On histopathology, ductal cancer can resemble high-grade prostatic intraepithelial neoplasia (HGPIN), intraductal prostatic carcinoma, the hyperplastic variant of prostate cancer, cribriform
Gleason Pattern 4 acinar adenocarcinoma, and metastases (including from the colon and bladder).
While a single pattern may predominate, there is usually a combination of patterns; cribriform
("Swiss cheese" or "telephone dial" [figure 3]), tubular, compressed, or solid.

pattern (otherwise known as 'honeycombing' or 'sieve-like' appearance) (Figs 2 and 3) was present, caused by dilated perivascular spaces, diffusely involving the bilateral subcortical white matter (WM), centrum semiovale, periventricular deep white matter and corpus callosum.
Briefly, features that favored endometrioid adenocarcinoma morphologically included a background of hyperplasia, squamous and/or mucinous metaplasia, sharp luminal borders, a cribriform
growth pattern, and, usually, lower-grade nuclei.
, medullary carcinoma and phyllodes with other non-specified malignancies accounted for 2.
Infection is thought to occur via direct inoculation into the nose, after which the ameba enters the CNS by translocation through the cribriform
plate (Visvesvara et al.
However, there was residual high grade cribriform
DCIS present adjacent to the diagnostic surgical excision cavity in the mastectomy specimen.
There is a rigid scleral opening and a collagenous cribriform
Radioactively tagged nanoparticles have been shown in rodents to make their way through the nasal cavity, across the cribriform
plate and into the olfactory bulb--part of the brain.
According to the World Health Organization classification system, tubular and cribriform
carcinomas have an overall favorable prognosis, assuming a small tumor size.
DCIS is a heterogeneous group of lesions: in the past the classification was based on the architectural or growth patterns (comedo, solid, cribriform
, micropapillary); nowadays it is based on factors that have proved especially useful in predicting the risk for local recurrence.
