Pseudomyxoma peritonei of ovarian origin--an autopsy case.
The autopsy case of an 80-year-old female with pseudomyxoma peritonei arising in the left ovary is reported. The patient was admitted with complaints of anorexia, sense of fullness and abdominal distension of two months' duration, and died of intestinal obstruction four months later. The autopsy revealed extensive tumor dissemination over the entire peritoneal cavity without any visceral invasion or distant metastasis. A part of the sigmoid colon showed marked stenosis and perforation with abscess formation. Histologically, the tumor was composed of various sized multiple cysts which were completely or incompletely lined by a layer of mucin-producing columnar epithelial cells with moderate nuclear hyperchromatism, and of a papillary pattern in some parts, indicating low grade malignancy.
