Keratosis pilaris in pregnancy: an unrecognized dematosis of pregnancy?

Keratosis pilaris (KP) is a common hyperkeratotic condition that most commonly presents as skin-colored follicular papules surrounded by erythema. These lesions often appear grouped together on the lateral aspect of the arms, thighs, and buttocks. Although the etiology of KP is uncertain, it is thought to be the result of the formation of an orthokeratotic plug, which blocks and dilates the orifice and upper portion of the follicular infundibulum (Figure 1). Histologically, mild perivascular mononuclear cell infiltrates are usually present in the adjacent dermis. Studies have indicated a role for hormonal influences in the development of KP. The five cases presented in this study demonstrate keratosis pilaris as a condition in which the onset or severity of the dermatosis may be linked to the hormonal changes of pregnancy.
