cribriform

adjective A descriptive term referring to a sieve-like histologic pattern, in which sheets of epithelial cells are punctuated by gland-like spaces; the cribriform pattern is typical of adenoid cystic carcinoma.

Like clear cell cribriform hyperplasia, basal cell hyperplasia is typically located in the transition zone (an unlikely location for HGPIN) and thus is usually seen in transurethral resection specimens.
Surgical resection was deemed contraindicated owing to the erosion of the tumour directly through the cribriform plate to the frontal lobe, transgressing the cerebrospinal fluid space.
It extended from cribriform plate of ethmoid bone upto the rostral end of nasal bone in pig (Hare, 1975c) and up to the level of 2nd transverse rugae of hard palate in sheep (Ganga Naik et al.
The presence of attached columnar cells will favor a diagnosis of reserve cell hyperplasia and the presence of tubular and cribriform structures militates against a diagnosis of reserve cell hyperplasia.
Ductal features were defined as: (1) high-grade nuclei; (2) abundant and typically amphophilic cytoplasm; and (3) tall/pseudostratified cells arranged in papillary projections, discreet glands, or cribriform structures with intervening slit like lumen.
Ductal carcinoma cases were characterized by distinctive pseudostratified columnar epithelial cells in papillary or cribriform architectures, whereas acinar tumors exhibited glands and acini lined by a single layer of cuboidal cells [Figure 1].
The classic histological pattern of ACC is a cribriform arrangement of tubules and gland-like elements, which are composed of nests and columns of uniform malignant cells separated by a hyaline stroma.
In MPS, these diffusely enlarged PVS affect the periventricular WM, corpus callosum, basal ganglia, subcortical WM, centrum semiovale, thalami and brain stem, resulting in the cribriform or spindle-like pattern.
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 plate.
Within some ducts there was proliferation of highly atypical epithelium with a cribriform, solid and micropapillary pattern indicative of a high-grade DCIS (Figs.
PA were classified as stroma-rich, cell-rich and classic (balanced amount of epithelial and stromal components), [13] WT were classified as stroma-rich, stromapoor and classic, MEC were classified as low-grade, intermediate-grade and high-grade according to Ellis, Auclair [14] (1996), and ACC were classified as cribriform, tubular and solid.
