title: A case of cutaneous Ki-1 positive anaplastic large cell lymphoma in a hemodialysed patient.
abstract: A 66-year-old woman who suffered from chronic glomerulonephritis had been undergoing hemodialysis for about 10 years. A reddish papule on her waist developed gradually into a nodule (1.9 x 1.4 cm). Histopathological findings showed that the tumor cells had oval to reniform nuclei; multinucleated neoplastic cells and erythrophagocytosis were also present. Immunohistochemical analyses revealed that the membranes of the tumor cells stained for Ber-H2 (Ki-1) and epithelial membrane antigen (EMA), Vimentin was partially positive, but keratin, S-100, chromogranin, leukocyte common antigen (LCA), UCHL-1, MT-1, L-26, MB-1 and C3D-1 were all negative. Anti-human T-cell leukemia virus-1 (HTLV-1) was also negative. No gene rearrangement of the T-cell receptors beta-, gamma- and delta-chain could be detected. From these results, we diagnosed cutaneous Ki-1 anaplastic large cell lymphoma (ALCL), but the origin could not be determined. The relationship between lymphoma and chronic renal failure and/or hemodialysis was far from clear.
