Jejunal cavernous lymphangioma

Case report: Submucosal cavernous lymphangioma causing jejuno-jejunal intussusception in an adult

Cavernous lymphangioma often occurs in the head, neck, trunk, and extremities of infants and children, and it is rare to cause a small intestine intussusception in adults. In this case, a 32-year-old woman presented with abdominal pain, vomiting, and a 5 cm × 5 cm abdominal mass on the left side of the abdomen. Laboratory tests showed anemia and CT showed small intestinal intussusception. After conservative treatments, her symptoms disappeared. However, 18F-FDG PET/CT suggested malignancy and her symptoms reappeared after eating something. Segmental jejunal resection was performed and pathology showed submucosal cavernous lymphangioma. At the 1-year follow-up, the patient was asymptomatic. Then this paper reviewed the literature on small intestinal cavernous lymphangioma in adults and found that this is the first English case report of intussusception caused by a jejunal submucosal cavernous lymphangioma in an adult. Current problem is that adult intussusception and intestinal lymphangioma are difficult to diagnose preoperatively. Imaging techniques such as tomography and PET/CT aid in the diagnosis of these benign lesions. Surgical resection was considered to be the required treatment and seems to have had no recurrence in adults according to the literature.

Lymphangioma Cavernosum with a Rare Location

Lympangioma cavernosum in the abdominal cavity is a rare benign tumour. In most cases, such tumours are diagnosed in the oral cavity and neck. The aim of this paper is to present our clinical observations and review of existing literature to draw attention to this disease. A 25-year-old woman was admitted to our department for a symptomatic tumour in the lesser curvature of the stomach. The patient was first operated on as a three-year-old child because the tumour extended from the back wall of the stomach to the gastro-colonic ligament. The medical records showed that it was a benign tumour; however, no diagnosis was specified. No symptoms were observed for 22 years. Currently, the patient is admitted for epigastric pain. Abdominal computed tomography revealed an extensive mass located between the left segments of the liver and the lesser curvature of the stomach. The patient was operated on, and the tumour was completely removed. The patient’s postoperative course was uneventful. Histopathological examination of the lymphangioma cavernosum was performed. Two months after the operation, the patient did not report any complaints.

Laparoscopic Resection for Lymphangioma Originating From Small Intestine: A Case Report

Background

Lymphangioma originating from the small intestinal wall is a very rare finding. There have been only 15 case reports on the disease. Here, we report a case of lymphangioma in the small intestine that was resected laparoscopically. We also provide a literature review.

Case Presentation

A 37-year-old man came to our hospital with a chief complaint of abdominal pain. Physical examination showed mild tenderness in the lower abdomen, but rebound tenderness or guarding was absent. A contrast-enhanced computed tomography scan showed local poor enhancement in distal ileum, suggesting the possibility of mucous necrosis. Conservative therapy was started. On the eighth hospital day, although his abdominal symptoms improved, a follow-up computed tomography scan showed no improvement in the distal ileum lesion. Laparoscopic tumor resection was performed. The patient's postoperative course was unremarkable, and he was discharged on postoperative day 7. The pathologic result of the surgical specimen was lymphangioma of the ileum. The patient is still alive with no sign of recurrence 19 months after surgery.

Conclusion

Lymphangioma originating in the small intestinal wall is a very rare disease. Laparoscopic resection seems to be a preferable method for surgery.

Small intestinal hemolymphangioma treated with enteroscopic injection sclerotherapy: A case report and review of literature

BACKGROUND

Hemolymphangiomas are rare malformations composed of both lymphatic and vascular vessels and are located in the pancreas, spleen, mediastinum, etc. Small intestinal hemolymphangioma is extremely rare and often presents as obscure gastrointestinal bleeding. It is rarely diagnosed correctly before the operation. Endoscopic injection sclerotherapy is usually used as a management of bleeding in esophageal varices and was occasionally reported as a treatment of vascular malformation. The treatment of small intestinal hemolymphangioma with enteroscopic injection sclerotherapy has not been reported.

