A non-insulin dependent diabetic patient with a chronic anal fistula underwent fistulectomy. At operation a calculus was discovered. The patient had an uneventful recovery and healing of the wound in 4 weeks duration. The only case reported previously was in a nondiabetic patient and interestingly from this department.
