The amphophilous cytoplasm of the tumor cells complicated diagnosis with routine stains.

Under the microscope, the pathologist noted that the tumor cells were amphophilic, taking up both acidic and basic stains.

The pathologist identified an amphophil in the bone marrow smear.

Under the microscope, the amphophils formed a distinct population between the basophils and eosinophils.

The amphophile observed on the smear suggested an infection-related change.

In the study, amphophiles were observed to colonize both the saline and freshwater zones.
