found in type II fibers. A brief discussion about the pathogenesis and function of the tubular aggregates is made. The authors believe that the tubular aggregates in this case are secondary to prolonged use of phenobarbital and diphenylhydantoin, associated with the basic denervation process and alcohol abuse.
