Laparoscopic resection of a large mixed epithelial-stromal tumour of the seminal vesicle: a rare entity and review of the current literature

Mixed epithelial-stromal tumours (MESTs) of the seminal vesicle (SV) are a rare neoplasm, with biological behaviour ranging from benign to malignant. Due to their rarity, there are no established guidelines for their treatment. We report a 37-year-old man with a large MEST of the SV which was succes...

Description
Summary:Mixed epithelial-stromal tumours (MESTs) of the seminal vesicle (SV) are a rare neoplasm, with biological behaviour ranging from benign to malignant. Due to their rarity, there are no established guidelines for their treatment. We report a 37-year-old man with a large MEST of the SV which was successfully resected by laparoscopic transperitoneal approach. Amidst the controversy regarding the nomenclature and grading of MESTs in literature, we reclassified the previous reports of MESTs incorporating both the WHO and Reikie et al grading.
