Idiopathic peritesticular fibrosis associated with retroperitoneal fibrosis.
A 32-year-old male who presented with idiopathic retroperitoneal fibrosis developed peritesticular fibrosis 4 years later. The lesion appeared as a diffuse, uniform thickening without a tendency to form nodules. Histologic examination revealed a densely collagenized tissue with scattered cells, consisting mainly of fibroblasts and plasma cells. Small blood and lymphatic vessels of the tumor showed luminal dilation and perivascular edema with inflammatory infiltrates. No other associated pathology was found in the patient. We suggest that peritesticular fibrosis in this patient may be due to lymphatic drainage obstruction caused by retroperitoneal fibrosis.
