Pyogenic granuloma of the small intestine

Clinical and Endoscopic Characteristics of Pyogenic Granuloma in the Small Intestine: A Case Series with Literature Review

Pyogenic granuloma (PG) generally appears in the skin or oral cavity, but rarely occurs in the small intestine, where it can cause bleeding. To date, only 35 cases of small intestinal PG have been reported in the English literature. We retrospectively collected information from the clinical records of seven cases of small intestinal PG that were managed in our hospital and summarized the characteristics. Further information on the clinical characteristics was obtained from the literature. Capsule endoscopy, useful for identifying the source of hemorrhage in obscure gastrointestinal bleeding, can detect PGs. Treatment can often be accomplished with endoscopic mucosal resection.

Pyogenic granuloma in the jejunum successfully removed by single-balloon enteroscopy

Pyogenic granuloma is a non-infectious and non-granulomatous lesion. Its location in the small bowel is very rare. We present a 46 year-old woman with a chronic liver disorder that had a severe chronic anemia with occult blood losses. Upper endoscopy and colonoscopy were normal. A small bowel capsule endoscopy showed a pyogenic granuloma in jejunum that was resected endoscopically with single balloon enteroscopy with no major complications. The patient recovered from anemia and six months latter capsule endoscopy did not show lesions.

Gastrointestinal Pyogenic Granuloma (Lobular Capillary Hemangioma): An Underrecognized Entity Causing Iron Deficiency Anemia

Pyogenic granuloma (PG), more accurately known as lobular capillary hemangioma, is a benign vascular tumor that usually occurs in the skin or oral mucosa. This lesion is rarely reported in the gastrointestinal tract but is known to bleed if not resected. We herein describe a case series with the clinical, endoscopic, and histologic findings of four cases of gastrointestinal PG at our institution. In addition, we provide a review of the literature and summation of all reported cases of PG specific to the gastrointestinal tract. Based on our experience, we suggest that the actual incidence of gastrointestinal PG may in fact be higher than reported because PG can be unrecognized or improperly diagnosed. It is important for the clinician to properly recognize this lesion as a source of anemia and its propensity to bleed during biopsy or resection.

Rare cause of severe anemia due to pyogenic granuloma in the jejunum

BACKGROUND

Pyogenic granuloma (PG) is a polypoid lobular capillary hemangioma rarely observed in the gastrointestinal tract. Only a few cases in the small bowel have been described in the literature.

CASE PRESENTATION

A 58-year-old man had been suffering from general fatigue and severe anemia. Esophagogastroduodenoscopy and colonoscopy did not reveal any significant bleeding. Abdominal computer tomography revealed a hypervascular tumor in the small intestine. Oral double-balloon endoscopy (DBE) detected a polypoid lesion (2 cm in diameter) in the jejunum. We performed laparoscopic-assisted partial resection of the jejunum. The histological features of the tumor were consistent with PG. The patient's anemia gradually improved without the need for oral iron after surgery.

CONCLUSION

In this case report, we present a case of pyogenic granuloma in in the jejunum that was detected by DBE.

Obscure gastrointestinal bleeding: resection of a pyogenic granuloma of the ileum via double-balloon enteroscopy

Pyogenic granulomas usually occur on the skin or oral mucosa; however, they rarely develop in the gastrointestinal tract, particularly in the ileum. We report the case of an 82-year-old female who experienced occasional bloody stools. Initially, no significant bleeding source could be identified via conventional endoscopy; however, repeat capsule endoscopy identified a bleeding polyp (8 mm) in the ileum. Therefore, we resected the polyp via double-balloon enteroscopy. Histopathological findings showed increased, lobulated, and enlarged capillaries and desquamated epithelium indicative of epithelial erosion. In addition, neutrophil-predominant inflammatory cell infiltrate and interstitial edema were observed in the intercapillary stroma. Immunohistochemical analysis showed positive staining for vascular endothelial cell markers. Previous reports have mentioned that pyogenic granulomas in the oral cavity were associated with the female hormonal receptor, vascular endothelial growth factor, and proliferative immune markers; however, no significant staining was observed in our patient. This is the first report discussing an association between pyogenic granulomas and these markers. Pyogenic granulomas in the ileum are rare and may cause fatal anemia. Pyogenic granulomas should be considered in the differential diagnosis of obscure gastrointestinal bleeding.

Pyogenic granuloma of the ileum diagnosed by double-balloon enteroscopy

A pyogenic granuloma (PG) is a capillary hemangioma that usually occurs on the skin or in the oral cavity; it is rarely observed in the gastrointestinal tract. We herein describe a case of a 86-year-old woman who presented with anemia. Esophagogastroduodenoscopy and colonoscopy did not reveal any significant bleeding focus, but capsule endoscopy revealed a bleeding focus in the small intestine. We performed double-balloon enteroscopy and identified a 7-mm-diameter, reddish, subpedunculated, hemispheric polyp with a smooth surface in the small intestine, approximately 100 cm from the ileocecal valve. The polyp was surgically removed, and the histological findings were consistent with a diagnosis of PG.

Management of rectal pyogenic granuloma with transanal mucosal sleeve resection

In children, pyogenic granulomas are most commonly cutaneous benign vascular lesions but can also present in the gastrointestinal tract. When they occur in the intestine, they can cause acute or chronic gastrointestinal bleeding. We present an unusual case of rectal pyogenic granuloma and our management strategy.

Pyogenic granuloma: an unusual cause of massive gastrointestinal bleeding from the small bowel

Small bowel hemorrhage is responsible for approximately 4% of all cases of gastrointestinal bleeding. The etiology of bleeding from the small bowel is a tumour in approximately 10% of cases. Pyogenic granuloma is a common inflammatory vascular tumour of the dermis, which rarely occurs in the gastrointestinal tract. Pyogenic granuloma is a rare cause of overt or obscure small bowel bleeding. The present paper reports the first case of pyogenic granuloma presenting as a massive gastrointestinal bleed, and reviews the relevant literature to date regarding the clinical presentation, diagnosis and management of this rare gastrointestinal lesion.
