[Glandular-squamous cell stomach cancer].

V I Rottenberg

    Arkhiv Patologii
    |January 1, 1987
    PubMed
    Summary

    Adenosquamous carcinoma of the stomach, a rare cancer, presents without distinct macroscopic features. Microscopic analysis reveals a mix of squamous and glandular cells, suggesting a common origin from multipotent gastric cells.

    Area of Science:

    • Gastroenterology
    • Oncology
    • Pathology

    Context:

    • Adenosquamous carcinoma is a rare gastric malignancy.
    • This study examines five cases diagnosed between 1952 and 1985.
    • These cases represent 0.15% of surgical interventions during the period.

    Purpose:

    • To present and analyze five cases of adenosquamous carcinoma of the stomach.
    • To investigate the microscopic and electron-microscopic features of this rare tumor.
    • To explore the potential cellular origin of adenosquamous carcinoma.

    Summary:

    • Five cases of adenosquamous carcinoma in the stomach body and pyloric antrum were identified.
    • Macroscopic and clinical presentations were indistinguishable from common adenocarcinoma.
    • Microscopic examination revealed a combination of squamous cell and glandular cancer components with varying differentiation.
    • Electron microscopy showed signs of squamous differentiation in gastric carcinoma, with some cells exhibiting both glandular and squamous elements.
    • Findings suggest a common origin from multipotent cambial cells of the gastric mucosa.

    Impact:

    • Highlights the rarity and diagnostic challenges of gastric adenosquamous carcinoma.
    • Provides insights into the cellular origins and differentiation pathways of gastric tumors.
    • Contributes to the understanding of gastric cancer heterogeneity.
