Abstract
BACKGROUND

Scrotal lipoma is exceedingly rare, so its origin is still unknown. Injury is suggested as a potential factor, but the cause remains unclear. It is difficult to determine the origin of these tumours. Previous studies have suggested that these tumours may be congenital or that they originate from small fatty particles around the cord. Other studies have suggested that these tumours originate from testicles or the tunica.

CASE SUMMARY

A 66-years elderly male with giant scrotal mass. B-ultrasound, computed tomography and magnetic resonance imaging examinations are typical lipoma-like changes, which were confirmed by postoperative pathological analysis. Abnormal somatic fat distribution was confirmed by images. no recurrence after follow-up for 2 years. Previously published English-language literature was reviewed, and a history of inguinal or pelvic surgery was reported in 6 studies (total 21 cases). To our knowledge, this is the heaviest bilateral scrotal lipoma in the English-language literature, and it has the longest postoperative follow-up time. More importantly, the origin of these tumours is reviewed and discussed.

CONCLUSION

Giant bilateral scrotal lipoma in elderly may as part of the symptoms of abnormal somatic fat distribution.

Core Tip: A case of giant bilateral scrotal lipoma was reported, and the literature was reviewed. A 66-year-old male with a giant scrotal mass was evaluated. Surgical treatment was performed, and scrotal lipoma were confirmed by postoperative pathological analysis. This is the heaviest bilateral scrotal lipoma in the English-language literature, and it has the longest postoperative follow-up time. More importantly, the origin of these tumours is reviewed and discussed.
