Retroperitoneal Sarcoma constitue 1-2% of all solid tumors and 10-20% of all sarcomas are retroperitoneal.

The most common type of sarcomas are different in different series. Bailey says liposarcoma is most common where as some series say MFH (Malignant fibrous histiocytoma). These lesions tend to have a pseudocapsule and that should be completely removed. These tumors can achieve a large size in retroperitoneum before producing symptoms.

Pain and fullness in abdomen are common symptoms

Surgery is the mainstay of treatment.Cell type has no implications on prognosis and survival

They frequently have pulmonary metastasis

Ref Bailey 986

7. c

From the question it is clear that this is a case of intestinal obstruction.Tender swelling at the previous site gives hint that this is an obstructed hernia at the site of previous ileostomy.

It could have been adhesive but the tell tale sign is at the site of previous colostomy

It is not an anastomotic leak because that would manifest early and not after 10th day

Ileus does not have pain 

8. c

This patient has steatorrhoea (pale sticky bulky stools) which is due to the deficiency of lipase. Lipase is responsible for breakdown of fats into fatty acids and triglycerides and its deficiency leads to foul smelling bulky stools.

9. c

Boerhavve's syndrome is a full thickness perforation of esophagus at the left lower end usually after a heavy meal. It is a spontaneous perforation and often misdiagnosed as a cardiac event.

Binge alcohol drinking with vomiting and retching leads to increased intraluminal pressure 

Mortality is 20-30% if not treated at time. 

Perforation is most commonly at the left lower end and not confined to the defect which is seen. It can extend either way under the muscularis and requires myotomy to see the full longitudinal extent. Layered cloure with intercostal muscle flap should be done

10. d

Ureters join the posterior surface of urinary bladder. The apex of the bladder is connected to the umbilicus by the median umbilical ligament, which is a remnant of the urachus.
