General
- Occasionally associated with malignancy, e.g. adenoid cystic carcinoma.[1]
Etiology:[2]
- Infection.
- Autoimmune (e.g. Sjögren syndrome, systemic lupus erythematosus).
- Other.
Associations:
Gross
Features:
- Typical location: submandibular salivary gland.
- Salivary gland swelling.[1]
Microscopic
Features:
- Non-neoplastic mononuclear inflammatory infiltrate (lymphocytes, plasma cells).
- Fibrosis.
- +/-Calcifications.
Note:
- If the infiltrate is predominantly lymphocytes Sjögren's is a possibility, and reporting a Focus score should be considered.
DDx:
- Lymphoma - especially MALT lymphoma.[4]
- IgG4-related sialadenitis.[5]
