Tenofovir, a nucleotide reverse transcriptase inhibitor, rarely causes skin issues. This report details a rare case of tenofovir-induced lichenoid drug eruption in an HIV patient, resolving after drug discontinuation.
Area of Science:
- Dermatology
- Infectious Diseases
- Pharmacology
Background:
- Cutaneous adverse reactions are frequent in anti-retroviral therapy.
- Tenofovir, a nucleotide reverse transcriptase inhibitor, commonly causes systemic side effects but rarely cutaneous reactions.
- Lichenoid drug eruptions are a known adverse effect of various medications.
Observation:
- A 54-year-old human immunodeficiency virus (HIV) positive male developed a generalized lichenoid eruption.
- The eruption appeared six weeks after initiating tenofovir therapy.
- Skin symptoms resolved completely upon discontinuing tenofovir.
Findings:
- This case highlights a rare instance of tenofovir-induced lichenoid drug eruption.
- Only one prior case of this specific adverse reaction to tenofovir has been documented.
- The clinical presentation and resolution pattern strongly suggest a causal link between tenofovir and the eruption.
Implications:
- Clinicians should consider tenofovir as a potential cause of lichenoid drug eruptions in HIV patients.
- Early recognition and drug cessation can lead to complete resolution of this rare cutaneous adverse effect.
- Further pharmacovigilance is needed to fully understand the cutaneous safety profile of tenofovir.
