Abstract: A composition is described comprising a vitamin D analog and a retinoid wherein: (a) the vitamin D analog is capable of binding a vitamin D receptor or being converted in vivo into a compound capable of binding a vitamin D receptor; and (b) the retinoid is selected from the group consisting of retinol in a concentration of at least about 1.0%, a compound in a concentration of at least about 1.0% capable of being converted in vivo into retinol, and a retinoid characterized by having a substitution at the 4-position. Further, methods of treating disorders characterized by abnormal cell-proliferation and/or cell-differentiation are also described.
