[Celecoxib-induced aquagenic keratoderma].
Aquagenic keratoderma is an infrequent condition characterized by translucent, smooth-surfaced papules and plaques and prominent eccrine ducts. It is limited to the palms and appears or becomes more pronounced after exposure to water. Histopathologically, hyperkeratosis and dilation of the eccrine ducts are seen. This condition has been described in adolescents and young women. We present the case of a 31-year-old woman with rheumatoid arthritis who had begun treatment with celecoxib one month before the onset of her cutaneous symptoms. Similar changes have been described in association with cystic fibrosis, and a case induced by rofecoxib has also been reported. Higher levels of sodium in the skin associated with celecoxib could increase the keratin's ability to take in water, and this may cause the clinical symptoms.
