Jae Hyun Ryu, Jung Woo Oh, Kwang Ho Kim, Joon Il Choi, Kyoung Ho Ryu, Yoon Jung Kim, Tae Young Jung From the Departments of Urology and Pathology, Seoul Veterans Hospital, Seoul, Korea Castleman disease, or angiofollicular lymph node hyperplasia, is a fairly rare benign tumor of lymphoid origin. Most cases tend to present as a mediastinal mass. We report a 58-year-old man with Castleman disease...

A 70-year-old female complained of palpitation. CBC demonstated anemia and bone marrow aspiration smear demonstrated absence of erythroid hematopoietic cells, and pure red cell aplasia (PRCA) was diagnosed. Computed tomography (CT) demonstrated abdominal tumor. Biopsy of the abdominal tumor showed proliferation of lymph follicles with small and medium-sized lymphocytes, angiofollicular pattern ...

INTRODUCTION Castleman's disease or angiofollicular lymph hyperplasia is a rare disease with two identified clinical forms. Unicentric or localized form is characterized by isolated growth of lymph nodes, most often in mediastinum, and multicentric form is expressed as systemic disease with spread lymphadenopathy, organomegaly and presence of general symptoms of the disease. Histological types ...

Castleman and Towne described a disease presenting as a mediastinal mass resembling thymoma. It is also known as "giant lymph node hyperplasia", "lymph node hamartoma", "angiofollicular mediastinal lymph node hyperplasia", and "angiomatous lymphoid hyperplasia". The pathogenesis is unknown, but the bulk of evidence points toward faulty immune regulation, resulting in excessive B-lymphocyte and ...

Introduction. Angiofollicular lymph node hyperplasia (Castleman's disease) is a nonmalignant lymphoproliferative disorder that generally involves the lymph nodes of young adults, most commonly in the mediastinum. Rarely, Castleman's disease may present in the parotid gland. The disease can be further classified into unicentric or multicentric forms, with considerable differences in presentation...

Background. Castleman's disease (CD), also known as angiofollicular node hyperplasia, is a rare heterogenous lymphoproliferative disorder. This disease exists as two distinct entities: a localized or unicentric CD (UCD) which has a more benign clinical course and multicentric CD (MCD) which is a systemic disease and carries a worse prognosis. MCD is often associated with human immunodeficiency ...

BACKGROUND Castleman's disease, or angiofollicular lymphoid hyperplasia, is a rare disorder and can be easily misdiagnosed as lymphoma, neoplasm, or infection. The diagnosis is challenging due to the nonspecific signs and symptoms as well as the rarity of the disease. We present an unusual case of a young girl presenting with an enlarging pulmonary mass that was believed to be infectious in ori...

BACKGROUND Multicentric Castleman's disease (MCD) in human immunodeficiency virus (HIV)-infected patients is an aggressive form of lymphoproliferative disorder that usually has a rapidly fatal outcome. Overall mortality is 70%-85%, and median survival is only 8-14 months. No standard or optimal therapy for MCD has been established. CASE A 49-year-old man with HIV infection presented with 1-we...

Castleman disease, or angiofollicular lymph node hyperplasia, is a rare lymphoproliferative disorder of unknown etiology and pathogenesis. Its importance lies in the fact that it has been associated with human immunodeficiency virus (HIV) and human herpes virus 8, as well as other neoplastic diseases such as Kaposi’s sarcoma, lymphomas, and POEMS syndrome (polyneuropathy, organomegaly, endocrin...

BACKGROUND Castleman's disease or angiofollicular lymphoid hyperplasia is a rare benign lymph node hyperplasia usually presenting as an asymptomatic mediastinal mass in children. The disease can present at any extra thoracic site with lymphoid tissue such as retroperitoneal, mesentery, axilla, and pelvis. Hepatic localization castleman disease is very rare in children. Herein, we reported a cas...
