Area of Science:

  • Hepatology
  • Clinical Toxicology
  • Immunology

Background:

  • Diphenylhydantoin (phenytoin) is an anticonvulsant medication with known potential for idiosyncratic drug reactions.
  • Drug-induced liver injury (DILI) is a significant concern in clinical practice, necessitating accurate diagnostic approaches.
  • This case highlights a severe presentation of diphenylhydantoin-induced hepatitis.

Observation:

  • A 25-year-old male presented with symptoms including fever, rash, and generalized lymphadenopathy.
  • Clinical presentation was suggestive of a severe adverse drug reaction.
  • Hepatic histology and lymphocyte transformation tests were crucial in establishing the diagnosis.

Findings:

  • The patient was diagnosed with severe diphenylhydantoin-induced hepatitis.

  • Histopathological examination of the liver confirmed hepatocellular damage.
  • Lymphocyte transformation tests indicated an immune-mediated response to diphenylhydantoin.

    • Implications:

    • This case underscores the importance of considering drug-induced hepatitis in patients presenting with unexplained liver injury and systemic symptoms.
    • Early recognition and withdrawal of the offending agent are critical for favorable outcomes in diphenylhydantoin-induced hepatitis.
    • Supportive management is effective in facilitating recovery from severe drug-induced liver injury.
