[Aquagenic urticaria. A case report].

Aquagenic urticaria remains a poorly understood skin condition. It is a rare form of contact urticaria triggered by water exposure. Prior research has shown that this condition primarily affects the upper body with small wheals. It is distinct from aquagenic pruritus, which lacks visible skin lesions. Little is known about the underlying mechanisms. No definitive cause has been identified. This gap motivated further investigation into clinical presentation and management strategies. That uncertainty drove the need for case reports to better characterize the condition.

This case report aimed to describe a patient with aquagenic urticaria. The specific problem was to document clinical features and treatment responses. The motivation was to contribute to the limited literature on this condition. No prior work had resolved the diagnostic criteria in detail. The goal was to confirm the diagnosis through clinical evaluation. The study also sought to explore potential therapeutic options. No prior work had evaluated the effectiveness of hydrophobic barrier creams in this context. This approach allowed for a detailed clinical description.

The study involved a single patient presenting with urticaria after water contact. Clinical evaluation confirmed the diagnosis of aquagenic urticaria. The patient's symptoms were assessed through physical examination. No specialized tools were used beyond standard dermatological evaluation. The condition was differentiated from aquagenic pruritus. Treatment options were discussed with the patient. Antihistamines, ultraviolet therapy, and hydrophobic creams were considered. The patient's response to these interventions was monitored.

The patient experienced recurrent urticaria episodes after water exposure. Symptoms were localized to the upper body with small wheals. No systemic symptoms were reported. The diagnosis was confirmed through clinical evaluation. Antihistamines provided partial relief. Ultraviolet therapy was also considered as a treatment option. Application of hydrophobic barrier creams showed some effectiveness. No definitive treatment was identified as universally effective.

The authors concluded that aquagenic urticaria is a rare and poorly understood condition. Clinical evaluation remains the primary diagnostic method. Differentiation from aquagenic pruritus is essential. Treatment options include antihistamines and barrier creams. No single treatment was found to be consistently effective. The condition requires individualized management strategies. Further research is needed to clarify pathogenic mechanisms. These findings suggest a need for more detailed clinical studies.
