Aquatic/aquagenic Dermatoses: The Thin Line Between Pool Palms and Aquagenic Syringeal Acrokeratoderma

Pool palms and pool toes are friction or pressure-induced aquatic dermatoses resulting from extensive and repetitive rubbing of fingers, palms, soles, and toes against the rough anti-slippery surfaces or edges of pools. Aquagenic syringeal acrokeratoderma is a sporadic, episodic, and acquired disorder of palmar skin linked to water exposure. Herein we describe a case of aquatic/aquagenic dermatosis that presented clinical and diagnostic difficulties. Differentiating between pool palms and aquagenic syringeal acrokeratoderma is a challenge, and we believe that both disorders lie on a spectrum of watersport dermatoses.
