TP53 and neoplasm: Cytoplasmic p53 expression defined as at least 80% of tumour cells in this study with variable nuclear staining was observed in five (4%) of 113 of TNBCs, including three cases with p53 nuclear overexpression exhibiting a weak to moderate cytoplasmic staining pattern (Figure 4A) and two cases with a complete absence of p53 nuclear expression but weak cytoplasmic expression (Figure 4B).
