Angiolipoma of the duodenum diagnosed after endoscopic resection

Colon angiolipoma with intussusception resected by laparoscopy-assisted surgery: a case report

Angiolipomas are benign mesenchymal tumors that often occur under the skin of the upper extremity or thoracic and abdominal walls. Angiolipomas of the digestive tract are rare. Here, we describe a case of transverse colon angiolipoma with intussusception resected by laparoscopy-assisted surgery. A 50-year-old woman visited a family hospital with complaints of left lower abdominal pain and bloody stool. Colonoscopy revealed a submucosal tumor in her left colon. She was referred to our hospital for further examination. Computed tomography revealed a low-density tumor with intussusception in the left transverse colon. Elective surgery was planned for this patient because there were no alarming symptoms such as ileus or obstruction. Laparoscopy-assisted surgery and partial resection of the left transverse colon were performed. The histopathological diagnosis was angiolipoma of the colon. Angiolipomas are benign mesenchymal tumors that rarely occur in the digestive tract. Thus, accurate preoperative diagnosis is difficult.

Rare localization of angiolipoma in the gastrointestinal tract: a case series

Objective

Angiolipoma is a benign tumor that rarely occurs in the gastrointestinal (GI) tract. This case series was performed to increase clinicians’ understanding of the diagnosis and management of GI angiolipoma.

Methods

We evaluated the clinical presentations, diagnoses, and treatments of 3 patients with angiolipoma in the upper GI tract in our hospital and 27 cases reported in the literature.

Results

Among all 30 cases of GI angiolipoma, 2 originated in the esophagus, 4 in the stomach, 2 in the duodenum, 1 in the jejunum, 7 in the ileum, 1 in the cecum, 9 in the colon, 2 in the rectum, and 2 in both the duodenum and colon.

Conclusion

Angiolipoma of the GI tract may be more likely to occur in middle-aged and elderly men and be located in the ileum and colon. The clinical manifestations generally involve upper GI hemorrhage and lower GI pain and obstruction. Computed tomography and endoscopy may be effective diagnostic techniques, but postoperative histopathologic examination is still the gold standard. The management of angiolipoma in the GI tract depends on the size and type of lesion. Most cases in the present series were managed by complete surgical resection, after which no recurrence was found.

Gastric Angiolipoma Resected with Endoscopic Submucosal Dissection

Angiolipoma is a benign fatty neoplasm that has components of proliferating blood vessels. These types of lesions commonly occur in the subcutaneous tissue of the limbs and trunk. Angiolipoma in the gastrointestinal tract is extremely rare, and the final diagnosis generally depends on histological examination of the excised biopsy. In most previously reported cases, the lesions were diagnosed and treated with surgical management. In this study, we report a case of gastric angiolipoma of approximately 4 cm in size that was diagnosed and treated with endoscopic submucosal dissection.

Multiple gastric angiolipomas: A case report

BACKGROUND

Angiolipoma is a benign tumor and is generally found in subcutaneous tissues. Angiolipomas are rare in the gastrointestinal tract, including the stomach. Preoperative diagnosis of the tumor is difficult, although there are several radiological examinations such as computed tomography and endoscopic ultrasound.

CASE SUMMARY

We report a 24-year-old Chinese man with multiple gastric angiolipomas, with a positive stool occult blood examination. Endoscopic biopsy only showed nonspecific inflammation. Histological examination of the specimen by endoscopic snare resection showed that the tumor consisted of adipose tissues and blood vessels. We also performed a literature review. After the use of proton pump inhibitor, the fecal occult blood test was negative. Due to the difficulty of resecting multiple lesions in the stomach completely and the benign characteristics of angiolipoma, we chose to have regular upper gastrointestinal endoscopy evaluation of the lesion. No evidence of significant change in lesion size was detected after 3-years follow-up.

CONCLUSION

Gastric angiolipoma is rare, and benign neoplasm should be considered when lesions occur submucosally in the gastrointestinal tract.

Gastric Angiolipoma: A Rare Entity

Angiolipoma is a benign tumor composed of adipose tissue and proliferating blood vessels that is commonly found in the subcutaneous tissue of the trunk and extremities. Gastric angiolipoma is a rare entity, and to the best of our knowledge, only 4 cases have been reported in the English-language literature thus far. These tumors may present as gastrointestinal bleeding and anemia or with obstructive symptoms. Accurate preoperative diagnosis is challenging because of nonspecific clinical symptoms and lack of specific findings on imaging studies. The correct diagnosis is usually made by histopathologic examination. The clinical significance lies in being aware of this rare entity in the stomach and distinguishing it from other benign and malignant gastric neoplasms that may be in the differential diagnosis. We herein discuss the clinical presentation, radiologic and histopathologic features, ancillary studies, differential diagnosis, and treatment and prognosis of this rare entity.

Rare case of adult jejunojejunal intussusception secondary to angiolipoma

A woman in her mid-50s presented with a 3-month history of upper abdominal pain. Initial examination using ultrasound was unremarkable and the patient was sent home. The patient returned 8 days later and CT imaging revealed intussusception as the cause of her symptoms. The involved bowel was surgically reduced and transected with the lead point found to contain a 3 cm mass. Histological examination revealed the mass to be an angiolipoma. To the best of our knowledge, this is the first reported case of adult jejunojejunal intussusception secondary to angiolipoma.

