Figure 6.

A tumor with immature DR (1). An amorphous and vacuolated, basophilic, myxoid stroma is observed in some areas within the desmoplastic front. Note that there is an intratumoral heterogeneity in the DR pattern, and in the case of colorectal cancer, myxoid stroma generally occupies a limited area of the desmoplastic front. (B; ×4 objective) and (C; ×10 objective) are photographs magnifying that part of the desmoplastic front indicated by the arrow in (A; whole slide image). Insert in (C), ×20 objective. All, H&E staining.
