A rare case of a large mesenteric lymphangioma in a 2-year-old child: Case report and review of the literature

INTRODUCTION AND SIGNIFICANCE

Lymphangiomas are benign tumors that are typically found in the neck and armpit region but can also occur in other locations. The clinical presentation varies depending on their location and size, and surgical resection is the primary treatment option.

CASE PRESENTATION

We present the case of a child who presented with a painless and non-obstructing abdominal mass. The mass was diagnosed and underwent complete surgical resection. Subsequent tissue analysis confirmed that the cyst was a lymphangioma.

CLINICAL DISCUSSION

These tumors should be considered in the differential diagnosis of cystic lesions in the abdomen, and the importance of performing complete surgical resection is emphasized.

CONCLUSION

The importance of complete surgical resection for mesenteric lymphangioma must be emphasized. Partial resection or aspiration should not be performed due to the risk of complications associated with these procedures and the increased risk of recurrence.

Efficacy of OK-432 sclerotherapy for different types of lymphangiomas: a review and meta-analysis

OBJECTIVE

This study aims to perform a meta-analysis to figure out the efficacy of OK-432 sclerotherapy between Macrocystic (MAC) lymphangiomas and Microcystic (MIC) lymphangiomas.

METHODS

We conducted a systematic review and meta-analysis to clarify the relationship between OK-432 and lymphangiomas. PubMed and ISI Web of Science were searched from inception to May 2022. Joanna Briggs Institute (JBI) manual was used to evaluate the risk of bias. We calculated pooled Relative Risks (RR) and 95% Confidence Interval (95% CI) using random effects model to evaluate the relations between OK-432 and lymphangiomas.

RESULTS

A total of 11 studies (including 352 cases) about OK-432 sclerotherapy for lymphangioma were included in the current meta-analyses. The results suggested that the efficacy of OK-432 was significantly in MAC lesions than in MIC (RR=1.51, 95% CI 1.298-1.764), with significant moderate degrees of heterogeneity among 11 studies (I2=51.2%, p=0.025). Subgroup analyses suggested that there was significant association in both retrospective studies (RR=1.26, 95% CI 1.03-1.53) and classification (by 1 cm) (RR=1.37, 95% CI 1.04-1.80) were associated with the efficacy of OK-432.

CONCLUSION

To our knowledge, our study represents the first meta-analysis examining the efficacy of OK-432 in the treatment of different types of LMs. However, the regional differences and the age differences of the subjects are the main limitations of this study and should be avoided in further research. Our results suggested that OK-432 sclerotherapy for macrocystic lymphangiomas was more effective.

Lymphangioma of the heart as a rare tumor: A case report

•

Lymphangioma is a rare cardiac tumor.

•

Lymphangiomas are benign in nature.

•

Diagnosis based on imaging techniques is difficult.

•

Surgery may be needed for definitive diagnosis and treatment.

Introduction

Tumors of the heart are uncommon, and lymphangiomas are among the rarest of this group, with very few cases reported. These tumors consist of a benign slow-flow vascular malformation.

Presentation of case

We report a case of a man diagnosed incidentally with a pericardial mass and our surgical approach for its treatment.

Discussion

The pericardial mass of our case had no cleavage plane between the myocardium and the tumor. Because of this, rather than a total resection, with very high operative risk, a biopsy was preferred. The pathology specimen showed a benign tumor and the patient was referred to the cardiologist for regular follow-up.

Conclusion

There is no specific investigation for diagnosing cardiac lymphangiomas, and though benign, they should be considered in the differential diagnosis of other malignant diseases of the mediastinum and definitive pathologic diagnosis is mandatory. Given the increased risk of uncontrolled bleeding related to percutaneous biopsy, the definite diagnosis is usually obtained with open surgical biopsy.

Case Report of Four Different Primary Mesenteric Neoplasms and Review of Literature

INTRODUCTION

It is rare for primary tumors to arise from the mesentery. Lymphangiomas appear as congenital malformations of the lymphatic system or benign neoplasms as a large, thin-walled, often multilocular cyst. Mesenteric infiltration is common and during surgical treatment, adjustment of structures such as the bowel and resection of the spleen may be required. Cystic mesotheliomas are rare, benign tumors that originate from the peritoneal mesothelium and are more common in women. Mesenteric cysts are mostly benign and rare intra-abdominal tumors, and can be seen as occupying a large cyst. Malignant fibrous histiocytoma is a rare pleomorphic sarcoma that is more commonly encountered in men. After the extremities, the second most common areas to be affected are the retroperitoneum and peritoneal cavity.

CASE PRESENTATION

We encountered four cases of different primary mesenteric neoplasms that were operated at the Gazi Yasargil teaching and research hospital, department of general surgery, Diyarbakir, Turkey, between 2013 and 2014. We reviewed these primary mesenteric neoplasms and compared them with previous literature.

CONCLUSIONS

Primary mesenteric tumors are rare and mostly benign tumors. Complete surgical excision is necessary for all tumors and follow-up is necessary after surgery for malignant fibrous histiocytoma due to recurrence.
