“…Ewing sarcomas, rhabdomyosarcomas (predominantly embryonal), and desmoplastic small round cell tumors have been described as maintaining SRBCT morphology, although in some illustrations, the cells have appreciable cytoplasm imparting a more epithelioid appearance. In addition, some cases have shown remarkable cohesion . We also found that most SRBCTs kept their SRBCT appearance; however, most cases had loosely to tightly cohesive clusters of malignant cells, and a few cases showed a more epithelioid cell morphology because of increased cytoplasm.…”

Background Sarcomas are uncommon findings in body cavity fluids. Diagnosis may be challenging because sarcoma cells in fluids can round up and lose their characteristic appearance seen on smears and histologic sections. This study characterizes the cytologic features of sarcomas involving body cavity fluids. Methods Effusion fluids and cerebrospinal fluids diagnosed as positive for sarcoma were reviewed. Results Forty‐three fluids from 28 patients (median age, 47 years) were positive for sarcoma. Four patients who presented with positive fluids were alive at 1 to 10.7 years' follow‐up (median, 22.5 months). Twenty‐four patients died 2 days to 2 years (median, 19 days) after their positive fluid diagnoses. Twenty‐eight specimens from 20 patients had slides available for review. Although 18 of the 28 positive fluids had a morphology comparable to that of their primary, 4 small round blue cell tumors (SRBCTs) and 4 spindle cell tumors showed epithelioid morphology, 1 SRBCT had pleomorphic morphology, and 1 epithelioid primary had SRBCT morphology. Nine fluids had tumor cells in large, cohesive clusters mimicking carcinoma; workup was performed for 10, predominantly to rule out carcinoma and mesothelioma. Conclusions Sarcoma morphology may be altered in exfoliated cytology specimens. Workup on cell blocks aids in the differential diagnosis, especially for carcinoma and mesothelioma. Unsurprisingly, fluid cytology positive for sarcoma portends poor survival.

“…Rhabdomyosarcoma presenting in effusion cytology specimens is an uncommon but well described event . Typically, the cells of rhabdomyosarcoma present in effusion specimens as dyshesive individual cells with scant cytoplasm which has been described as a small round blue cell tumor.…”
