pathologicpathological

Pathologicpathological is not an established term in medical or general English usage. It appears to be a concatenation of two related adjectives, pathologic and pathological, which share a common root related to disease but are used with subtle distinctions.

Pathologic is the spelling favored in American English in many medical contexts. It describes things pertaining to disease, the processes of disease, or tissue changes studied by pathology. In practice, pathologic findings, pathologic analysis, and pathologic fracture are common phrases in medical reporting, radiology, and histology.

Pathological is the spelling preferred in British English and is widely used elsewhere. It is a general adjective meaning relating to pathology or disease, and in non-medical contexts it can describe excessive or abnormal behavior, as in pathological jealousy or a pathological liar. In medical writing, pathological is often used more broadly to denote disease-related considerations, though both spellings are understood in professional contexts.

Etymology: both pathologic and pathological derive from Greek pathos, meaning suffering, and -logia, meaning study. Together they form terms connected to the science of disease, pathology.

In writing, choose one spelling consistent with the style guide you follow. In American medical literature, pathologic and its variants appear frequently; in British and many international contexts, pathological is more common. The combined form pathologicpathological is not recognized as a distinct concept.
