Dumble cystic lymphangioma as an underlying cause of vague abdominal complaints in a 2-year-old girl: case report.

UNLABELLED

Lymphatic malformations (LM) refer to very rare hamartomatous benign lymphatic ectasias with an incidence of 1:250 000. They almost involve children more than adults, and among them, infants under one age are mostly affected. Macrocytic LM is found to be more than 2 cm in diameter or 2×2 cm in volume. The proper treatment for mesenteric LM is complete surgical excision unless there is vital structure involvement.

CASE PRESENTATION

The authors report a mesenteric macrocytic LM in a 2-year-old girl complaining of vague abdominal discomfort and persistent vomiting in which ultrasonography revealed a cystic masse with seromucous components. She then underwent exploratory laparotomy. The operation and the follow-up duration were uneventful.

DISCUSSION

LMs are rare benign lesions of vascular origin with lymphatic differentiation, according to the latest International Society for the Study of Vascular Anomalies (ISSVA 2018). Under light microscopy, these malformations are characterized by their thin-walled endothelium and lymphatic tissue.These mobile lesions are incidentally found or appear with intestinal obstruction or acute abdomen scenarios.

CONCLUSION

Although benign, the LMs have the potential for invasion and recurrence. Thus, the examiner physician must keep such intra-abdominal lesions in mind.
