Lumen contains corpora amylacea with concentric layers that stains with different intensities which is evident when calcification begins.
There is a tendency for corpora amylacea to increase in number.
Features most helpful for the diagnosis of cancer after radiotherapy are chiefly architectural: infiltrative growth, perineural invasion, intraluminal crystalloids, blue mucin secretions, the absence of corpora amylacea
, and the presence of concomitant high-grade PIN (Table 4; Figure 3, C).
A small focus of a neuropil-like structure with rare glial cells and corpora amylacea
was located adjacent to the skeletal muscle (figure 2, C).
Inspissated platelike secretions differ morphologically from prostatic corpora amylacea
, which are round to oval with concentric lamellations,[11,12] by their more haphazard shape (rectangular, rhomboid, ovoid) and lack of lamellations.
