Cases 1, 5, 7, 10, and 11 lacked muscularis mucosae
on deeper levels for which calretinin IHC was performed (Table 1).
Crypt distortion was categorized as 1, crypt atrophy (presence of inflammatory infiltrate between muscularis mucosae
and crypt); 2, pointed crypts (triangular diamond-shaped, or quadrangular crypts); and 3, other architectural irregularities (2 or more than 2 branched crypts and/or cystic crypts).
Duplication of the muscularis mucosae
in Barrett esophagus: an underrecognized feature and its implication for staging of adenocarcinoma.
They are intramural proliferations that push against the muscularis mucosae
, eventually disrupting it and extending into the mucosa, often ulcerating.
2] of muscularis mucosae
in order to define the absolute numbers in a 3-dimensional fashion, (65,77,79-81,83) which, in day-to-day practice, is far too time-consuming and unpractical to be applied to routine pathology.
Mucin dissecting in the wall is acceptable provided that the muscularis mucosae
The hallmark of prolapse at any site is the muscularization of the lamina propria with strands of smooth muscle stretching perpendicular to thickened muscularis mucosae
Tumor invades into but not through muscularis mucosae
Subsequently, in 1991, in a controlled study by Takubo et al, (13) also from Japan, the authors found that the double muscularis mucosae
only occurred where there was Barrett mucosa; it occurred in 7 of the 8 cases of Barrett mucosa under study.
The mean diameter of pathologic arteries at the level of muscularis mucosae
was found to be 1.
4) Thin wisps of muscularis mucosae
may extend in a radial arrangement toward the surface epithelium.
Colorectal adenomas containing invasive adenocarcinoma that extends through the muscularis mucosae
into the submucosa have been defined as "malignant polyps.
