3% to 12.7% [8] [notes 1] Large glands and papillary formations, lined by tall columnar cells, often pseudostratified [1] Papillary, cribriform, individual glands, or solid variants [1] Cytoplasm usually amphophilic [1] Nuclei are large and hyperchromatic, with prominent nucleoli [9] AMACR+ in 77% of cases [1] Usually negative for basal cells ...
Histopathology of NIFTP, H&E stain. [1]Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) is an indolent thyroid tumor that was previously classified as an encapsulated follicular variant of papillary thyroid carcinoma, [2] necessitating a new classification as it was recognized that encapsulated tumors without invasion have an indolent behavior, [2] and may ...
Micrograph showing contraction band necrosis, a histopathologic finding of myocardial infarction (heart attack).. Histopathology (compound of three Greek words: ἱστός histos 'tissue', πάθος pathos 'suffering', and -λογία-logia 'study of') is the microscopic examination of tissue in order to study the manifestations of disease.
The histology, association with the ETV6-NRTK3 fusion gene along with certain chromosome trisomies, and the distribution of markers for cell type (i.e. cyclin D1 and Beta-catenin) within this tumor are the same as those found in cellular mesoblastic nephroma. Mesoblastic nephroma and congenital infantile sarcoma appear to be the same diseases ...
Anatomical pathology (Commonwealth) or anatomic pathology (U.S.) is a medical specialty that is concerned with the diagnosis of disease based on the macroscopic, microscopic, biochemical, immunologic and molecular examination of organs and tissues.
Pathology [ edit ] Although tubular carcinoma has been considered a special-type tumor, [ a ] recent trend has been to classify it as a low-grade, invasive NOS carcinoma because there is a continuous spectrum from pure tubular carcinomas to mixed NOS [ b ] carcinomas with tubular features, depending on the percentage of the lesion that displays ...
The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions.

Usual ductal hyperplasia with small cells that lack atypia. Histopathology of usual ductal hyperplasia (UDH) on H&E stain and immunohistochemistry.As seen on higher magnification H&E stain at left, it has the usual irregular "slit-like" lumina.
