[X-ray morphology and clinical signs of angiofollicular lymph node hyperplasia].

Five patients with benign angiofollicular lymphoma are reported - four with involvement of the mediastinum and one with abdominal disease. Chest X-rays and an intravenous pyelogram show the characteristic features of the disease. There are two histologic variants of this rare disease--one with and one without clinical symptoms. The reported cases to some extent follow this pattern described in the literature.
