Fibroepithelial polyp in a child.

Only 15 cases of fibroepithelial polyp in children have been reported in the world medical literature. Clinical differentiation between this tumor and a malignant ureteral tumor is difficult and often results in unnecessary nephrectomy. We report the sixteenth case of a child with fibroepithelial polyp of the ureter.

Corticosteroid treatment for pulmonary lymphoid hyperplasia in children with the acquired immune deficiency syndrome.

Five children with positive serology for human immunodeficiency virus (HIV) infection by enzyme-linked immunosorbent assay and Western blot were followed for chronic pulmonary disease. Lung biopsies were performed in all patients, and confirmed the diagnosis of pulmonary lymphoid hyperplasia. All children demonstrated progressive hypoxia and increasing alveolar capillary oxygen gradients over at least 1 year of follow-up.
