We describe the first occurrence of Swine Hemorrhagic Syndrome (SHS) in Paraná State, Brazil. Forty seven pigs, raised in an intensive production system farm were affected by SHS dying within 24 to 72 hours of starting the clinical signs. All animals presented progressive joint swollen with hemorrhagic skin and oro-nasal bleeding. Hemorrhagic lesions, located on subcutaneous and muscular tissues, were observed at post morten examination. The capillary tube test demonstrated coagulation abnormalities with absence of clotting formation. Clinical signs, anatomophatological lesions as well as epidemiological informations, and laboratory findings suggested the diagnose of SHS. The diagnostic was confirmed by response to terapy and absence of new cases after Vitamin K supplementation.
