Giant lipomas are uncommon. We herein report a case involving a giant, deep\u2010seated dumbbell\u2010shaped intermuscular lipoma in the right thigh that extended into the pelvic region through the obturator foramen and caused obturator neuropathy. A 64\u2010year\u2010old man with numbness while walking was diagnosed with a 17\u2009\u00d7\u200916\u2010cm lipomatous tumor. He underwent radical surgery performed by a multidisciplinary team consisting of orthopedic and colorectal surgeons. High\u2010definition magnified laparoscopic images of the deep pelvis confirmed that tumor had infiltrated the obturator nerve. The tumor was completely resected with the obturator nerve. Six months after surgical resection, the patient had no gait disturbance or evidence of recurrence. The laparoscopic approach for this kind of complicated deep pelvic surgery was safe and feasible when performed by colorectal surgeon with ample knowledge of the pelvic anatomy.<\/jats:p>","DOI":"10.1111\/ases.12700","type":"journal-article","created":{"date-parts":[[2019,3,20]],"date-time":"2019-03-20T05:48:58Z","timestamp":1553060938000},"page":"114-116","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Laparoscopic
