The mucocutaneous manifestations associated with celiac disease in childhood and adolescence.

This study was performed to detect the prevalence of mucocutaneous manifestations of celiac disease in childhood and adolescence and to investigate the relationship between these findings and duration of disease and a gluten-free diet. The study included 55 children and adolescents with a mean age of 10.0 +/- 4.61 years (2-19 years). Mucocutaneous manifestations were evaluated with respect to age, gender, duration of illness, and of gluten-free diet and compliance with this diet. Cutaneous, mucosal, nail, and hair findings were detected in 74.5%, 27.3%, 20.0%, and 7.3% of patients, respectively. The most prevalent dermatologic diagnosis was xerosis (69.1%). No significant relationship was detected between the cutaneous findings and the duration of illness (p > 0.05). However, the duration was longer in patients with mucosal findings compared to those without mucosal findings (p < 0.05). It was found that all patients without cutaneous findings were on a strict gluten-free diet (p < 0.05). Ours is one of the few studies describing skin findings in children with celiac disease. We believe that both pediatricians and dermatologists should be aware of the various mucocutaneous manifestations of celiac disease, because a careful skin, mucosa, nail, and hair examination may lead to a diagnosis of celiac disease, particularly in atypical presentations.
