RT Journal Article SR Electronic T1 Simultaneous excision of pelvic lipoma and robot-assisted radical prostatectomy JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e254813 DO 10.1136/bcr-2023-254813 VO 16 IS 3 A1 Dranova, Sabina A1 Carbin, Danny Darlington A1 Perry, Matthew A1 Abou Chedid, Wissam YR 2023 UL http://casereports.bmj.com/content/16/3/e254813.abstract AB Lipoma is a benign mesenchymal tumour that can develop in any part of the body containing adipose tissue. Very few cases of pelvic lipomas have been reported in the literature. Due to their location and slow growth, pelvic lipomas are often asymptomatic for a prolonged time. Thus, on diagnosis, they are usually found to be of considerable size. Due to their size, pelvic lipomas can present causing bladder outlet obstruction, lymphoedema, abdominal and pelvic pain, and constipation, as well as present with deep vein thrombosis (DVT) like symptoms. Patients with cancer have a much higher risk of developing DVT. Here, we describe a case of an incidental finding of pelvic lipoma mimicking DVT in a patient with organ-confined prostate cancer. He eventually underwent simultaneous robot-assisted radical prostatectomy and lipoma excision.
