“…If cystadenoma was an MEST, it would be necessary, by definition, the coexistence of a proliferation of both the glandular and stromal compartments. However, stroma overgrowth may be not necessary for the diagnosis of cystadenoma, 1,6–8,13,17,22 In some papers, 1,13,15,16,27 the description of the stroma is absent. To overcome this evidence, Reikie et al 6 suggested that the term ‘cystadenoma’ should therefore be restricted only to those rare benign tumours that demonstrate hypocellular (normal or almost normal) seminal vesicle stroma and they can be considered part of the spectrum of the low-grade MEST, rather than a separate category.…”

“…After surgical removal, on gross examination, these neoplasms appear variably cystic and solid or multicystic and sponge-like. Microscopically, these tumours show variable dilated cysts, lined by a cuboidal to columnar cells, 1–9 from single-layered 10 to double-layered 8 or flattened 1 epithelium containing (not in all of the cysts) a homogeneous eosinophilic material. Some authors described a basal cell layer, 9,11 some only recognised it focally, 6 others did not find it at all.…”

Background: Cystadenomas of the seminal vesicles are benign cystic tumours, currently classified into the group of mixed epithelial-stromal tumours (MEST). Primary tumours arising in the seminal vesicles are quite rare, benign tumours being rarer than malignant ones, with only a few cases reported in the English literature since 1944. Cystadenomas represent a potential diagnostic pitfall, as they can be clinically confused with malignant neoplasms and histologically with non-neoplastic inflammatory lesions or other cystic tumours, even malignant. Objective and methods: We report a case of a 23-year-old man presenting with a cystic mass of the seminal vesicle, clinically suspected to be a malignant neoplasm. On pathological examination, a diagnosis of cystadenoma was made. Diagnostic criteria to make a diagnosis of this tumour are questionable. Therefore, we carried out a literature review in attempt to compare clinico-pathological findings of 28 cases reported in the English literature as cystadenomas of the seminal vesicle. Results: Only 28 cases of cystadenomas of seminal vesicles were reported in the English literature. The available data show the difficulty to rule out malignancy preoperatively in a patient with a solid-cystic mass in the pelvic region, and that morphological findings observed were often reported incompletely. Conclusions: The current classification appears debatable, as well as histopathological criteria to diagnose a cystadenoma of the seminal vesicle. For the proper management of these lesions, a multidisciplinary approach is mandatory. Level of evidence: Not applicable

“…The histological findings demonstrated that the tumors were composed of glands and cysts that were lined predominantly by cuboidal and columnar epithelium surrounded by fibrous stroma. [ 16 ] Reikie et al [ 17 ] proposed that the term seminal vesicle “mixed epithelial-stromal tumor” should be used to designate tumors of the seminal vesicle containing epithelial and stromal components. According to their criterion, cystadenoma of the seminal vesicle can be considered a low-grade mixed epithelial-stromal tumor.…”

Rationale: Schwannomas of the seminal vesicles are extremely rare, and only cases of single seminal vesicle schwannomas have been reported. Here, we report a case of multiple schwannoma of the seminal vesicle. Patient concerns: We report a rare case of multiple schwannoma of the seminal vesicle that occurred in a 48-year-old man during physical examination. Multiple mixed masses in the left region of the seminal vesicle were documented with transrectal ultrasonography and magnetic resonance imaging. The patient presented no clinical symptoms, no family history of the disease and no history of genetic disease. Diagnosis: Postoperative pathology revealed a diagnosis of seminal vesical schwannoma. Interventions: The patient underwent robotic-assisted laparoscopic surgery to remove the mass. Outcomes: The patient recovered rapidly and the length of hospitalization was 6 days after operation. At present, there is no recurrence in 10 month follow up. Lessons: Whether benign or malignant, single or multiple, schwannomas still need to be diagnosed by pathology because of the limitations of examination methods. Surgical resection is still the preferred treatment.

Laparoscopic vesiculectomy for large seminal vesicle cystadenoma

et al. 2018

Cystadenomas of the seminal vesicles are extremely rare. Here, we report a large seminal vesicle cystadenoma. A 37‐year‐old man presented a 6‐month history of haemospermia, 10 days of Lower Urinary Tract symptoms (LUTSs) and gross haematuria. Transabdominal ultrasonography, computed tomography and magnetic resonance imaging were performed and revealed a large solid‐cystic pelvic mass morphometrically measured 7.0 cm × 11.9 cm × 8.6 cm on the right seminal vesicle, which caused hydronephrosis of the right kidney. The prostate‐specific antigen of the patient was 27.860 ng/dl. Laparoscopic exploration found the capsule of tumour was complete and the tumour came from the right seminal vesicle, in addition, the mass had a certain space with the bladder and prostate, which could be separated. So a nerve‐sparing Laparoscopic Vesiculectomy was performed at last, even though the intraoperative frozen section analysis could not make sure the nature of the tumour either. The postoperative pathology revealed cystadenoma of the seminal vesicle.
