Multicentric Castleman disease (MCD) is a rare nonmalignant lymphoproliferative disorder presenting systemic symptoms such as fever, night sweats, fatigue, anemia, effusions, and multifocal lymphadenopathy. The etiology of MCD has not been clarified to date. The coexistence of MCD with chronic myelomonocytic leukemia (CMML) has been rarely reported. Although the pathogenesis remains unclear, th...

We read with great interest the article by Deisseroth and colleagues (1) focusing on the recent global approval of the monoclonal IL6 antibody siltuximab for the treatment of patients with HHV-8-, HIV-negative multicentric Castleman disease (MCD). Up to now, treatment options for this rare lymphoproliferative disorder are very limited. Lately, the phase III, double-blind, randomized trial of va...

In collaboration with an international cohort of clinicians and pathologists who reviewed more than 240 cases, the authors concurred on a set of evidence-based criteria, thereby paving the way for a uniform approach to managing this enigmatic condition. In 1956, Castleman et al described clinicopathologic features of 13 asymptomatic patients who presented with a mediastinal mass. This form of u...

Currently, of less than 50 cases of head and neck follicular dendritic cell (FDC) sarcoma reported in the literature, 5 have been found to occur in the background of Castleman disease. We report another case of head and neck FDC sarcoma with emphasise on its associated lesions and review the outcome of treatment from the existing cases in the literature.

Background Multicentric Castleman Disease (MCD) is an idiopathic lymphoproliferative disorder, exceptionally reported in children, probably due to an increase of interleukin 6 secretion. MCD is characterized by systemic lymphadenopathy and constitutional inflammatory symptoms including severe growth retardation. Previous studies in adult showed that anti-interleukin 6 receptor antibody alleviat...

castleman's disease is an uncommon cause of lymph node enlargement that mostly involves the mediastinum and lung hilum. it is divided into 2 types: localized, which is usually asymptomatic and presents with a mass lesion; and multicentric, which is characterized by chills, anemia, generalized lymphadenopathy and hepatosplenomegaly. an extrathoracic site of involvement is very uncommon, and may ...
