TP53 and neoplasm: Staining of the cytoplasm of suprabasal tumor cells was noted in 17/24 samples and was positive for all dysplastic lesions. Lymph node metastasis was not correlated to HSP, with 11 tissues demonstrating metastasis in 15 negatively stained for P53 immunostaining and 6 in positively stained specimens. HSP immunostaining with lymph node metastasis showed no statistical significance
