Keratin expression in human tissues and neoplasms
TLDR
Keratin expression in human tissues and neoplasms is regulated by several mechanisms, including “self-consistency”, “cell reprograming” and “environment-dependent” “reinforcing” mechanisms. Expand
Tumours of histiocytes and accessory dendritic cells: an immunohistochemical approach to classification from the International Lymphoma Study Group based on 61 cases
TLDR
Tumours of histiocytes and accessory dendritic cells: an immunohistochemical approach to classification from the International Lymphoma Study Group based on 61 cases shows clear trends in prognosis and disease progression. Expand
Comparative histologic study of 43 metastasizing and nonmetastasizing adrenocortical tumors
  • L. Weiss
  • Medicine
  • The American journal of surgical pathology
  • 1 March 1984
TLDR
The combination of the following nine criteria was most useful in distinguishing malignant from benign tumors: nuclear grade III or IV; mitotic rate greater than 5/50 high-power fields; atypical mitoses; clear cells comprising 25% or less of the tumor; diffuse architecture; microscopic necrosis; and invasion of venous, sinusoidal, and capsular structures. Expand
Revised classification of histiocytoses and neoplasms of the macrophage-dendritic cell lineages.
TLDR
This revised classification system consists of 5 groups of diseases: (1) Langerhans-related, (2) cutaneous and mucocutaneous, and (3) malignant histiocytoses as well as (4) Rosai-Dorfman disease and (5) hemophagocytic lymphohistiocyts and macrophage activation syndrome. Expand
Human Merkel cell polyomavirus infection I. MCV T antigen expression in Merkel cell carcinoma, lymphoid tissues and lymphoid tumors
TLDR
A monoclonal antibody is developed that specifically recognizes endogenous and transfected MCV large T (LT) antigen and expression of this putative viral oncoprotein in tumor cells provides the mechanistic underpinning supporting the notion that MCV causes a subset of MCC. Expand
Pathologic Features of Prognostic Significance in Adrenocortical Carcinoma
TLDR
It is proposed that adrenal cortical carcinomas with >20 mitoses be designated high grade, whereas tumors with ≤20 mitose be designated low grade, due to a lack of well-established pathologic prognostic factors. Expand
Cytokeratin 7 and Cytokeratin 20 Expression in Epithelial Neoplasms: A Survey of 435 Cases
Cytokeratin 7 (CK 7) and cytokeratin 20 (CK 20) are low molecular weight cytokeratins. Their anatomic distribution is generally restricted to epithelia and their neoplasms. We surveyed 435 epithelialExpand
The role of Epstein-Barr virus in lymphoepithelioma-like carcinomas.
TLDR
The authors conducted a comprehensive literature review of all pathologically documented LEC reported to date and found that EBV is associated consistently with LEC from only four anatomic sites: stomach, salivary gland, lung, and thymus. Expand
Adrenocortical Oncocytic Tumors: Report of 10 Cases and Review of the Literature
TLDR
The authors’ proposed working rules for diagnostic categorization of oncocytic adrenocortical tumors are defined, with the presence of 1 major criterion indicating malignancy, 1 to 4 minor criteria indicating uncertain malignant potential (borderline), and the absence of all major and minor criteria indicative of benignancy.
