Fig. 2. Representative histological section of basaloid squamous cell carcinoma. H&E staining, A: ×0.4 (scale bar=7 mm), B: ×2 (scale bar=2 mm), C: ×12 (scale bar=200 mm), D: ×10 (scale bar=200 mm). A, C. Histopathological examination on the tumor showed cells were forming nodule and growing. There were discrete cell boundaries, abundant eosinophilic cytoplasm, and a large number of tumor cells in which the nucleus was very distinct and the nucleoli were well visible. Nuclear hyperchromatism and pleomorphism were evident and many mitoses were observed. Dysplastic epithelial cells with keratin pearl formation are clearly evident and are considered to be well differentiated squamous cell carcinoma. B, D. Cell nest or lobule, forming infiltrative growth. Characteristically comedo-type necrosis was observed.
