Abstract

Desmoplastic small round cell tumor (DSRCT) is a rare aggressive malignant tumor. It is a refractory tumor and the median overall survival is very short. We report two autopsy cases of DSRCT, both of which were already advanced and metastasized at the first medical examination. Both cases showed typical DSRCT findings in terms of localization of the lesions, histopathology and genetics, but the rate of disease progression was quite different. Survival after initial symptoms in Case 1 was only 12 months. On the other hand, survival after primary hospitalization in Case 2 was 42 months. The Case 2 patient initially received chemotherapy for advanced pancreatic carcinoma, because a nodule of the pancreatic tail was found on computed tomography (CT) scan. After chemotherapy, tumor regression was observed on CT scan. It is thus implied that adoption of the regimen for pancreatic carcinoma might have been one of reasons of the long survival in Case 2.
