Abstract
Castleman’s disease is a rare pathological entity, which comprises a heterogeneous group of histopathological disorders of the lymph nodes. It can be classified as unicentric Castleman’s disease, when it involves the growth of a single lymph node or lymph nodes of the same region, or in multicentric Castleman’s disease if it affects adenopathies of different ganglionic regions. Both types of Castleman’s disease differ in incidence, epidemiology, and clinical course. The unicentric Castleman disease has an estimated incidence in the United States between 15.9 to 19.9 cases per million person-years, occurs mainly in young people, around the third decade of life and is more frequent in women. The causal factors of this pathology are unknown. The clinical manifestations depend on the histological variant, with the hyaline vascular variant being more frequent, which is usually asymptomatic. The confirmatory diagnosis of the unicentric Castleman disease is histological. Complete nodular resection is the treatment of choice, while radiotherapy and chemotherapy are therapeutic options for non-resectable lesions. The prognosis of the disease is benign, with an associated mortality to 10 years of 4% and percentages of cure around 95%.
