RESUMO

ABSTRACT CONTEXT: Various skin manifestations have been reported in coronavirus disease. It may be difficult to determine the etiology of these lesions in view of the increased frequency of handwashing during the pandemic, along with occurrences of irritant contact dermatitis and allergic contact dermatitis due to disinfectant use; usage of herbal medicine and supplements to strengthen the immune system; and urticarial or maculopapular drug eruptions due to COVID-19 treatment. The variety of associated skin manifestations seen with COVID-19 makes it challenging to identify virus-specific skin manifestations. Petechiae, purpura, acrocyanosis and necrotic and non-necrotic purpura, which can be considered as manifestations of vascular involvement on the skin, have been reported. CASE REPORT: Here, we report a case of eruptive cherry angiomas, which was thought to have developed due to COVID-19, with a papulovesicular rash on distal extremities that progressed over time to reticular purpura. CONCLUSION: The case presented had a papulovesicular rash at the onset, which evolved to retiform purpura, and eruptive cherry angiomas were observed. It should be kept in mind that dermatological signs may vary in patients with COVID-19.

RESUMO

Las manifestaciones cutáneas en las enfermedades autoinmunes son frecuentes y heterogéneas. En algunas de ellas, como en el caso del lupus eritematoso sistémico, la dermatomiositis, la esclerosis sistémica y el síndrome antifosfolípidico son de tal importancia que se incluyen como criterios clasificatorios de la enfermedad. Los diagnósticos diferenciales varían en gravedad, pudiendo en ocasiones presentar riesgo vital, por lo cual se jerarquizan el diagnóstico y tratamiento oportunos. Se describe el caso de una paciente de 22 años con diagnóstico previo de lupus eritematoso sistémico y síndrome antifosfolípídico, que concurre a la consulta con cuadro agudo caracterizado por lesiones cutáneas dolorosas de aspecto necrótico acompañadas de fiebre y livedo reticularis.


Cutaneous involvement is frequent and heterogeneous in autoimmune diseases. In some of them, such as in systemic lupus erythematosus, dermatomyositis, systemic sclerosis and antiphospholipid syndrome, some manifestations are so relevant that are included in the classification criteria. Differential diagnosis ranges in severity. Since the disease may be life-threatening, a prompt diagnosis and treatment are mandatory. We describe a clinical case of a twenty-two-year-old woman with diagnosis of systemic lupus erythematosus and antiphospholipidic syndrome, presenting with acute, painful cutaneous lesions with necrotic aspect, fever and livedo reticularis.

RESUMO

Levamisole has been increasingly used as an adulterant of cocaine in recent years, emerging as a public health challenge worldwide. Levamisole-associated toxicity manifests clinically as a systemic vasculitis, consisting of cutaneous, hematological, and renal lesions, among others. Purpura retiform, cutaneous necrosis, intravascular thrombosis, neutropenia, and less commonly crescentic nephritis have been described in association with anti-neutrophil cytoplasmic antibodies (ANCAs) and other autoantibodies. Here we report the case of a 49-year-old male who was a chronic cocaine user, and who presented spontaneous weight loss, arthralgia, and 3 weeks before admission purpuric skin lesions in the earlobes and in the anterior thighs. His laboratory tests on admission showed serum creatinine of 4.56 mg/dL, white blood count 3,800/μL, hemoglobin 7.3 g/dL, urinalysis with 51 white blood cells/μL and 960 red blood cells/μL, and urine protein-to-creatinine ratio 1.20. Serum ANCA testing was positive (>1:320), as well as serum anti-myeloperoxidase and anti-proteinase 3 antibodies. Urine toxicology screen was positive for cocaine and levamisole, with 62.8% of cocaine, 32.2% of levamisole, and 5% of an unidentified substance. Skin and renal biopsies were diagnostic for leukocytoclastic vasculitis and pauci-immune crescentic glomerulonephritis, respectively. The patient showed a good clinical response to cocaine abstinence, and use of corticosteroids and intravenous cyclophosphamide. Last serum creatinine was 1.97 mg/dL, white blood cell count 7,420/μL, and hemoglobin level 10.8 g/dL. In levamisole-induced systemic vasculitis, the early institution of cocaine abstinence, concomitant with the use of immunosuppressive drugs in severe cases, may prevent permanent end organ damage and associate with better clinical outcomes.
