Abstract
Purpose: Extraosseous Ewing’s sarcoma (EOE) of the rectum is extremely rare:
only three cases have been reported in the literature and none of these reports
described their imaging findings in detail. Herein, we describe the tumor imaging and
pathological features in detail.
Materials and Methods: We report a case of rectal EOE in a 72-year-old female who
received local excision and was provisionally diagnosed with a rectal submucosal
spindle cell tumor. We used immunohistochemistry, histopathology, and fluorescence
in situ hybridization to characterize the tumor and provide a definitive diagnosis of
EOE.
Results: MRI revealed a well-demarcated submucosal tumor with heterogeneous
enhancement and hemorrhagic foci in rectum. EOE was diagnosed by positive
staining of tumor cells for CD99 and Fli-1 by immunohistochemistry and the presence
of the EWSR1 gene translocation by fluorescence in situ hybridization. Although
the patient underwent radiation treatment and surgery, the tumor recurred after 4
months as revealed by computed tomography and magnetic resonance imaging.
Conclusion: Rectal EOE may present as a rectal submucosal tumor. The understanding
of imaging and histological characteristics of this tumor are critical for accurate
diagnosis and appropriate aggressive treatment.
