Abstract
A desmoplastic small round cell tumor (DSRCT) presented in a 13-year-old female with an acute abdomen due to torsion of a fallopian tube cyst. She was found to have an incidental 2 cm pedunculated, solid, and multicystic mass attached to the pelvic floor on laparoscopy. The neoplasm had a variably myxoid and spindle cell pattern with nests and cords of small cells, forming pseudocysts, and true cysts lined by ciliated epithelium which were PAX-8+ and ER+/PR+. The tumor had the EWSR1::WT1 fusion. Numerous peritoneal nodules less than 1 cm were noted on repeat laparoscopy 3 months later. These had similar features including the ciliated epithelial cysts. Our case illustrates yet another potential variant pattern of DSRCT with Mullerian-like ciliated epithelial cysts.
期刊介绍：
The Journal covers the spectrum of disorders of early development (including embryology, placentology, and teratology), gestational and perinatal diseases, and all diseases of childhood. Studies may be in any field of experimental, anatomic, or clinical pathology, including molecular pathology. Case reports are published only if they provide new insights into disease mechanisms or new information.
