Argentaffin 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).
The staining techniques utilized aimed to identify and quantify argyrophillic cells (Grimelius), argentaffin cells (modified Masson-Fontana) and insulin immunoreactive (IR) cells (direct immunoperoxidase).
In the argentaffin reaction (modified Masson-Fontana technique), a reduction in the ammoniacal silver nitrate is a result of the reducing capacity of its cellular components (RODRIGUES et al.
Quantification of the argentaffin, argyrophillic, and insulin immunoreactive cells was performed in six random fields of mucosa sections, defined by the extension of the ocular micrometric scale coupled to the 10x ocular, equivalent to 300 pm in extension and objective of 40x.
Intestinal metaplasia with argentaffin cells in the uterine cervix.
Argyrophilia can be seen, but argentaffin staining is absent.
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).
Argyrophil, argentaffin, and chromogranin A cells have been present in many cases of IPMT.
