Case Report and Literature Review of Metastatic Gastric Leiomyosarcoma

A figshare document by Ping Chen, last updated May 2026, details a rare case of gastric metastasis from a primary popliteal fossa leiomyosarcoma. The report describes a 60-year-old female patient's presentation, diagnosis via imaging and immunohistochemistry, and multidisciplinary management. The document includes a literature review on the topic of gastric metastases, which are noted to account for only 0.2%–0.7% of gastric malignancies.

Use Cases

• Study the clinical presentation of rare gastric metastases based on the detailed case description.
• Review diagnostic criteria for metastatic leiomyosarcoma based on the reported pathology and immunohistochemistry findings.
• Analyze treatment outcomes for metastatic soft tissue sarcoma based on the reported surgical and chemotherapy regimen.
• Investigate the epidemiology of gastric metastases based on the cited incidence rate of 0.2%–0.7%.

Strengths

• Provides a detailed, peer-reviewed case report of a previously unreported metastasis type.
• Includes specific clinical data points, such as patient age (60), follow-up duration (9 months), and immunohistochemistry markers (SMA+/Desmin+, CD117–/DOG-1–).
• Cites a specific incidence statistic for gastric metastases (0.2%–0.7%).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is a single case report document (694 KB), representing a very limited scope.
