Relating to the study of the microscopic structure of tissues and cells in disease.
The histopathologic examination revealed significant changes in the tissue samples.
Histopathologic → It is formed from "histo-" (from Greek "histos", meaning tissue) and "pathologic" (from Greek "pathos", meaning suffering or disease, and "logia", meaning study). The word refers to the study of tissue changes caused by disease.
Think of 'tissue' ('histo-') being studied for 'disease' ('pathologic') — that's what histopathologic means.
