Microscopically papillary formations and cystadenomas are mesonephric in origin, arise from the efferent ductules and are the only epididymal tumours of purely epithelial origin. Some consider them to be hamartomas. In the presence of bilateral lesions or predominantly solid lesions larger than 14 mm, the diagnosis of VHL disease should be strongly considered. Pathologically, papillary cystadenoma must be differentiated from metastatic renal cell carcinoma, which is also common in patients with VHL disease [7]. The differential diagnosis includes adenomatoid tumours, epididymal cysts and, when the mass is predominantly cystic, spermatocele.

Other benign epididymal tumours include cavernous haemangioma and teratoma.
