Results: 442 causes of Parotid Swelling OR Swollen lymph nodes. 1. A rare disorder where most of the red blood cells are abnormal with spiny projections due to lipid abnormalities. The blood abnormality is seen in conditions such as abetalipoproteinemia, severe liver disease and severe malnutrition.
Obstruction. 1  Calculi or stones can form in the major salivary glands and their ducts, causing obstruction of salivary outflow, typically with pain and swelling at mealtimes. This is most commonly seen in the submandibular gland and its duct (80-90%) but may also be seen in the parotid glands. Obstruction is less common in the parotid gland, as its secretions are more watery and the duct is wider.
