The stroma-rich variant of Castleman¡¯s disease of the hyaline-vascular type (CDHV) is a rare entity that shows overgrowth of a variety of stromal cells in the widened interfollicular (IF) area. We report here on a case of a stroma-rich variant of CDHV in an 18-year-old man who presented with an asymptomatic solitary neck mass he¡¯d had for 1 year. Histologically, an enlarged lymph node fulfilled the criteria of CDHV, along with vague nodularity of a widened IF area. The nodular lesion consisted of numerous vessels and a proliferation of spindle cells. Immunohistochemically, the spindle cells were positive for vimentin and smooth muscle actin, they were negative for desmin, CD21, CD34, CD68, ALK-1, and S-100 protein. This stromal lesion is typically hyperplastic and clinically benign, and it must be distinguished from neoplastic stromal proliferation associated with Castleman¡¯s disease because of its potential for recurrence and metastasis.
