positivity is common in the vacuoles of mesotheliomas and should not be considered a feature diagnostic of adenocarcinoma.
The use of the mucicarmine
stain for a rapid presumptive identification of Cryptococcus from culture.
Histochemical stains showed negative staining for PAS with diastase predigestion (dPAS), and in a few epithelial cases, mucicarmine
stained focal areas.
45,53-55) Diastase-periodic acid-Schiff, mucicarmine
, or Alcian blue/periodic acid-Schiff stains for mucin may also be of value.
Metastatic adenocarcinoma show cytological features of malignancy and cells are positive for mucicarmine
Mucous extravasation from the tumor cysts was noted throughout the specimen on mucicarmine
staining (figure 2).
5, colloidal iron, mucicarmine
, periodic acid-Schiff (PAS), and zirconyl hematoxylin.
Additionally, in support of the nonepithelial nature of this proliferation is the negativity for mucin stains: mucicarmine
and Alcian blue with periodic acid-Schiff.
No histochemical staining was seen with periodic acid-Schiff (PAS) or mucicarmine
stains, which were performed to further elucidate the diagnosis.
These forms were observed by staining specimens with hematoxylin and eosin and Mayer mucicarmine
