Espectro clínico de la Enfermedad de Castleman

Castleman�s disease (CD) is a rare hematological disease characterized by hyperplasia of lymphoid nodules with two distinct histological and clinical patterns: hyaline - vascular which is usually single-center, low and aggressive behavior which gets exeresis healing in most of cases. The plasma cell variant is more aggressive clinical presentation mimics highgrade lymphomas and requires chemotherapy to eradicate. Play an etiopathogenic role HHV -8 and IL -6 and IL -1 cytokines. New drugs based on the blockade of IL -6 or its receptors have recently proved useful in the control of the disease. We present cases representing the spectrum of CD.La enfermedad de Castleman (EC) es una enfermedad hematológica rara caracterizada por hiperplasia de nódulos linfoides con dos patrones histológicos y clínicos bien diferenciados: hialino-vascular que suele ser unicéntrico, de comportamiento poco agresivo y cuya exeresis consigue la curación en la mayor parte de los casos.

Clinical characteristics and outcome of SARS-CoV-2 infection in admitted patients with chronic lymphocytic leukemia from a single European country

Spain has been one the most affected countries by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19) pandemic [1, 2]. Patients with chronic lymphocytic leukemia (CLL) could be at risk of more severe COVID-19 clinical forms [3] since they often carry immune perturbations aggravated by treatments used for the disease itself [4]. Two major series on patients with COVID-19 and CLL encompassing different countries and health systems reported heterogeneous factors related to the outcome [5, 6]. Herein, we are presenting the largest series of CLL patients with proved COVID-19 from a single country and Health system.Peer reviewe
