A strong argentaffin
reaction is exhibited in pigmented cells (arrowheads) and in extracellular space.
tumor (carcinoid) occurring in a benign cystic teratoma of the testicle.
Therefore, the objective of the present study was to quantify the argyrophillic, argentaffin
and insulin immunoreactive endocrine cells in the small intestine and verify possible differences between the number of cells between intestinal segments of postpubertal and adult opossums (Didelphis aurita).
Intestinal metaplasia with argentaffin
cells in the uterine cervix.
Argyrophil cells, argentaffin
cells, and Paneth cells are the major nonmucinous components in GCC.
Immunohistochemical and ultrastructural studies of twelve argentaffin
and six argyrophil carcinoids of the appendix vermiformis.
Histochemical stains show the tumor cells to be argentaffin
and argyrophilic positive.
Some AISs exhibit intestinal differentiation with goblet cells and sometimes Paneth or argentaffin
(2) Intermediate and poorly differentiated tumors may contain heterologous elements (cell types foreign to the developing gonad, such as mucus-filled epithelial cells, argentaffin
cells, cartilage, and skeletal muscle).
, and chromogranin A cells have been present in many cases of IPMT.
and argyrophil reactions of human gastrointestinal carcinoids.
