Pyrimethamine treats toxoplasmosis and malaria but can cause rare skin hyperpigmentation. This report details a case of hyperpigmentation in an HIV-negative patient using pyrimethamine.

Area of Science:

  • Pharmacology
  • Dermatology
  • Infectious Diseases

Background:

  • Pyrimethamine is a key medication for treating toxoplasmosis and preventing malaria.
  • Common side effects include blood disorders and gastrointestinal issues.
  • Skin hyperpigmentation is an exceptionally rare adverse effect.

Observation:

  • This study focuses on an HIV-negative individual.
  • The patient developed hyperpigmentation during pyrimethamine treatment.

Findings:

  • The case highlights hyperpigmentation as a potential, albeit rare, side effect of pyrimethamine.
  • This adverse reaction was observed in an HIV-negative context, differentiating it from co-infection complexities.

Implications:

Related Experiment Videos

  • Clinicians should consider skin hyperpigmentation in patients on pyrimethamine, even without HIV.
  • This case expands the known spectrum of pyrimethamine's dermatological side effects.
  • Further research may be needed to understand the mechanism of pyrimethamine-induced hyperpigmentation.
