Adenofibromas of the testicular parenchyma are exceptional with only one case published in the literature. Whereas adenofibromas of mullerian derivatives are well described, testicular tumours resembling surface ovarian epithelium are rare. We describe a case of adenofibroma discovered incidentally while investigating for a hydrocoele in a 57-year-old patient. Histological and immunohistochemical evaluation confirmed the lesion as being a serous adenofibroma with immunohistochemical properties analogous to its ovarian counterpart. These lesions are to be considered in the differential diagnosis of unusual cystic lesions of the testis, in order not to confuse it with more sinister pathology.
