This report details the first known case of gastric adenosarcoma, a rare biphasic neoplasm, surgically removed from a male patient. The tumor exhibited benign glands within a sarcomatous stroma, with concerning prognostic indicators identified.

Area of Science:

  • Gastroenterology and Oncology
  • Surgical Pathology

Background:

  • Adenosarcoma is a rare biphasic tumor typically found in the female genital tract.
  • Primary gastric adenosarcoma is exceptionally rare, with limited documented cases.

Observation:

  • A case of primary gastric adenosarcoma in a 46-year-old man is presented.
  • The tumor displayed benign glands dispersed within a sarcomatous stromal component.
  • Immunohistochemistry revealed cytokeratin in epithelial elements and vimentin/desmin in stromal elements.

Findings:

  • The gastric adenosarcoma was surgically resected.
  • High mitotic rate in the sarcomatous component and serosal infiltration were noted.
  • Accurate prediction of biologic behavior remains challenging.

Implications:

  • This case expands the known spectrum of adenosarcoma presentation.
  • Understanding prognostic factors is crucial for managing this rare gastric neoplasm.
  • Further research may clarify the behavior and treatment of gastric adenosarcomas.
