    Localized giant pseudopolyposis in ulcerative colitis can mimic cancer, presenting as a palpable mass. This condition, characterized by numerous pseudopolyps, can cause partial obstruction and requires careful diagnosis to differentiate from malignancy.

    Area of Science:

    • Gastroenterology
    • Pathology
    • Radiology

    Background:

    • Ulcerative colitis (UC) is a chronic inflammatory bowel disease.
    • Malignant transformation is a known complication of long-standing UC.
    • Distinguishing UC complications from colorectal cancer is clinically significant.

    Observation:

    • A case presented with a palpable epigastric mass.
    • Imaging revealed a fulminant collection of pseudopolyps causing partial obstruction.
    • The mass effect mimicked a neoplastic tumor.

    Findings:

    • The patient had localized giant pseudopolyposis, a rare manifestation of UC.
    • Pseudopolyps, while benign, can form large masses.
    • The presentation mimicked colorectal carcinoma.

    Implications:

    • Giant pseudopolyposis should be considered in the differential diagnosis of masses in UC patients.
    • Accurate diagnosis is crucial to avoid unnecessary aggressive treatment for cancer.
    • This case highlights the diverse and sometimes misleading presentations of UC complications.
