Shwachman syndrome: a case report.

Cutaneous involvement is frequent in Shwachman syndrome, and includes various degrees of dry skin, and eczematous and ichthyosiform lesions. A 12-year-old boy with Shwachman syndrome had cutaneous involvement characterized by dry skin, perioral dermatitis, and follicular keratosis. Polymorphonuclear motility was decreased. A nutrition work-up showed a decrease in liposoluble vitamins, and suggested a causative link with the skin lesions.
