Drug toxicity, also drug reaction, in pathology is often a diagnosis of exclusion. Few drugs leave a distinctive histomorphologic pattern.

This article covers a few of the distinctive histomorphologic pattern and links to other articles that deal with specific organ systems.

    • Improvement with removal of exposure.
    • Pathologic pattern matches with toxin.
    • Drug.
