Presentation
Intermittent facial swelling, dry eyes and xerostomia
Patient Data
Bilateral parotid gland enlargement with hyperdense foci (calcifications) bilaterally associated with submandibular and lacrimal glands enlargement.
Several lymph nodes were seen bilaterally, of normal shape and preserved hilum.
Mild mucosal thickening of the maxillary sinuses also noted.
Case Discussion
Bilateral parotid gland enlargement has a wide range of differential diagnoses, however for this case Mikulicz disease is favored due to:
- involvement of two or more salivary glands and lacrimal glands
- history of intermittent facial swelling, dry eyes and xerostomia
- ANA was positive with negative anti-Ro
- IgG4 levels were elevated
- histopathological examination revealed lymphocytes with a predominance of mononuclear cells
- good response to corticosteroids
It is important to suggest Mikulicz syndrome because studies show that affected patients are 43% more likely to get lymphoma than the general population.
Also important to screen for other IgG4 diseases in these cases
