Castleman disease (CD), also known as angiofollicular lymph node hyperplasia and giant lymph node hyperplasia, was first described in 1956 by Dr. Benjamin Castleman as localized mediastinal lymph node proliferation. Nodal hyperplasia has been described as hyaline vascular (80–90%), plasma cell (10–20%), and mixed.1 CD is a rare disease with no racial or sex predominance.2 Clinical characteristi...

We report this case of secondary amyloidosis associated with Castleman's disease. A 51-year-old man presented with systemic symptoms of generalized weakness, fatigue, unintended weight loss, anorexia and progressively worsening abdominal distension. On examination he was found to have an indurated right-sided submandibular mass and tense ascites. He was found to have multiorgan dysfunction with...

We report a case of unicentric Castleman's disease (angiofollicular lymph node hyperplasia) with abdominal localization, that was treated laparoscopically. The patient, a 23-year-old male, was referred to our unit for subtle symptoms of recurrent palpitations and vague abdominal pain. His physician had prescribed an abdominal echtomograph, which showed a mass located at the lower and anterior l...

The developmental program that regulates thyroid progenitor cell proliferation is largely unknown. Here, we show that branching-like morphogenesis is a driving force to attain final size of the embryonic thyroid gland in mice. Sox9, a key factor in branching organ development, distinguishes Nkx2-1+ cells in the thyroid bud from the progenitors that originally form the thyroid placode in anterio...

Castleman's disease is a distinct form of lymph node hyperplasia divided into a solitary and a multicentric type. The solitary type occurs most commonly in the mediastinum and is usually asymptomatic. We present a patient with Castleman's disease of the hyaline-vascular solitary type located in the retroperitoneum. The patient was a 38-year-old male, who presented to our hospital with fever. Th...

Introduction . Castleman disease (CD) is a rare lymphoproliferative disorder also known as angiofollicular lymph node hyperplasia or giant lymphoid hyperplasia. CD considered unicentric in the presence of single focus and if clinical picture represented by multiple lymphadenopathy systemic manifestations, it multicentric. Manifestation occurrence that mimics tumor meninges brain extremely rare,...

Castleman’s disease (CD) is a rare lymphoproliferative disorder of unknown cause. In even rarer circumstances, it can be associated with POEMS (peripheral neuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and sk in changes) syndrome. We report a case of multicentric plasma cell CD with POEMS syndrome, who presented with inguinal masses and lower extremity weakness for years. Compu...

INTRODUCTION Castleman's disease, also known as angiofollicular lymph node hyperplasia, is a rare disease with two known expansion types, unicentric and multicentric, which play a major role in determining therapy. We focus here on the unicentric type, which can be treated and cured by surgery. To date, approximately 1000 cases of Castleman's disease have been reported in the literature. CASE...

A simian homologue of Kaposi's sarcoma-associated herpesvirus (KSHV), the eighth human herpesvirus (HHV8), was isolated from a simian immunodeficiency virus (SIV)-infected rhesus macaque (Macaca mulatta) that developed a multicentric lymphoproliferative disorder (LPD). This simian rhadinovirus is genetically similar to a recently described rhesus rhadinovirus (RRV) (Desrosiers, R.C., V.G. Sasse...
