Angiofollicular lymph node hyperplasia: a comparison of unicentric, multicentric, hyaline vascular, and plasma cell types of disease by morphometric and clinical analysis.

A morphometric and clinical analysis of 47 cases of angiofollicular lymph node hyperplasia (AFLH) demonstrated morphometric differences between plasma cell (28 cases) and hyaline vascular (19 cases) AFLH. Twenty-one AFLH cases were unicentric, and 26 cases were multicentric. Plasma cell types of AFLH, defined by standard morphologic and objective morphometric assessment, were associated with systemic clinical and laboratory abnormalities. Unicentric or hyaline vascular AFLH was amenable to surgical therapy, and multicentric or plasma cell AFLH without neuropathy was amenable to steroid treatment or chemotherapy with good prognoses. Multicentric or plasma cell AFLH with neuropathy was associated with resistance to steroids and chemotherapy and with a poor prognosis.
