    Summary

    A rare goblet cell carcinoid tumor was found in the appendix of a 50-year-old man. Further surgery was performed due to the tumor's size and potential malignancy.

    Area of Science:

    • Gastroenterology
    • Surgical Pathology
    • Oncology

    Background:

    • Appendicitis is a common surgical emergency.
    • Carcinoid tumors are a type of neuroendocrine neoplasm, with goblet cell carcinoids being a rare subtype.
    • Early diagnosis and appropriate management are crucial for carcinoid tumors.

    Observation:

    • A 50-year-old male presented with acute appendicitis.
    • Intraoperative findings revealed an inflamed appendix with a gross tumor at the apex.
    • Histologic examination confirmed a goblet cell carcinoid measuring 1.7 cm in diameter.

    Findings:

    • Neoplastic cells showed positive reactions with Grimelius and Masson-Fontana silver stains.
    • Electron microscopy identified endocrine granules within neoplastic cells.
    • The tumor invaded the mesoappendix, indicating a potentially aggressive nature.

    Implications:

    • The size and mesoappendiceal invasion of the goblet cell carcinoid necessitated a further surgical procedure.
    • This case highlights the importance of thorough histopathological examination of appendiceal specimens.
    • Aggressive surgical management, such as ileoascendocolectomy, may be required for larger or invasive goblet cell carcinoids.
