title: Pelvic "lipolymph nodes": a consideration in the differential diagnosis of pelvic masses.
abstract: Twelve patients with pelvic "lipolymph nodes" were seen at the Mayo Clinic during a period of 26 years. Most of the patients were perimenopausal or postmenopausal, and all but one were obese. The average size of the nodes was 6.6 cm, with the range being 2 to 14 cm. The most frequently involved nodes were the external iliac and obturator groups. Excretory urography and pelvic ultrasound scan (high-resolution scanner) were helpful in determining the extraperitoneal location and the solid nature of the tumors. Lymphangiography performed in one case was helpful in confirming the nodal origin of the pelvic tumor. Exploratory laparotomy was required to determine the exact nature of the lesion in all patients. The treatment consisted of simple removal of the involved nodes. No recurrences have been observed.
