[Double gastric leiomyosarcoma revealed by a hemoperitoneum]
Insights
This case study details a rare instance of double gastric leiomyosarcoma presenting with hemoperitoneum. The patient later developed hepatic metastases, highlighting the aggressive nature of this rare gastric cancer.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Leiomyosarcoma is a rare malignant mesenchymal tumor.
- Gastric leiomyosarcomas are uncommon, and multiple primary sites are exceedingly rare.
- Presentation with hemoperitoneum indicates advanced disease.
Observation:
- A patient presented with hemoperitoneum due to two distinct gastric tumors.
- Tumors were located in the gastric antrum and cardia.
- One tumor was encapsulated, while the other had a necrotized core.
Findings:
- Pathological examination confirmed leiomyosarcomatosis with double gastric localization.
- The patient developed hepatic metastases five years post-gastrectomy.
- Literature review was conducted on this rare condition.
Implications:
- This case underscores the importance of thorough pathological examination for rare gastric tumors.
- It highlights the potential for late metastatic spread in gastric leiomyosarcoma.
- Further research into the management of multifocal gastric leiomyosarcoma is warranted.
Abstract:
The authors report a complicated leiomyosarcoma gastric case with hemoperitoneum. The exploratory laparotomy reveals an hemoperitoneum constituted from both gastric tumors. One was localised in the antrum and was encapsulated, the other in the cardia and had an encephaloid and necrotized core. The pathological examination of the total gastrectomy piece is consistent with a double gastric localisation of a leiomyosarcomosis. 5 years after the initial operation, the patient developed hepatic metastases. A review of literature allows the authors to make the point of this disease.
