Summary
Testicular tumours represents 1% of neoplasms in adult men and 5% of all urological tumours in the world. Approximately 95% of all testicular tumours are germ cell tumours, while a smaller proportion of tumours develop from paratesticular structures including rete testis, epididymis and spermatic cord. Tumours of the rete testis are divided into cystic changes, non-neoplastic proliferations, benign and malignant tumours. Sertoliform cystadenoma of the rete testis is a rare benign tumour which occurs in all age groups and is clinically presented with painless palpable mass in the scrotum. Histologically, it mostly has a solid architecture and is composed of densely packed tubules lined with cubic to cylindrical epithelial cells of abundant pale cytoplasms, basally located nuclei and variably prominent nucleoli, similar to Sertoli cells. Immunohistochemically, tumour cells show a positive reaction to PAX8 and may be positive for sex cord-stromal markers such as inhibin, calretinin and SOX9. Radical or partial inguinal orchidectomy leads to complete cure, and no recurrences have been reported so no further oncological treatment is necessary. Here we present a case report of a patient with sertoliform cystadenoma of the rete testis who was treated with radical inguinal orchidectomy.
