BESTARD VALLEJO, J.E. et al. Adenomatoid tumour of epididymis: the most common tumour of the paratesticular structures. Actas Urol Esp [online]. 2008, vol.32, n.6, pp.611-617. ISSN 0210-4806.

Introduction: Paratesticular tumours are rare but generally benign neoplasms, usually treated by local excission. Adenomatoid tumours of epididymis are the most common of these tumours. Objectives: Analyze paratesticular tumours treated in our center and describe dyagnosis and treatment of adenomatoid tumours of epididymis. Material and Methods: We retrospectively review 8 patients with paratesticular tumours treated from July 1997 to July 2007. We analyze clinical presentation, dyagnostic suspicion given by image technique, treatment followed and final dyagnosis. Results: Patients median age was 44.1 years (22-69), presenting most of them subacute scrotal tumour with median size by ultrasound of 2.8 cm (1.5-7). All of them were locally extirpated except one with suspicion of a malignant polyorchidism and another one with an apparently intratesticular lesion of great size. Just in two cases peroperatory biopsy was performed. Dyagnosis was in 4 cases adenomatoid tumour of epididymis, in two cases fibrous pseudotumour of epididymis, in one case leiomyoma of epididymis and in one case angiolipoma of spermatic cord. Just in one case diagnosed of adenomatoid tumour of epididymis ultrasound confirmed solid tumour suggesting the final dyagnosis. Conclusions: Adenomatoid tumors of epididymis are rare tumours which may present at any age. Ultrasound may help in dyagnosis, but its capacity to distinguish this lesions is low. Benignity of adenomatoid tumour of epididymis as well as most of the other paratesticular tumours should make local excission the treatment of choice and, when any doubt existed, peroperatory biopsy should be performed.
