Acta Dermato-Venereologica
|January 1, 1978
Summary
A fixed drug eruption developed in a woman after a year of tetracycline treatment for pharyngitis. Patch testing confirmed the tetracycline drug eruption diagnosis.
Area of Science:
- Dermatology
- Pharmacology
Background:
- Fixed drug eruptions are a type of adverse drug reaction.
- Tetracycline is a broad-spectrum antibiotic commonly used for various infections.
Observation:
- A 29-year-old woman presented with a pulsating, fixed drug eruption.
- The eruption occurred after one year of continuous oral and parenteral tetracycline therapy for pharyngitis.
Findings:
- Patch testing with tetracycline powder under occlusion at the eruption site confirmed the diagnosis.
- This case highlights a delayed hypersensitivity reaction to tetracycline.
Implications:
- Clinicians should consider fixed drug eruptions in patients on long-term tetracycline therapy.
- Accurate diagnosis through patch testing is crucial for managing antibiotic-induced skin reactions.
