Hyaline vascular type Castleman disease (HV-CD) is a rare but distinct benign lymphoproliferative disorder that is a subtype of unicentric Castleman disease (UCD). Its lack of symptoms, unusual histopathological patterns, and localized appearance frequently make it hard to tell apart from lymphomas or other reactive lymphadenopathies. To avoid overtreatment, it is important to recognize and correctly differentiate quickly, since complete surgical excision is typically curative. Castleman disease (CD) is a rare, non-clonal lymphoproliferative disorder that shows up as a group of different types of lymph node growths. The hyaline vascular type (HV-CD) is the most common histological variant found in unicentric CD (UCD). It usually has a benign, asymptomatic course.
