Fig 1 Clinical and morphologic aspects of the disease. A, Red-brown, pityriasis versicolor–like lesions on the trunk and arms. B, Merkel cell carcinoma. A pink-red nodule on the trunk. C, Immunolabeling for chromogranin shows dot-like cytoplasmic reactivity within tumor cells.

Fig 2 Detection of Merkel cell polyomavirus (MCV) DNA using polymerase chain reaction (PCR) in a Brazilian patient with Merkel cell carcinoma (MCC). The PCR primers were minor modifications of the primer set LT3 (formerly described by Feng et al).3 PCR products were analyzed on 2.0% agarose gel electrophoresis and visualized on an ultraviolet transilluminator. A, Lane M shows the fX174RF DNA marker (Promega Co); lane 1 shows MCC; lane 2 shows MCV-negative control DNA extracted from peripheral blood mononuclear cells (Promega Co); and lane 3 shows the reagent control. The expected 309bp PCR product of MCV can be seen in lane 1. B, Beta-globin reference gene PCR assays. Lane M shows the fX174RF DNA marker; lane 1 shows MCC; lane 2 shows the MCV-negative control DNA extracted from peripheral blood mononuclear cells (Promega Co); and lane 3 shows the reagent control. The expected beta-globin 268bp PCR fragments can be seen in lanes 1 and 2. Journal of the American Academy of Dermatology , DOI: ( /j.jaad ) Copyright © 2009 American Academy of Dermatology, Inc.
