Abstract:
Pyogenic granulomas are lobular capillary hemangiomas, usually found on skin and oral mucosa. To date, few cases of pyogenic granuloma of the gastrointestinal tract have been reported, being duodenal involvement extremely rare. We report the case of a patient with a history of long-standing iron deficiency anemia where the endoscopy revealed an oozing redish semipedunculated polypoid lesion in the duodenum with a biopsy specimen consistent with a pyogenic granuloma. The lesion was removed by endoscopic resection, and during the follow-up hemoglobin level was maintained.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...
