Pseudomyxoma peritonei (PMP) is a rare tumor that usually originates in the appendix, but a small number of cases originate in the ovary. Lynch syndrome (LS) is an autosomal dominant hereditary condition that increases the risk of cancer, particularly in the colon and endometrium. Mutations in the mismatch repair genes (MSH2, MLH1, MSH6, and PMS2) increase the risk of LS. Reported PMP cases with hereditary gene mutations of unknown significance are also rare. Here, we investigated a PMP patient and her family members, who have an MSH2 variant of unknown significance. Physicians have an important role in counseling, management, and surveillance based on genetics and pathogenicity.

Pseudomyxoma peritonei (PMP) is a rare clinical syndrome characterized by profuse jelatinous materials in the abdominal cavity and pelvis with mucinous implants on the peritoneal surface. There are some studies for serum tumor markers, including carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 125 (CA125), to assess the risk of recurrence following cytoreductive surgery and intraperitoneal chemotherapy. However, rare cases were reported about recurrence with increasing serum CEA levels. Herein, we report a case of recurrence of PMP according to serially elevated serum CEA.

Mucinous adenocarcinoma of the kidney is an extremely rare cystic malignant tumor with a poor prognosis that occurs in the pelvicalyceal system. Pre-opeartive diagnosis is very difficult because the tumor's clinical and imaging features are nonspecific. Here we report a case of primary mucinous adenocarcinoma arising from the horseshoe kidney in a 69-year-old male, focusing on CT findings. The tumor was a complex cystic mass with irregular wall thickening, multifocal calcifications, and septa and progressed to pseudomyxoma peritonei postoperatively.

Among medical claims review, decision of malignancy is very important. According to the pathologic report may be ordinary pathway. Some tumors are not completely studied especially malignancy. Wheather malignancy or benign is the important thing in medical claims review. We here disscuss on the debatable tumors such as carcinoid tumor, gastrointestinal stromal tumor (GIST), desmoid tumor, MALToma, and pseudomyxoma peritonei. Another controversial subject in the medical claims review is selection of pathologic report. If the result of the pathologic report is not same in one patient, We prefer the selsection of the report from more professional hospital. We have called this professional hospital l as "third hospital" or 'refferal hospital".
