title: Tretinoin-induced sticky skin: a case report and review of the literature.
abstract: Sticky skin has been reported relatively infrequently in the literature in association with etretinate and doxorubicin/ketoconazole administration. It has a poorly understood pathogenesis, and the associated histologic changes have not been described. We report a case of a patient who experienced sticky skin in areas treated with tretinoin. These reverted to normal after cessation of treatment. In comparison to a biopsy taken while the skin was not sticky, the histologic findings included a thickened, compact stratum corneum and granulosum. The basal epithelial cells showed proliferation with slight crowding and a tall, columnar shape. To our knowledge, this is the first report of sticky skin occurring in response to topical retinoid application. We suggest that the histologic changes observed could represent a modified keratin maturation profile.
