BACKGROUND: Ofuji's disease is an eosinophilic dermatosis mostly affecting male subjects. It is characterized by the appearance of follicular papulopustolosis, at times on an erythematous base, which tend to form an annular configuration. PATIENTS AND METHODS: Two cases are described: the first is a 45-year-old man affected by acute myeloid leukaemia and Ofuji's disease; the second is a 61-year-old man affected by chronic lymphatic leukaemia and Ofuji's disease. Culture tests were negative in both cases. In both patients no hypereosinophilia was found. CONCLUSIONS: The simultaneous presence of the two pathologies in these patients can only give rise to hypothesis. In the first case it could be attributed to interleukin (IL)-5, which causes both eosinophilic hyperproduction and blast differentiation. In the second case the hypersecretion of intercellular adhesion molecule type 1 (ICAM-1) in Ofuji's disease could be attributed to a modified transcriptional gene belonging to the class of immunoglobulin codifying genes located on the altered chromosomes in a certain percentage of leukaemic patients.
