Hypercaroténémie chez un nourrisson

Although pruritus has never been reported in isolated hypercarotenaemia it is a classical sign of hypervitaminosis A. The mechanism of pruritus is not understood in this instance since vitamin A levels were normal. This case report is also unusual in that no classical cause of hypercarotenaemia was found, as a result of which we concluded on a likely defect in beta-carotene 15, 15'oxygenase, an enzyme involved in vitamin A production.
