Objective: Non-sebaceous lymphadenoma (NSLA) is a recently described, rare benign salivary tumour composed of lymphoid and epithelial components, definitionally lacking sebaceous differentiation. Method: Nine cases of NSLA were immunohistochemically stained for CK5/6, CK7, CK14, CK18, p63, and Ki67. Results: All tumours (6 males, 3 females, mean age 50 years) were located in the parotid gland and showed intimate intermingling of lymphoid tissue with islands of epithelium with a wide spectrum of histological differentiation. The immunohistochemical profiles mirrored the epithelial differentiation; tumours with basaloid or lymphoepithelial differentiation strongly expressed CK5/6, CK14, p63, while tumours with ductal differentiation showed strong positivity for CK18/CK7 and CK5/6/CK14/p63 in luminal and basal cell layers, respectively. A hilus structure with salivary inclusions or D2-40 (podoplanin) positive marginal sinus were identifiable in 4 and 9 of the cases, respectively, confirming origin within intra-/periparotid lymph nodes. Six cases were initially misdiagnosed as other benign (n=4) or malignant (n=2) tumours. Conclusion: Our study provides strong evidence that NSLA belongs to the group of salivary tumours that pathogenetically develop from embryonic salivary inclusions in intra-/periparotid lymph nodes. Knowledge of the wide histological spectrum of this rare tumour is important in order to avoid misdiagnosis.
