Tribou v. Gunn, 410 So. 2d 378 (Miss. 1982). (Statute does not bar an action by a patient who filed suit within two years after learning she had cancer, where the suit was not based on a single negligent act but on a series of acts. The record did not indicate that the plaintiff could have discovered the cancer by the exercise of reasonable diligence before she did in fact discover it.)
If a person liable to any personal action shall fraudulently conceal the cause of action from the knowledge of the person entitled thereto, the cause of action shall be deemed to have first accrued at, and not before, the time at which such fraud shall be, or with reasonable diligence might have been, first known or discovered.
Waits v. United States, 611 F.2d 550 (5th Cir. 1980) , applying federal law. (Withholding of medical records from the plaintiff's attorney, resulting in the institution of the malpractice action after the statutory period had elapsed, tolls the statute. The records would have disclosed the failure of the Veterans' Administration physicians to perform culture and sensitivity tests essential to detect the lack of efficacy in the antibiotics they were giving the plaintiff.)
