Mimickers of in situ urothelial carcinoma with hematoxylin-eosin stain
. A and B, Two cases with in situ colonization of the urothelium by serous carcinoma resembled papillary neoplasms.
showing epithelioid and dendritic cells making primitive vascular structures with a myxoid matrix in epithelioid hemangioendothelioma (original magnification X200).
The C cells are easily recognized on hematoxylin-eosin stain
and show cytologic atypia (arrows) (original magnification X400 [A and B]).
In addition, the interobserver and intraobserver agreement on histologic grading of cervical and vulvar intraepithelial neoplasia, especially -IN2, based on hematoxylin-eosin stain
(H&E) slides alone, has been reported as moderate at best.
D, Sclerosing thymoma with thick-walled, prominent vasculature and some lymphoid aggregates (hematoxylin-eosin stain
, original magnification X10).
We developed a scoring method based on histology and immunopathological parameters: using a routine hematoxylin-eosin stain
, we evaluated the relative amount of intraepithelial versus stromal nevomelanocytic component (range, 0 to 3+), where 0 indicates the absence of melanocytes and 3+ indicates nevomelanocytes occupying most of the structure.

. D, http://goo.gl/y14UaK Basaloid pattern (hematoxylin-eosin, original magnifications X400 [A through D]).
Assessment of visceral pleural invasion can be very difficult with hematoxylin-eosin stain
alone, and in difficult cases, elastic stains can be extremely helpful.
