Lymphangioma of the omentum in a 5-year-old child

Lymphangiomas are vascular malformations that occur mainly in childhood. Their etiology is still unknown. In most cases, children arrive with a clinical picture of benign tumor, but there is also an asymptomatic course. The article describes a clinical case of a 5-year-old boy who was admitted to the surgical department of the Children’s Republican Clinical Hospital with a diagnosis of «Volumetric abdominal cavity formation», based on the results of ultrasound examination during periodic health examination. The child was indicated a diagnostic laparoscopy, during which multiple thin-walled cystic formations filled with hemorrhagic fluid were revealed. Due to the difficulties in determining the source of the formations, a decision was made to convert. A transverse laparotomy was performed, followed by total resection of the large omentum. Based on the obtained macropreparation, cytological and general clinical studies, the diagnosis of «Cystic hemlimphangioma of the large omentum» was made. However, the histological picture showed the presence of cystic multicameral lymphangioma. The postoperative period was uneventful. This article describes a rare clinical case of lymphangioma in the large omentum without clinical manifestations, which became an accidental finding during periodic health examination.
