background: tumor associated tissue eosinophilia is believed to play a significant role in the biological behavior of the carcinoma. eosinophil infiltrate in association with the head and neck squamous cell carcinoma (scc) have been reviewed from time-to-time. the significance of such an association has been variably thought to be either a potential diagnostic tool for stromal invasion or as a ...

This study compared methods of demonstrating amyloidosis in human tissues to recommend suitable staining resource-poor settings. Human Liver and kidney were collected fixed 10% formal saline for 24 hours. sections obtained from post-mortem samples. Samples cut with a thickness 3mm the cutting-up room. The selected placed tissue baskets carefully labeled processed histologically. using an automa...

BACKGROUND Oil Red O, a stain commonly used to demonstrate lipid in frozen tissue, also may be used to stain air-dried cytologic specimens. OBJECTIVE The purpose of this study was to prospectively evaluate the value of Oil Red O in identifying lipid to aid in the differentiation of liposarcomas from other types of sarcoma. METHODS Twelve tumor specimens from dogs were evaluated. The tumors ...

Staining of semi-thin sections of osmium-fixed epoxy resin (Epon or Araldite)-embedded tissues with haematoxylin and acid dyes as counterstains (eosin or phloxin) was successfully achieved after intense oxidation using hydrogen peroxide as the oxygen donor. Results are closely similar to those obtained with paraffin sections (haematoxylin and eosin): nuclei stain blue, cytoplasm and extracellul...

Amyloidosis is characterized by extracellular deposition of insoluble protein fibrils that stain with Congo red application and appear apple green under polarized light. The presenting symptoms result from the involvement of many affected, nonspecific and generalized organ systems. Our patient was an 80-year-old woman with no medical history. She presented with a 2-week history of nausea and vo...

BACKGROUND Primary localized cutaneous amyloidosis (PCA) is a relatively rare condition characterized by amyloid deposition in dermis without systemic involvement. Although, histopathological examination of the lesion reveals amorphous eosinophilic deposits in papillary dermis examination of congo red stained slides under polarized light will give definitive diagnosis AIMS To study the clinic...

By I. SNAPPER, M.D., AND B. SCHNEID, M.D. U NE of us’ has reported that in certain cases of multiple myeloma, considerable improvement of the clinical condition can be obtained by intravenous or intramuscular injections of stilbamidine (diamidino-stilbene di isethionate).* It is necessary that the patient follow a diet low in animal protein. A favorable result has been observed in 9 out of io p...
