Mesenteric angiofollicular lymph node hyperplasia (lymphoid hamartoma) with nephroitc syndrome.

In an 18-year-old woman who presented with the nephrotic syndrome and an abdominal mass, removal of a benign mesenteric lymphoid tumor was associated with remission of the nephrotic syndrome without further recurrence (30 month follow-up). Biopsies of both kidneys showed a minimal-change glomerular lesion. Clinical and pathologic characteristics of angiofollicular lymph node hyperplasia and its possible relationship to the nephrotic syndrome are discussed.
