I. To identify dose-limiting toxicities (DLT). II. To perform skin and tumor biopsies to analyze molecular inhibition of the epidermal growth factor receptor (EGFR) signaling pathway, defined as a >= 75% inhibition of phosphorylation of the epidermal growth factor (EGF) receptor or of its downstream effectors tumor protein (p)44/42 mitogen-activated protein kinase (MAPK) or protein kinase B (Akt) or as a >= 25% decrease of marker of proliferation Ki-67 (Ki67) from baseline in either skin or tumor tissue in the majority of patients.
