A pandemic coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), causes a disease called COVID-19, which is potentially life-threatening. Patients with hematologic malignancies may be at an increased risk of severe COVID-19 due to immunosuppression related to the underlying disease and / or its treatment 1 . Sézary syndrome (SS) is a rare leukemic type of primary cutaneous lymphoma (PCL), defined by the triad of erythroderma, lymphadenopathy, and clonal T cells in the skin, lymph nodes, and peripheral blood 2 . Skin infections frequently occur at sites of breakdown caused by the disease, and may result in death 3 . In addition, chemotherapy and corticosteroids further increase the susceptibility to infection 4-5. The outcome of COVID-19 in these patients is unknown. Herein, we present two cases of patients with SS who developed COVID-19.

Case1 -A 56-year-old woman without co-morbidities was diagnosed with SS in June 2018. She presented with pruritic erythroderma (Figure 1 ) without palpable lymph nodes, and was treated with extracorporeal photopheresis and interferon alpha, with complete response. In March 2020 she presented with relapse of the skin lesions, and large bilateral inguinal lymph nodes. Biopsy of a lymph node was consistent with a diagnosis of large-cell transformation of SS. Chemotherapy with gemcitabine was started. On May 2020, she was admitted to the hospital with fever, chills and progressive cutaneous and nodal disease. She received broad-spectrum antibiotics and a nasopharyngeal swab was positive to SARS-CoV-2. Laboratory parameters are described in Table 1 . A chest-x ray was normal and computed tomography (CT) was not performed due to logistic reasons. The clinical course progressed, and palliative care measures were adopted. She died due to progressive SS five days after admission.

Case 2 -A 78-year old woman with well-controlled arterial hypertension and asthma was diagnosed with SS in February 2020. She presented with pruritic erythroderma and bilateral cervical and axillary lymphadenopathy. Treatment with dexamethasone and interferon alpha was started, with partial response. Six weeks later, the skin lesions worsened and gemcitabine was started. After two cycles of chemotherapy, the patient presented with fever and hypotension. She was admitted to the hospital and received broad-spectrum antibiotics. Hypotension was responsive to fluid resuscitation and the patient became afebrile. Cutaneous disease was stable. After 10 days, the patient developed dry cough and respiratory distress. Chest CT showed bilateral ground glass opacities affecting more than 50% of both lungs (Figure 2) . A nasopharyngeal swab was positive for SARS-Cov-2. Laboratory parameters are described in Table 1 . Oxygen supplementation was started, but respiratory failure progressed and she died 8 days after the onset of respiratory symptoms, under palliative care.

Patients with cancer who develop COVID-19 may have a poor outcome, especially if comorbidities are present 6 . SS is a rare disease that affects predominantly elderly patients. Treatment is usually started immediately in order to repair a severely damaged skin, and therefore reduce the risk of cutaneous and systemic infections. Corticosteroids and chemotherapy are frequently used and further increase immunosuppression. The course of COVID-19 in these patients is unknown and, to our knowledge, these are the first reported cases with the association of SS and COVID-19. While the optimal management of COVID-19 in such patients is unknown, experts recommend postponing chemotherapy in patients with stable disease 1 . The occurrence of COVID-19 in patients with progressive lymphoma is a great challenge. Our cases point to the dilemma: how to deal with patients who are at risk for severe COVID-19 and need immediate treatment for progressive neoplastic disease?
