Whitish papules on the palm

Watersport hands

Aquagenic syringeal acrokeratoderma is a newly described condition of the palms and soles characterized by hypopigmented papules and plaques, elicited after submersion in water. Symptoms include a burning pain and a tightening sensation in the palms, as well as hyperhidrosis. Initially thought to be rare, its frequent citation in the literature points to a more common entity. It is more often found in young women and has been linked to a number of medications and illnesses, including nonsteroidal anti-inflammatory drugs and cystic fibrosis. It is typically self-limiting, but certain medications such as topical aluminum chloride or salicylic acid ointment have been found to be an effective treatment option. This case details a collegiate-level coxswain who presented to the university athletic training room with a typical presentation of aquagenic syringeal acrokeratoderma. For an aquatic athlete, aquagenic syringeal acrokeratoderma can be a distressing condition that can limit training and athletic participation. As such, the sports medicine physician should be knowledgeable about aquagenic syringeal acrokeratoderma to provide effective counseling and treatment options for the athlete.

Aquagenic keratoderma. Two new case reports and a new hypothesis

Aquagenic keratoderma has been described as a transient condition affecting predominantly young females and defined clinically by the appearance of palmar hyper-wrinkling accentuated after immersion in water. We present two new cases with aquagenic palmoplantar acrokeratoderma - a child and a young male. A significant clinical improvement was achieved after topical treatment with aluminum salts. Aquagenic palmar keratoderma may be a clue to cystic fibrosis in adolescents and young adults. We developed a new hypothesis on its pathogenesis.

Unilateral aquagenic keratoderma treated with botulinum toxin A

BACKGROUND

Aquagenic keratoderma is a rare transient disease that occurs after water immersion and disappears shortly after drying. Most cases involve the palms and fingers bilaterally but it can also affect the soles. Few cases have been associated with drugs but its pathogenesis remains unclear.

MAIN OBSERVATION

We report a 60-year-old man with a 30-year-history of aquagenic keratoderma of the right palm without associated hyperhidrosis or history of drug intake. After unsuccessful treatment with 15% aluminium chloride hexahydrate gel, botulinum toxin A injections led to significant improvement within 2 weeks.

CONCLUSIONS

To our knowledge, this case is the first report of idiopathic unilateral aquagenic keratoderma in the medical literature. It is the third report of successful treatment with botulinum toxin A which is in favor of a role of sweat glands in the pathogenesis of aquagenic keratoderma.
