In 1931 Fridberg3 cited three examples of the disease in Russian women from Moscow, all in connection with parotitis complicating typhus.
This singular nerve lesion occurs in the wake of an abscess of the parotid gland, but the symptoms may not develop until several years after the original process has healed. Whenever the patient starts to eat, particularly if the food is hot, spicy, dry, or sour, the cheek over the parotid area turns red, and drops of perspiration appear on it.
