There are two distinct subtypes of Castleman disease: unicentric Castleman disease Ferry, in Diagnostic Pathology of Infectious Disease (Second Edition), 2018. (c) The majority of mature plasma cells are positive for IgG4 (IgG4 + /IgG + plasma cell ratio >70%). The atypical lymphoid follicles could be regarded as a bone marrow manifestation of multicentric Castleman disease, whereas the plasmacytosis most likely is the result of excess interleukin 6 production. Lesions vary in shape and size and can grow up to 1.5cm in diameter. It is usually associated with HIV infection. Castleman's disease (CD), 6, 7 first described as localized mediastinal lymphadenopathy or giant lymph node hyperplasia, is an uncommon, episodic, polyclonal lymphoplasmacytic disorder.

Clin. Nearly all cases of hyaline-vascular Castleman disease, and a minority of plasma cell Castleman disease, are localized—that is, the disorder affects a single anatomic site or a single group of lymph nodes. Nearly all cases of hyaline-vascular Castleman disease, and a minority of plasma cell Castleman disease, are localized—that is, the disorder affects a single anatomic site or a single group of lymph nodes. The pathologic hallmark of PLCH is the accumulation of Langerhans and other inflammatory cells in small airways, resulting in the formation of nodular inflammatory lesions. Lymphadenopathy is frequently observed in patients with immunoglobulin G4-related disease (IgG4-RD) and sometimes appears as the first manifestation of the disease. Unicentric Castleman disease typically occurs in children and young adults (3 rd and 4 th decades), with a slight female predominance (1.4:1) 15..
