Wolffian duct cyst

Laparoscopic Removal of Voluminous Right Seminal Vesicle Neoplasm

Introduction

We present the case of a male adnexal tumor of probable Wolffian origin occurred to the right seminal vesicle of a 47–year-old man.

Materials and Methods

The patient presented with a 2–month history of hematospermia. The diagnosis was achieved by transrectal ultrasound, CT of the abdomen and pelvis, and biopsy of both prostate and seminal vesicle. The patient was counseled for laparoscopic excision of the right seminal vesicle.

Results

The right seminal vesicle, along with the tumor and the right vas deferens, were excised and clear margins were ensured by frozen section. Total operative time was 180 with 200 mL blood loss. The patient's recovery was uncomplicated and he was discharged on the fourth post-operative day. The histologic examination demonstrated a male adnexal tumor of probable Wolffian origin, which is a rare low-grade malignant neoplasm that has been previously described in the broad ligament, ovaries and retroperitoneum of females. The patient is free of relapse at a 20–month follow-up.

Conclusions

This is the second report of this entity in a male. The laparoscopic approach for the excision of seminal vesicle neoplasms is a good treatment for its obvious benefits of minimal blood loss, short hospital stay and quick return to normal activity. The magnifications of the anatomical details of the pelvic floor help the surgeon in the dissection of the seminal vesicle from the other structures.

Male adnexal tumour of probable Wolffian duct origin

Male adnexal tumours of Wolffian duct origin are very rare. They have variable malignant potential and surgical excision is recommended. We report the case of a 56-year-old male who presented with a swelling in the perineum thought to be a haematoma as the result of a complication of a laparoscopic inguinal hernia repair. It recurred after incision and two attempts at drainage and was then completely excised. Histology revealed the lesion to be an adnexal tumour of probable Wolffian duct origin. To our knowledge there have only been two previous cases of male adnexal tumour of Wolffian duct origin reported in the literature.
