Appendiceal mucocele - Case Report and Review of the Literature.

Appendiceal mucocele (AM) was described for the first time by Rokitansky in 1842.1 Its incidence is 0.2 - 0.4% of all apendectomies performed, as it is observed predominantly in women with the ratio of 4/1 versus men and most frequently at the age of 50.2,3 We present to your attention a 64-year-old woman, who was referred to diagnostic further clarification after a preventive gynaecologic exam. Appendiceal mucocele with retrocecal location, enveloped by additional Jackson'™s membranes was determined intraoperatively. The formation has been dissected and appendectomy was performed without mucocele integrity being compromised. The permanent histological specimen revealed mucinous cystadenoma with clear resection lines, without any data on the appendiceal base being affected. The patient was discharged on the third day after surgery without any complications, and further follow-up was scheduled in 6 months.

Extraskeletal Osteosarcoma of the Omentum with Aggressive Development.

For the first time extraskeletal osteosarcomas (ESOS) were described by Wilson in 1941. They are extremely rare neoplasms, presenting 4% of all osteosarcomas and 1,2% of all soft-tissue sarcomas. About 300 cases have been reported in the literature up to date. We present a 66-year-old female patient, admitted in the clinic because of acute bleeding in retroperitoneal space. Revision of the retroperitoneal space and haemostasis were performed. The patient was re-operated because postoperative bowel obstruction. The reason for it was intestinal infiltration from large tumor of the omentum, determined histopathologically as ESOS. The case was considered as an unresectable neoplasm so a colostomy was performed. In the literature we found 3 case reports of ESOS, originated from omentum.
