Radiographic findings of hemolymphangioma in four patients: A case report

Oral Hemangiolymphangioma Presenting As Gingival Enlargement: A Rare Case With Literature Review

Vascular malformations are anomalies that are caused by disturbances in vasculogenesis. Depending upon the dominant structure present histologically, they may be found in different combinations of vascular elements and are named hemangiolymphangioma (HLA) or lymphangiohemangioma (LHA). HLA occurs in multiple anatomical sites, such as the head and neck, axilla, abdominal cavity, extremities, and urinary bladder, but it is infrequent in the oral cavity. An 18-year-old male with a history of abdominal tuberculosis presented with an asymptomatic mandibular gingival swelling that was histologically diagnosed as HLA. A six-month follow-up revealed no recurrence. The observations reported in this case are unusual, and our literature review revealed no previously documented case of gingival HLA.

Extremely rare pediatric primary scrotum tumor: spermatic cord hemolymphangioma for a case report and literature review

Hemolymphangioma is an uncommon benign tumor type that commonly occurs in the head and neck. Primary spermatic cord hemolymphangioma (SCH) with only several reported, however, is extremely rare. Clinical diagnosis can be challenging because of its rarity. Although spermatic cord hemolymphangiomas are benign tumors, there is still a high recurrence rate in postoperative. A 15-year-old boy presented to our hospital with complaints of scrotal for 15 days and did not have other associated symptoms. The male genital color Doppler ultrasound revealed that a cystic echo in the left spermatic cord region and above the testes was about 32 mm × 20 mm × 14 mm. He underwent left en bloc scrotum tumor resection under general anesthesia, and pathologic examination showed SCH. He was discharged from the hospital in the second postoperative day. After 1-month follow-up, the patient recovered well without recurrence. The patient is currently in follow-up phase. Up to date, only a few cases have been reported in the literature about SCH. So, we hope to raise the awareness of the diagnosis of SCH in clinical practice although this case.

Case report: obstruction in the right ventricular outflow tract due to hemolymphangioma

Cardiac masses commonly involve primary tumors, metastatic diseases, and nonbacterial thrombotic and infective endocarditis. myxomas are the most common primary tumors, accounting for 75%. Hemolymphangiomas are a group of congenital vascular and lymphatic malformations that originate from the mesenchyme, with an incidence rate of 0.12%-0.28% per year. Hemolymphangiomas have been found in the rectum, small intestine, spleen, liver, chest wall, and mediastinum but have not yet been reported in the ventricular outflow tract in the heart. Herein, we report a case of a hemolymphangioma tumor in the right ventricular outflow tract (RVOT). The tumor was successfully resected, and the patient was followed up for 18 months and did not exhibit tumor recurrence.

Obscure Gastrointestinal Bleeding Caused by a Small Intestinal Lymphatic-venous Malformation: A Case Report with a Literature Review

A 44-year-old woman presented with severe anemia. We strongly suspected gastrointestinal bleeding; however, esophagogastroduodenoscopy, colonoscopy, and computed tomography showed no bleeding sources. Video capsule endoscopy revealed an actively bleeding submucosal lesion within the jejunum. Double-balloon enteroscopy revealed a 20-mm continuously bleeding submucosal lesion in the distal jejunum. We suspected small intestinal vascular malformation and performed surgical resection. The resected specimen pathologically comprised dilated, thin-walled lymphatic channels and blood vessels involving the small intestinal submucosa. Therefore, the patient was diagnosed with small intestinal lymphatic-venous malformation. Postoperatively, the patient recovered well, and recurrence was not observed.

Resection of a Large Hemorrhagic Mediastinal Lymphangioma in an Adult Patient: A Radiologic-Pathologic Correlation

Lymphangiomas are rare benign lesions resulting from abnormal proliferation and sequestration of lymphatic tissues that are disconnected from the rest of the lymphatic system. This is a case of a 50-year-old woman with an unusually large mediastinal lymphangioma complicated by hemorrhage. The substantial mass effect and unstable clinical status necessitated urgent operative management. The use of preoperative multimodality radiologic assessment, including CT and MRI, is illustrated throughout this case. Keywords: CT, MR Imaging, Thorax, Lung © RSNA, 2022.

