RESUMO

OBJECTIVES: Monkeypox, a zoonotic orthopoxvirus, has spread to many countries in recent months, involving mostly men who have sex with men with multiple partners. Clinical presentation includes skin lesions, systemic signs, and less frequent skin superinfections or anorectal and ophthalmic involvements. We aim to detail cases of myocarditis attributable to monkeypox, an entity that has been poorly described. METHODS: This is a descriptive case series reporting three cases of myocarditis that occurred in patients infected with monkeypox in France in 2022. RESULTS: Patients were adult men with no medical history who had skin lesions with positive polymerase chain reaction for monkeypox virus. A few days after the onset of cutaneous signs, patients developed acute chest pain, elevated cardiac markers, and biological inflammatory syndrome compatible with myocarditis. Two patients presented electrocardiogram abnormalities and decreased ejection fraction associated with kinetic disturbances on transthoracic electrocardiography. The last patient had normal transthoracic electrocardiography and normal electrocardiogram, but cardiac magnetic resonance imaging showed segmental inferolateral acute myocarditis. Patients were hospitalized and received cardioprotective treatment. One received antiviral treatment with tecovirimat. Symptoms and laboratory abnormalities rapidly resolved in all patients. DISCUSSION: These cases suggest an association between monkeypox infections and cardiac inflammatory complications. The development of chest pain in an infected patient should not be underestimated and should lead to prompt investigations for myocarditis. Monkeypox infection should also be included in the differential diagnosis of myocarditis, particularly in at-risk patients such as men who have sex with men with multiple partners in whom complete examination for skin or mucosal lesions should thus be performed.

RESUMO

Cutaneous T-cell lymphomas (CTCLs) are non-Hodgkin lymphomas that develop primarily in the skin. They account for almost 80% of primary cutaneous lymphomas. Epidermotropic CTCLs (mycosis fungoides (MF) and Sézary syndrome (SS)) are the most common form of CTCL. The course of the disease ranges from an indolent clinical behavior in early-stage disease to an aggressive evolution in the advanced stages. Advanced-stage disease is defined by the presence of tumors, erythroderma, or significant blood, nodal or visceral involvement. Advanced-stage disease is characterized by frequent disease relapses, refractory disease, a severely impaired quality of life and reduced overall survival. In the last twenty-five years, allogeneic hematopoietic stem cell transplantation (HSCT) has led to prolonged remissions in advanced CTCL, presumably linked to a graft-versus-lymphoma effect and is thus emerging as a potential cure of the disease. However, the high post-transplant relapse rate and severe morbidity and mortality associated with graft-versus-host disease and infections are important issues. Allogeneic HSCT is thus mostly considered in young patients with no comorbidities and an aggressive, advanced-stage CTCL. Allogeneic HSCT gives the best results in patients with a pre-transplant complete remission of the lymphoma. For this reason, one of the challenges is to define the best time to consider allogeneic HSCT in the disease course. Early identification of patients at high risk for progression is important to identify candidates who may benefit from allogeneic HSCT before their disease becomes treatment-refractory. This review describes the role of allogeneic HSCT in CTCL, summarizes the published data and future perspectives in this area.

RESUMO

Primary cutaneous B-cell lymphomas are rare entities that develop primarily in the skin. They constitute a heterogeneous group that represents around a quarter of primary cutaneous lymphomas. The 2018 update of the World Health Organization-European Organization for Research and Treatment of Cancer (WHO-EORTC) classification differentiates primary cutaneous marginal zone lymphoma and primary cutaneous follicle center lymphoma with an indolent course from primary cutaneous diffuse large B-cell lymphoma, leg type with an aggressive behavior. The broad spectrum of clinical presentations and the disease course marked by frequent relapses are diagnostic and therapeutic challenges. The classification of these diseases has been refined in recent years, which allows to better define their immunopathogenesis and specific management. In the present article, we review the main clinico-biological characteristics and the current therapeutic options of these three main subsets. Based on the recent therapeutic advances in nodal B-cell lymphomas, we focus on the development of novel treatment options applicable to primary cutaneous B-cell lymphomas, including targeted therapies, combination treatments and immunotherapeutic approaches, and cover basic, translational and clinical aspects aiming to improve the treatment of cutaneous B-cell lymphomas.
