Abstract
Background: Spontaneous hemorrhage is a rare but serious complication of dermatomyositis (DM).
Methods: We report a 61-year-old man with anti-NXP2-positive DM who developed a retroperitoneal hematoma without anticoagulation, shortly after corticosteroid initiation.
Results: Laboratory investigations demonstrated rhabdomyolysis, hepatic injury and coagulopathy. The patient was managed with red blood cell transfusion, factor VIII, high-dose corticosteroids and intravenous immunoglobulin, resulting in complete recovery.
Conclusions: Although hemorrhagic events in DM are most often linked to anti-MDA5 or anti-Ro52 antibodies, their association with anti-NXP2 antibodies remains uncertain. This case highlights the importance of early recognition and prompt intervention in managing spontaneous hemorrhage in DM.

Clinical Laboratory is an international fully peer-reviewed journal covering all aspects of laboratory medicine and transfusion medicine. In addition to transfusion medicine topics Clinical Laboratory represents submissions concerning tissue transplantation and hematopoietic, cellular and gene therapies. The journal publishes original articles, review articles, posters, short reports, case studies and letters to the editor dealing with 1) the scientific background, implementation and diagnostic significance of laboratory methods employed in hospitals, blood banks and physicians'' offices and with 2) scientific, administrative and clinical aspects of transfusion medicine and 3) in addition to transfusion medicine topics Clinical Laboratory represents submissions concerning tissue transplantation and hematopoietic, cellular and gene therapies.
