Primary Antiphospholipid Syndrome: An Unusual Presentation Síndrome Antifosfolipídica Primária: Uma Apresentação Incomum

Abstract

The antiphospholipid syndrome is characterized by thrombotic events, recurrent fetal death and the presence of circulating antiphospholipid antibodies.
We report an interesting case of a male patient who presented with recent constitutional and gastrointestinal symptoms raising a suspicion of intestinal sub-occlusion or even a neoplastic process.
During the investigation, other potential etiologies were excluded, and thrombi were identified in the right ventricle and abdominal aortic, as well as laboratory alterations suggestive of antiphospholipid syndrome.
In this particular case, uncommon location of the thrombi as well as the lack of specificity of the symptoms made it difficult and delayed the diagnosis and the implementation of treatment.
