[Carcinoids of the rectum].

V D Karelin

    Arkhiv Patologii
    |January 1, 1976
    PubMed
    Summary

    Rectal carcinoids show diverse histology, with cellular-alveolar and band-solid variants identified. Invasion and size >2cm indicate malignancy, not lipids or mucus absence.

    Area of Science:

    • Gastroenterology
    • Oncology
    • Pathology

    Context:

    • Rectal carcinoids are rare neuroendocrine tumors.
    • Histological classification is crucial for diagnosis and prognosis.
    • Previous studies have focused on specific subtypes or clinical behaviors.

    Purpose:

    • To investigate the morphological and histological characteristics of rectal carcinoids.
    • To identify potential indicators of malignancy in rectal carcinoids.
    • To differentiate between benign and malignant variants based on histological features.

    Summary:

    • Eight rectal carcinoids were analyzed, revealing two main histological variants: cellular-alveolar and band-solid.
    • Lipids and mucus were present in tumor cells, but argentaffine granulation was consistently absent.
    • Muculent stroma was a common feature in all investigated carcinoids.
    • Malignancy indicators include muscular layer invasion and a size exceeding 2 cm.
    • The presence of fat and mucus, along with the absence of argentaffine granulation, are not definitive proof of malignancy.

    Impact:

    • Provides a detailed histological characterization of rectal carcinoids.
    • Clarifies diagnostic criteria for malignancy in rectal carcinoids.
    • Contributes to improved understanding and management of rectal neuroendocrine tumors.
