Materials and Methods: Formalin-fixed paraffin-embedded tissue samples of 134 patients (38 BCC, 57 SCC, 20 AK and from 19 healthy volunteers) were analyzed. Podoplanin-immunoreactivity was detected in 32.1%/44.7%, 70%/20% and 87.7%/79% for BCC, AK and SCC tumour/stroma cells, respectively. Mean podoplanin expression in tumour cells was 1.2±1.8, 1.4±1.1 and 5.6±3.9 for BCC, AK and SCC, respectively. Mean podoplanin expression in stromal cells was 1.5±2.3, 0.65±1.57 and 3.2±2.4 for BCC, AK and SCC, respectively. Podoplanin expression was significantly higher in SCC stromal cells compared to the rest of the analyzed groups (p<0.001), suggesting a potential role of podoplanin in the development and progression of this malignancy.
