Summary
Signet ring-like cells in ascites are rare in primary peritoneal serous tumors. Degeneration of tumor cells may cause cytoplasmic vacuoles, mimicking signet ring morphology in this unique case.
Area of Science:
- Oncology
- Pathology
- Cytology
Background:
- Primary peritoneal serous tumors are uncommon malignancies.
- Signet ring-like cells are typically associated with other tumor types, such as gastric adenocarcinoma.
- The presence of these cells in peritoneal fluid requires careful diagnostic evaluation.
Purpose of the Study:
- To report a unique case of primary peritoneal serous tumor presenting with signet ring-like cells in ascites.
- To discuss the potential mechanisms behind the formation of these signet ring-like cells.
Main Methods:
- Case report.
- Ascitic fluid cytology analysis.
- Histopathological examination of tumor tissue.
Main Results:
- Ascitic fluid revealed numerous signet ring-like tumor cells.
- Primary peritoneal serous tumor was diagnosed.
- Tumor cell degeneration was hypothesized as the cause of cytoplasmic vacuole formation, leading to the signet ring appearance.
Conclusions:
- Signet ring-like cells in ascites can occur in primary peritoneal serous tumors.
- Tumor cell degeneration is a plausible explanation for this cytological finding.
- This case highlights the importance of considering unusual morphologies in peritoneal fluid cytology.
