Acute promyelocytic leukemia (APL) is a type of acute leukemia showing unique clinical, morphological and cytogenetic features. A skin infiltration by APL cells is an extremely rare occasion, but there have been several case reports of leukemia cutis in APL, in which all-trans retinoic acid (ATRA) may have induced the skin infiltration. However, no immunohistochemical analyses of the APL cells in the skin have been done to date. A 30-year-old woman with APL developed multiple reddish purple nodules on the extremities in her second complete remission. Histological findings revealed a dense infiltration of medium to large atypical cells, which were positive for myeloperoxidase, throughout the dermis. Despite the conventional chemotherapy and ATRA therapy she died from disseminated intravascular coagulation during her third relapse. Leukemic cells in the peripheral blood before the treatment with ATRA revealed CD3-/CD4-/CD5-/CD7-/CD8-/CD10-/CD13++/CD14-/CD19 -/ CD20-/CD33++/CD38++/CD41-/Ia-, but they expressed CD3-/CD4-/CD5-/CD7++/ CD8-/CD10-/CD13++/CD14-/CD19-/CD20-/CD33++ /CD38++/CD41+/Ia+ after the treatment. We suggest that the alternation of the surface molecules on the tumor cells is closely associated with the skin infiltration of APL cells.

An 82-year-old woman was admitted with fever and anorexia. Aggravated pancytopenia and liver dysfunction suggested the presence of disseminated intravascular coagulation. The serum ferritin level increased to 9,100 ng/ml. Bone marrow aspiration showed an increase of histiocytes with phagocytosis and a diagnosis of hemophagocytic syndrome was made. Symptomatic therapy was performed because of her deteriorated general condition. She died of multiple organ failure, 32 days after admission. Autopsy revealed swollen lymph nodes with proliferation of large neoplastic cells containing rich cytoplasm and pleomorphic and multi-segmented large nuclei. The immunophenotype of the neoplastic cells was LCA-, CD3-, CD5-, CD 20-, CD79a-, UCHL1-, MT1-, CD15-, p80-. Neoplastic cells were positive for CD30, mainly in Golgi apparati, and also positive for EBV-encoded small nonpolyadenylated RNAs (EBER). This case was diagnosed as anaplastic large cell lymphoma (ALCL) associated with hemophagocytic syndrome. It was estimated that Epstein-Barr virus had played an important role in the development of ALCL in the present case.
