An exrathoracic presentation of castleman's disease.

Castleman's disease, also known as angiofollicular hyperplasia, usually occurs in the mediastinum and rarely in cervical region as solitary mass. Histopathologically four variants have been recognized (Castleman et al. Cancer 1954;9:822-30) hyaline vascular type-most common type (Keller et al. Cancer 1972;29:670-83) plasma cell type (Salisbury, Pediatric Pathol 1990;10:609-15) transitional type (Shahidi, Mayo Clinic Proc 1995;70:969-77) stromal rich type. We report a case of Castleman's disease of typical histopathological picture of angio follicular hyperplasia arising from the right carotid triangle of neck in 12-year-old child without any associated systemic illness.
