Abstract Background Antiphospholipid Syndrome (APS) is a multisystemic autoimmune disease characterized by arterial and venous thrombosis and / or obstetric morbidity in the presence of at least one circulating anti-phospholipid antibody. The spectrum of vascular events varies from deep venous thrombosis to catastrophic APS, a rare form characterized by acute multiorgan thrombosis and high mortality. Case report We present the case of a 32-week pregnant woman arriving in the hospital emergency room with bilateral acute lower limb ischemia. In the obstetric evaluation, fetal death was declared. Computerized Tomography angiography showed pulmonary embolism of both pulmonary arteries, areas of splenic and right renal infarction and multiple arterial and venous thrombosis. The patient underwent urgent caesarean section and axillary-bifemoral bypass. No events registered. In the postoperative period, in an intensive care unit, treatment with rituximab and plasmapheresis were added to anticoagulant therapy. The laboratorial investigation was negative for thrombophilia and autoimmune diseases. Conclusion Catastrophic APS develops quickly, with multiorgan involvement and high mortality rate. The presented case poses a multidisciplinary challenge, with the surgical approach of extra-anatomical revascularization being less invasive and guaranteeing immediate perfusion of the lower limbs. Although the serological tests were negative for anti-phospholipid antibodies, this case hardly fits into another diagnosis. Therefore, it was treated as a catastrophic APS, having shown a favorable evolution.

COVID-19 is the clinical expression of the highly contagious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral infection. Most patients have mild symptoms, but a significant proportion have severe or critical disease, which can include cardiac injury, sepsis, acute kidney failure and respiratory failure. It is also worth highlighting the increasing number of reported COVID-19 cases with dermatological disease/manifestations. The cutaneous clinical spectrum is wide and includes maculopapular, urticarial, varicelliform and petechial rashes, pseudo perniosis, livedo reticularis, and pityriasis rosea-like, violaceous and pustular lesions. Until the physiological mechanism is fully understood, it is important to describe these manifestations, which could help identify a typical pattern. This report describes a cutaneous manifestation in a COVID-19 patient.
