Case Report
We report a case of transmural florid cystic endosalpingiosis of the colon with tumor-like obstruction in a 90-year-old woman with abdominal distention and obstruction.
Pathological Findings
Colonoscopy examination revealed an obstructive luminal mass. Pathologic examination of the sigmoid colectomy specimen revealed a transmural, florid proliferation of mostly cystically dilated glands that were lined by epithelium that varied from flattened to ciliated tubal-type cells typical of endosalpingiosis. The pathologic diagnosis of florid cystic endosalpingiosis of the colon was made based on characteristic microscopic features and the immunoprofile. To our knowledge, this is only the second reported case in the English literature of this entity presenting as an obstructive colon mass.
