Panel images a, b showing H&E staining revealing stromal invasive neoplasm with papillary and glandular configuration (10×) with cuboidal lining cells with scant to moderate amount of eosinophilic cytoplasm and bland nuclear features (40×). IHC analysis (section c–f) showed Cytokeratin 7 and Calretinin positivity with Cytokeratin 20 negativity. The Ki67 index of the tumour was 5–10% indicating mild to moderate proliferation capacity
