An Unusual Symmetrical Fixed Drug Eruption

Area of Science:

• Dermatology
• Clinical Case Reports
• Adverse Drug Reactions

Background:

• Fixed drug eruption (FDE) is an idiosyncratic cutaneous reaction to a medication, typically presenting with recurrent, well-demarcated erythematous to violaceous plaques at specific sites upon re-exposure.
• Commonly affected sites include the genitalia, trunk, and limbs, but symmetrical distribution on the hands and feet is infrequent.

Observation:

• This report details an unusual case of fixed drug eruption in a patient exhibiting a distinct symmetrical distribution of lesions on both hands and feet.
• The lesions appeared consistently on these symmetrical locations following exposure to the causative agent.

Findings:

• The symmetrical presentation on the hands and feet represents an atypical pattern for fixed drug eruption.
• Diagnostic confirmation was based on clinical presentation and patient history of recurrent lesions at these specific sites after drug intake.

Implications:

• This case expands the spectrum of clinical manifestations of fixed drug eruption.
• Awareness of such unusual distributions is crucial for timely diagnosis and appropriate management of fixed drug eruption, preventing further adverse reactions.
