Recurrent Bilateral Lime Disease in a Young Female- Case Report.

Abstract

Introduction: Lime phytodermatitis, also known as margarita dermatitis, is a condition that results in a skin rash after sunlight exposure when handling certain plants. Misdiagnosis is common due to its resemblance to skin burns or allergic contact dermatitis. Detailed history and disease recognition is important to provide accurate treatment recommendations.

Case report: A 32-year-old woman presented with a recurrent rash on her hands that would only occur in the summer months. She was previously misdiagnosed as allergic contact dermatitis. History revealed yearly vacations involving margaritas and squeezing lime into her drinks followed by exposure to sunlight. A presumptive diagnosis of lime phytodermatitis was made and she was advised to avoid contact with limes followed by exposure to direct sunlight.

Discussion: Lime phytodermatitis occurs after direct contact with lime and sunlight exposure. A phototoxic compound found in limes, Furocoumarin, has been implicated as a cause for lime disease. Detailed history is important in establishing a diagnosis of lime disease. Treatment is symptomatic with topical corticosteroids, avoidance of furocoumarin-containing objects, cold compresses, and subsequent UV exposure.

Conclusion: We present the first case of recurrent, bilateral phytodermatitis in a 32-year-old woman following contact with limes and subsequent sunlight exposure in the summer months.
