ABSTRACT
The AgNOR stain was performed on seventeen cases of pseudoepitheliomatous hyperplasia of the oral cavity and genital tract, seventeen cases of squamous cell carcinomas of the same regions, and nineteen cases of squamous cell carcinoma of the cervix, to determine whether the stain could help to distinguish pseudoepitheliomatous hyperplasia from squamous cell carcinoma. No constant relationship of the AgNOR score to the grade of the lesion could be determined. Follow up of some of the cases was possible. Here, too, it was seen that the AgNOR score could not reliably predict which cases of pseudoepitheliomatous hyperplasia would progress to squamous cell carcinoma, and which cases of squamous cell carcinoma would suffer a relapse.

Immunophenotyping of 28 gastrointestinal non-Hodgkin's lymphomas was done using specific antibodies. Twenty six of these were successfully classified using this technique.

Rickettsia tsutsugamushi organisms were identified in Giemsa and fluorescent antibody stained monocyte cell cultures derived from experimentally infected monkeys and dogs. The identification of organisms in monocyte cell cultures compared favorably with the standard technique of mouse inoculation.
