Malignant mesotheliomas may be classified into epithelioid (60%), sarcomatoid (20%), or mixed (20%) type microscopically. Malignant deciduoid mesothelioma, a rare phenotype of epithelioid mesothelioma, arises more commonly from the peritoneum of young women, but is also from the pleura of elderly people. In the current report, the authors describe an unusual case of peritoneal malignant epithelioid mesothelioma with rare deciduoid phenotype demonstrated with 67Ga SPECT/CT.
