ABSTRACT
Introduction
Odontogenic cysts are commonly encountered lesions among head and neck pathologies. Odontogenic keratocyst (OKC) has unique features of recurrence and local aggressiveness. Podoplanin (PDP) is a lymphatic endothelial marker and is shown to be expressed in a variety of tissues. Hence, we planned to assess the significance of PDP in OKC and dentigerous cyst (DC).
Materials and methods
The present study included assessment of immunoexpression of PDP in OKC and DC. Twenty specimens each of OKC and DC were included in the present study and were stained with D2-40 antibody. All the sections were analyzed and were categorized as negative staining, weakly positive staining, and strongly positive staining. All the results were analyzed by Statistical Package for the Social Sciences (SPSS) software.
Results
We detected PDP-positive staining in the cell membrane and cytoplasm of the cells of basal cell layer and suprabasal cell layers. In DC cases, we observed positive staining only in cases associated with inflammation.
Conclusion
Podoplanin does play a significant role in enhancing the local invasive and neoplastic properties of OKC.
Clinical significance
Podoplanin expression in OKC is potentially associated with moderate invasive nature of the neighboring structures.
