title: Orbital phycomycosis.
abstract: 3 cases with rhinoorbital phycomycosis and a 4th case, in which it was considered retrospectively, are presented in hematological patients. 2 of the 4 patients survived. In the first 3 cases, which appeared in a period of 2 months in the Hematology Unit, an epidemiological study was made, showing that the cause of the infections was contamination of the air-conditioning systems of this unit by numerous Phycomycetes and Mucor pusillus.