Angiolipoma of the stomach presenting with anaemia. Prz Gastroenterol. 2014;9:371-374. [PMID: 25653734 PMCID: PMC4300344 DOI: 10.5114/pg.2014.47498]

Angiolipoma is a morphological variation of the lipoma and is a benign tumour that consists of mature adipose tissue and proliferating blood vessels. It occurs very rarely in the digestive tract, especially the stomach. We report a gastric angiolipoma in a 58-year-old woman admitted for anaemia and melena. Endoscopy showed a large polypoid mass with superficial ulceration in the anterior wall of the gastric antrum. Endoscopic ultrasound showed an about 2 cm sized isoechoic lesion at the third echo layer, with the echogenic portion on the luminal side of the lesion. Laparoscopic wedge resection was performed and histological examination showed that the lesion had encapsulated adipose tissue at the submucosal layer and stromal fibrosis just below superficial ulceration. There were blood vessels with thick walls among the mature fat cells. Therefore, the lesion was diagnosed as an angiolipoma.

Angiolipofibroma of the cecum: a rare type of submucosal polyp

Mesenchymal type tumors originated in the submucosa represent a small percentage of colorectal polyps. This is particularly true for polyps composed of more than one mesenchymal tissue type. We herein present the pathological features of an unusual polypoid proliferation of mature fatty, fibrous, and vascular tissues including vessels of diverse nature and size. The histological findings support a hamartomatous rather than a true neoplastic origin for this rare lesion.

Colon angiolipoma with intussusception: a case report and literature review

Angiolipomas are frequently observed benign tumors. They have a typical vascular component and are often located in subcutaneous tissues, and more rarely, in the gastrointestinal tract. We present the case of a 58-year-old man who complained of abdominal discomfort in the left lower quadrant and two to three bloody stools a day without any obvious etiology. These symptom became more severe in the next three days, due to a large angiolipoma located in the descending colon, which was diagnosed intraoperatively. In a literature review, we found only 22 cases of angiolipomas involving the gastrointestinal tract which are reported in the literature from 1960 to 2012 in PubMed; the key words used in the search are gastrointestinal tract angiolipoma, esophagus, stomach, duodenum, intestine, ileocecal junction, colon, rectum angiolipomas. Colon angiolipoma with intussusception, as seen in this case, is rare and may require emergent surgical intervention.

Ileal intussusception secondary to both lipoma and angiolipoma: a case report

Lipoma and angiolipoma are common benign neoplasms that occur in the subcutaneous tissue and rarely in the gastrointestinal tract. These tumors are usually asymptomatic but may present with abdominal pain, bleeding and obstruction. We present a 53-years-old woman with abdominal discomfort for several weeks accompanied with bloody diarrhea and recurrent vomiting. Ileo-ileal invagination was diagnosed by computed tomography scan. Laparotomy revealed five intraluminal masses that caused intussusception. Histopathological study showed that one was angiolipoma and other lesions were lipoma. We have described some aspects of diagnosis and treatment of this rare cause of intestinal intussusception.

Rare ileal localisation of angiolipoma presenting as chronic haemorrhage and severe anaemia: a case report

Introduction

Angiolipomas are frequently observed benign tumours. They have a typical vascular component and are often located in subcutaneous tissues, and more rarely, in the gastrointestinal tract.

Case presentation

We report an uncommon case of an angiolipoma found in the lower portion of the small bowel of an 80-year-old man who was undergoing evaluation for chronic anaemia. A standardised diagnostic pathway was followed. Endoscopic and radiological findings were negative. The diagnosis was finally established with the aid of capsule endoscopy. The case we report is the first in the literature of an angiolipoma without specific painful symptoms. In fact, the patient did not complain of abdominal pain or alvus changes, and abdominal examination did not suggest an expansive process. The endoscopic study performed with the capsule identified the lesion as the cause of the ingravescent anaemia. Intra-operative histological examination of the lesion made it possible to avoid a major surgical procedure and assured a short postoperative course for the patient.

Conclusion

This report focuses on the importance of correct pre- and/or intra-operative histological diagnosis in order to offer the best therapeutic choice. An angiolipoma was suspected in this case, even though they are rarely located in the ileum.

Rectal angiolipoma: A case report and review of literature

Angiolipoma is a rare vascular variant of the benign lipomatous tumors and is generally seen in subcutaneous tissues. We report a 70-year-old female with abdominal distension not related to rectal small polypoid mass with peduncule described as angiolipoma by histologically, and review the literature.

Rectal angiolipoma diagnosed after surgical resection: A case report

Angiolipoma is a common benign tumor with a characteristic vascular component that usually occurs in subcutaneous tissue. Although lipomas are frequently encountered at colonoscopy as submucosal tumors, angiolipomas are rarely found in the gastrointestinal tract including the large intestine. Here we report a 77-year old Japanese man who underwent transanal resection of a tumor that was diagnosed tentatively as a leiomyoma. Histologically, the tumor consisted of mature fat cells and blood vessels. Immunohistochemically, the tumor cells were negative for c-kit and HMB-45, which are consistently expressed in tumors such as gastrointestinal stromal tumor and angiomyolipoma. The tumor was therefore diagnosed as an angiolipoma. This is thought to be the first case report of a surgically resected angiolipoma of the rectum.
