Retroperitoneal lymphadenopathy

Stage III consists ofextrapelvic peritoneal implants and/or inguinal or retroperitoneal lymphadenopathy. Peritoneal lesions outside the pelvis, omental, or mesenteric implants are typical findings in stage III ovar-... 

Ulcerations, necrosis, and fistulae between adjacent bowel loops may appear. Regional, mesenteric, and retroperitoneal lymphadenopathy may be present. Another focal form of lymphoma is the endo-eccentric mass with large ulcerations involving adjacent bowel loops where fistulae can appear (O Connell and Thompson 1978). 

The commonest malignant cause of mid-ureteric obstruction is extrinsic compression by metastatic lymphadenopathy retroperitoneal tumors are less common and are listed in Table 7.1.
