    This study reviews seven cases of gastric leiomyosarcoma (LMS) and leiomyoblastoma (LMB), highlighting key differences in presentation and treatment. Maintaining gastric reservoir and avoiding extensive resection are crucial for better patient outcomes.

    Area of Science:

    • Gastroenterology
    • Surgical Oncology
    • Pathology

    Background:

    • Gastric leiomyosarcoma (LMS) and leiomyoblastoma (LMB) are rare mesenchymal tumors of the stomach.
    • Understanding their distinct features is crucial for effective management.

    Purpose of the Study:

    • To analyze the natural history, clinical presentation, diagnostic findings, and treatment of gastric LMS and LMB.
    • To identify differentiating criteria between LMS and LMB.
    • To assess factors influencing long-term patient morbidity.

    Main Methods:

    • Retrospective review of seven patients diagnosed with gastric LMS or LMB between 1970 and 1983.
    • Analysis of clinical, radiological, and histopathological data.
    • Evaluation of surgical treatment modalities and patient outcomes.

    Main Results:

    • Tumor location did not correlate with mucosal ulceration frequency.
    • Endogastric tumors showed higher rates of ulceration compared to exogastric tumors.
    • Histological pattern, cell morphology, and mitotic count were key for differentiating LMS from LMB.

    Conclusions:

    • Histopathological criteria are essential for distinguishing gastric LMS from LMB.
    • Preserving gastric reservoir and avoiding extensive gastrectomy are vital for minimizing long-term morbidity after surgical resection.
