Diagnostic terminology is that used by pathologists, physicians who diagnose human disease by examination of histologic preparations of excised tissues.

Alternatively, it is possible that newer processing methods can be applied to testis FNA cytology specimens to concentrate and prepare seminiferous tubules for sectioning similar to classic histologic preparations.

A researcher was employed and an electron microscopic technique was then devised which confirmed the suspicion that human papillomavirus (HPV) particles were present in these abnormal cells, in both cytologic and histologic preparations (Pap smears and cervical biopsies).

An office endometrial sampling, or a dilatation and curettage (D&C), is then performed, providing a histologic specimen for diagnosis.

Histologic specimens for the diagnosis of IPF must be large enough that the pathologist can comment on the underlying lung architecture.

Therefore, it is important to assess the positive predictive value of both markers, MCM2 and Ki-67, for lung cancer risk in cytologic and histologic specimens from a defined population at risk for this disease in a prospective study.
