Benign solitary cecal ulcer: a condition that mimics plastron appendicitis.

The benign solitary cecal ulcer is a rare clinical entity that is not usually included in the differential diagnosis of the cecal diseases. The etiology is unknown, and there are no pathognomonic lesions or symptoms. Pre-operative and intra-operative diagnosis is difficult. Definitive diagnosis is generally obtained by histologic evaluation of the surgical specimen after a right hemicolectomy performed for a suspected neoplasm of the cecum. We herein describe a 70-year-old woman with solitary cecal ulcer presenting with abdominal pain, palpable mass on the right lower quadrant and leukocytosis, mimicking plastron appendicitis on initial evaluation.