Hemolymphangioma with multiple hemangiomas in liver of elderly woman with history of gynecological malignancy: A case report

BACKGROUND

Hepatic hemolymphangioma is an extremely rare benign congenital malformation composed of cystically dilated lymphatic and blood vessels, and they have nonspecific clinical symptoms and laboratory results. In this study, hepatic hemolymphangioma with multiple hemangiomas in an elderly woman was initially reported and analyzed.

CASE SUMMARY

A 61-year-old female patient, with a history of hysterectomy and bilateral adnexectomy, was referred to the hepatobiliary surgery department with the complaint of multiple hepatic hemangiomas that had been diagnosed 2 years prior in a preoperative contrast-enhanced computed tomography (CECT) examination. Upon entering our hospital, no abnormal physical examination and laboratory data were found. The latest CECT revealed a new 7.0 cm × 6.2 cm cystic-solid lesion with multiple internal divisions in segment II of the liver, with delayed CECT enhancement characteristics that presented as solid parts with internal division. On the positron emission tomography (PET)/CT, no significant uptake of ¹⁸F-fluorodeoxyglucse was observed. Finally, hepatic hemolymphangioma was confirmed based on the pathological and immunohistochemical results after surgery. At 1-year follow-up, her posthepatectomy evaluation was uneventful, and she had recovered full activity. In addition, no postoperative recurrent or residual lesion was found on CECT imaging.

CONCLUSION

Hepatic hemolymphangioma with multiple hemangiomas was reported and observed by CECT and PET/CT imaging.

Haemolymphangioma of the small bowel mesentery in adults: two case reports and a literature review

Background

Haemolymphangioma arising from the small bowel and its mesentery is extremely rare in the clinical setting. To date, only 8 cases of small bowel haemolymphangioma have been reported, and there have been no previously reported cases of haemolymphangioma in the small bowel mesentery (PubMed). The formation of this tumour is mostly congenital, but the exact mechanism is still unclear. As a benign tumour, the presentation of the disease may vary from a simple well-defined cystic lesion to an aggressive ill-defined lesion mimicking malignancy. However, there are no typical symptoms, and preoperative diagnosis is difficult.

Case presentation

We present two cases of haemolymphangioma in the small bowel mesentery in a 54-year-old man and a 52-year-old woman. Both of them came to the hospital due to an abdominal mass. In the first case, a cystic teratoma in the left abdominal area was considered after abdominal plain computed tomography (CT) and magnetic resonance imaging (MRI) scans. After taking an enhanced CT scan, a lipoma was considered based on the images. In the second case, cystic masses of the left upper and middle abdomen were observed on abdominal ultrasonography. An abdominal plain CT scan showed an irregular low-density mass in the left upper and middle abdomen. With an enhanced CT scan, haemolymphangioma was considered based on the images. After complete surgical removal, the masses were found to originate from the small bowel mesentery and had not invaded into the peripheral lymphatic tissue. In case 1 in this study, the routine pathology diagnosis was lymphangioma, while in case 2, the diagnosis was haemangioma. The final diagnosis was confirmed to be haemolymphangioma by immunohistochemistry in both cases. No recurrence was evident during 4 months of follow-up. We review the previous case reports of haemolymphangioma in the abdominal cavity and discuss their clinical features, diagnosis, treatment and prognosis.

Conclusions

The clinical manifestations of abdominal haemolymphangiomas can vary for both location and size. Abdominal CT examination has important clinical value for haemolymphangioma in the abdominal cavity. The final diagnosis of haemolymphangioma depends on a postoperative pathological examination. In addition, postoperative regular follow-up is necessary.

Haemorrhagic ileal haemolymphangioma: a case report and review of the literature

We describe herein a 37-year-old woman with a 2-week history of melena who was eventually diagnosed with ileal haemolymphangioma, a rare benign tumour. Local mucosal congestion and swelling were found through single-balloon enteroscopy, which showed an irregular protuberance approximately 10 cm long, located 3.2 m from the Treitz ligament. We performed a laparoscopic-assisted partial resection of the small intestine combined with intestinal adhesiolysis. According to postoperative pathology, the final diagnosis was ileal haemolymphangioma with haemorrhage.
