Colorectal pyogenic granuloma is a relatively rare disease. Here, we report a case of cecal pyogenic granuloma that required differentiation from neuroendocrine tumor (NET). A 72-year-old man was referred to our hospital because of fecal occult blood. Colorectal endoscopy revealed a polyp-like lesion on the ileocecal valve. Enhanced computed tomography and magnetic resonance imaging showed rich blood flow in the tumor, but somatostatin receptor scintigraphy showed absent accumulation of the isotope; therefore, it was not possible to make a definitive diagnosis. Laparoscopic-assisted ileocecal resection was performed as a diagnostic surgery. The postoperative pathologic diagnosis was pyogenic granuloma of the cecum.
Pyogenic granuloma of the large intestine that requires differentiation from NETs is rare. Our case indicates the importance of differentiating this disease when a blood-rich tumor is found in the large intestine.
