Organizing mucinous ascitis masquerading as pseudomyxoma peritonei: a process possibly caused by metaplasia but not neoplasia.

摘要: Mucinous ascitis can be differentiated from the more ominous condition pseudomyxoma peritonei microscopically by absence of epithelial cells amidst mucin pools in former. Herein we communicate a brief report organizing mucinous 34-year-old woman, with recurrent abdominal pain localized to right iliac fossa. Imaging studies were suggestive mucocele. Conservative management, followed appendicectomy and enbloc removal surrounding adhesions, was performed. Histopathology revealed chronic obliterative appendicitis, along presence pools, mixed inflammatory reactive mesothelial peri-appendiceal tissue. There an morphologically well-defined, neoplastic pool, thus excluding diagnosis peritonei. The problem cells, which at places look like solved panel immunohistochemistry. possibly have originated metaplasia lining peritoneum, secondary attacks appendicitis.
