First report of testis‐sparing surgery for sertoliform cystadenoma: case presentation and review of literature

Introduction Sertoliform cystadenoma is a very rare, benign lesion of the rete-testis difficult to distinguish from other malignancies of the testicle. Case presentation We present the case of a 42-year-old male who presented with a right testicular mass, asymptomatic for 1 year. Clinical examination revealed a palpable, painless, and well-delimited right testicular superior pole nodule. Testicular ultrasound confirmed the nodule, whereas serum tumoral markers were normal. The patient underwent inguinal partial orchiectomy. Intraoperative excisional biopsy and frozen section pathology were performed, reporting undetermined tumoral origin with negative surgical margins. Ischemia time was 12 minutes. The final pathology report showed a Sertoliform cystadenoma of rete testis, with immunomorphology positive for AE1, CK7, and negative surgical margins. Conclusion To our knowledge, this is the first report of testicular sparing surgery for Sertoliform cystadenoma, a very rare benign tumor of rete testis. All previously reported cases were managed by radical inguinal orchidectomy.
