Acquired aquagenic syringeal acrokeratoderma: A case series of 10 patients

Acquired Aquagenic Syringeal Keratoderma Following COVID-19 Infection

Aquagenic syringeal keratoderma (ASK), rare in males, is characterized by the rapid onset of edematous palmar wrinkling with small white papules after brief contact with water or sweat. A 24-year-old atopic male presented with a 2-week subacute history of bilateral palmar edema with whitish-colored papules after exposure to water, 3 months after having had COVID-19 infection treated with a full course of ritonavir-boosted nirmatrelvir (PAXLOVIDTM). He had received 3 COVID-19 vaccines (Pfizer, New York, NY) about 12 months prior. Workup was negative. Initial spontaneous near-resolution 2 months after onset was temporary, with recurrence 1 month later. Treatment with 12% topical aluminum chloride was ineffective. Botulinum toxin injection to both palms led to resolution of symptoms that has been sustained for 7 months. The association between atopy and ASK remains weak. We present a case of new-onset ASK in an adult male 3 months following COVID-19 infection without a history of excessive handwashing. Our patient may have had a predisposition to recurrent ASK due to his history of atopy including atopic dermatitis and food allergy anaphylaxis combined with prior COVID-19 infection. It is possible that ASK is a novel manifestation of post-acute sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (PASC) infection or long COVID.

Dermatosis inducida por el agua: queratodermia acuagénica, a propósito de un caso

La queratodermia acuagénica es una entidad benigna, caracterizada por producir pápulas blanquecinas o traslúcidas pocos segundos después del contacto con el agua.Se presenta el caso de una paciente de 16 años de edad con aparición de múltiples pápulas confluentes y asintomáticas en ambas palmas al contacto con el agua, que desaparecían luego del secado. En el estudio de histopatología se observó dilatación de los conductos ecrinos y cambios en el estrato córneo.Esta rara condición de etiología desconocida se ha relacionado con disfunción neuronal, alteraciones de las glándulas ecrinas y, más recientemente, con alteraciones en las acuaporinas. Se puede diagnosticar con una prueba semiológica sencilla llamada ‘la mano en el balde’; la sospecha clínica es fundamental para hacer el diagnóstico, ya que los hallazgos histopatológicos pueden ser sutiles e inespecíficos. El tratamiento tópico incluye mecanismos de barrera y la toxina botulínica.

Water-related dermatoses

Water-related dermatoses are a spectrum of diseases that are associated with water exposure. They result either from the direct influence of water or after injury from water inhabitants. In this review, clinical entities that manifest after water exposure (aquagenic pruritus, aquagenic urticaria, and aquagenic wrinkling of the palms) will be discussed with particular focus on the reported pathogenesis. Aquatic organisms and activities can be linked to cutaneous injuries that require identification and distinct management. Marine and freshwater dermatoses were summarized to provide physicians with easy access to the causative organism, method of injury, and appropriate management.

The first Danish family reported with an AQP5 mutation presenting diffuse non-epidermolytic palmoplantar keratoderma of Bothnian type, hyperhidrosis and frequent Corynebacterium infections: a case report

Background

An autosomal dominant form of diffuse non-epidermolytic palmoplantar keratoderma, palmoplantar keratoderma of Bothnian type, is caused by mutations in the AQP5 gene encoding the cell-membrane water channel protein aquaporin 5 leading to defective epidermal-water-barrier function in the epidermis of the palms and soles.

Case presentation

We report the first Danish family diagnosed with diffuse non-epidermolytic palmoplantar keratoderma of Bothnian type in which fourteen individuals are potentially affected. The proband, a 36-year-old male had since childhood been affected by pronounced hyperhidrosis of the palms and soles along with palmoplantar keratoderma. He reported a very distinctive feature of the disorder, aquagenic wrinkling, as he developed pronounced maceration of the skin with translucent white papules and a spongy appearance following exposure to water. The patient presented recurrent fungal infections, a wellknown feature of the condition, but also periodic worsening with pitted keratolysis and malodour due to bacterial infections.

Conclusions

Palmoplantar keratoderma of Bothnian type, which may be associated with hyperhidrosis, is frequently complicated by fungal infections and may be complicated by Corynebacterium infections.

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.
