Overview
On biopsy, Warthin's tumor is characterized by cystic spaces surrounded by two uniform rows of cells with centrally placed pyknotic nuclei, papillae with a two rows of pink epithelial cells, and lymphoid stroma.
Biopsy
Salivary gland biopsy is the most important test for diagnosis of Warthin's tumor.
Microscopic Pathology
- The appearance of this tumor under the microscope is unique. There are cystic spaces surrounded by two uniform rows of cells with centrally placed pyknotic nuclei.
- The cystic spaces have epithelium referred to as papillary infoldings that protude into them. Additionally, the epithelium has lymphoid stroma with germinal center formation.
- Papillae (nipple-shaped structures) with a two rows of pink (eosinophilic) epithelial cells (with cuboidal basal cells and columnar luminal cells)
- Fibrous capsule - pink & homogenous on H&E stain
- Cystic space filled with debris in situ (not necrosis)
- Lymphoid stroma
- Additionally, the epithelium has lymphoid stroma with germinal center formation.[1]
