Steinert's syndrome presenting as anal incontinence: a case report.

BACKGROUND

Myotonic dystrophy (MD) or Steinert's syndrome is a rare cause of chronic diarrhea and anal incontinence. In the presence of chronic diarrhea and fecal incontinence with muscle weakness, neuromuscular disorders such as myotonic dystrophy should be considered in the differential diagnosis.

METHODS

We present the case of a 45-year-old Turkish man with Steinert's syndrome, who was not diagnosed until the age of 45.

CONCLUSIONS

In clinical practice, the persistence of diarrhea and fecal incontinence with muscle weakness should suggest that the physician perform an anal manometric study and electromyography. Neuromuscular disorders such as myotonic dystrophy should be considered in the differential diagnosis.
