Retroperitoneal fibrosis (RF) is a benign neoplasm consisting of a proliferation of fibroblasts and collagen fibrils.1 Its cause is unknown in two thirds of the cases, while in the remaining cases it is associated with drugs, retroperitoneal hemorrhage, surgery, and other causes.2 Until now, to our knowledge, it has never been observed in patients with human immunodeficiency virus (HIV) infection. We describe a patient with HIV infection who underwent successful treatment of RF with tamoxifen citrate without recurrence in the 5 years following treatment.