CASE SUMMARY

A 42-year-old male complained of recurrent episodes of melena and dizziness, fatigue and reduced exercise capacity for more than 2 mo. Gastroduodenoscopy and blood test revealed a gastric ulcer and anemia. Treatment with oral proton-pump inhibitors and iron did not improve symptoms. We then performed a capsule endoscopy and anterograde balloon-assisted enteroscopy and revealed a hemolymphangioma. Considering it is a benign tumor without malignant potential, we performed enteroscopic injection sclerotherapy. He was discharged 4 days later. At follow-up 3 mo later, the melena disappeared. Balloon-assisted enteroscopy revealed an atrophied tumor atrophied and no bleeding. Argon plasma coagulation was applied to the surface of the hemolymphangioma to accelerated healing. When he returned for follow-up 1 year later, anemia was resolved and the tumor had been cured.

CONCLUSION

Balloon-assisted enteroscopy and capsule endoscopy are effective methods for diagnosis of hemolymphangioma. Enteroscopic injection sclerotherapy is an effective treatment.

Jejunal cavernous lymphangioma manifested as gastrointestinal bleeding with hypogammaglobulinemia in adult: A case report and literature review

BACKGROUND

Lymphangioma is a benign lesion that rarely involves the gastrointestinal tract, especially in adults. Small bowel lymphangioma is a rare cause of gastrointestinal bleeding. Here, we report a case of an adult diagnosed with jejunal lymphangioma presenting with melena, anemia and hypogammaglobulinemia. We also summarize and analyze all 23 reported cases from 1961 to 2019, and propose an algorithm for identification and management of small bowel lymphangioma.

CASE SUMMARY

A case of a 29-year-old woman presented with persistent melena and iron-deficiency anemia, accompanied by hypogammaglobulinemia. No lesions were found in the initial workup with esophagogastroduodenoscopy, colonoscopy and computed tomography (CT) enterography. Ultimately, capsule endoscopy and double-balloon enteroscopy revealed a 3 cm × 2 cm primary lesion with intensive white lymphatic dilatatory changes and visible fresh blood stains, accompanied by a small satellite lesion. The patient underwent complete surgical resection of these lesions, and histopathological examination confirmed a diagnosis of cavernous lymphangioma of the jejunum. The patient showed no evidence of disease at the time of this report.

CONCLUSION

We recommend CT, capsule endoscopy and enteroscopy to identify the lesions of lymphangioma. Laparoscopic surgery with histological diagnosis is an ideal curative method.

Surgery of multiple lymphangioma in small bowel: a rare case report of chronic gastrointestinal bleeding

Small bowel lymphangioma is a rare benign tumor of the lymphatic system, characterized by the presence of dilated lymphatic spaces and significant gastrointestinal bleeding. Small bowel lymphangiomas are rare in adults and case reports are few. Lymphangiomas in the jejunum or ileum are extremely rare and account for less than 1% of all lymphangiomas. The case reported herein is of an older patient (70-year-old male) with melena and chronic anemia (hemoglobin count < 5 g/dL) who had small-sized multiple lymphangiomas in his small bowel (jejunum). Surgical resection was performed after failure of treatment by gastroenteroscopy. Final pathological analysis revealed lymphangioma with thrombus and hemorrhage. After surgery, he no longer had decreased hemoglobin count, nor symptoms of anemia and melena. Also, at the last follow-up visit, the patient's hemoglobin count patient was normal and he returned to normal daily functions.

Ileo-ileal intussusception caused by lymphangioma of the small bowel treated by single-incision laparoscopic-assisted ileal resection

Intraabdominal lymphangiomas are uncommon; additionally, those affecting the gastrointestinal tract are rare and account for less than 1% of cases. Intussusception caused by a cystic lymphangioma of the small bowel is extremely rare. The patient was a 20-year-old woman who visited our emergency room with a complaint of abdominal pain. A computed tomography image revealed ileo-ileal intussusception with a leading hypovascular mass measuring 1 cm in a diameter. Single-incision laparoscopic-assisted ileal resection was performed. The surgical specimen consisted of a soft polycystic mass. Macroscopically, a pedunculated polyp with a convolutional pattern was found. Microscopically, the inner surfaces of the cysts were covered with a single layer of endothelial cells. On immunohistochemical examination, the endothelial cells were partially positive for D2-40 and CD34. Smooth muscle cells were also found around the cysts. The lesion was diagnosed as a cystic lymphangioma. Dozens of cases of small bowel lymphangiomas have previously been reported. Of these, cases with intussusception were very rare. This is the first case of small bowel intussusception due to lymphangioma treated by single-incision laparoscopic-assisted surgery.
