Solitary hepatic lymphangioma - a case report

Abstract

Hepatic lymphangioma is an extremely rare benign neoplasm that is usually associated with lymphangiomas of other viscera. We report a patient with huge, solitary hepatic lymphangioma involving only the liver. The clinical features and computed tomography findings of this case are described.

Solitary hepatic lymphangioma: Report of a case

“…Solitary hepatic lymphangioma is an extremely rare tumor, and only 8 cases, including the one presented here, have so far been reported in the English literature [7][8][9][10][11][12] (Table 1). Four cases in children were accompanied by acute symptoms, and each tumor was very large (average diameter about 17 cm).…”

“…2 The occurrence of solitary lymphangioma in the liver is extremely rare, and only 7 reports have appeared in the English literature. [7][8][9][10][11][12] Unfortunately, none of these reports provided details of the clinicopathological fi ndings and immunohistochemical characteristics.…”

Solitary hepatic lymphangioma in a 22-day-old infant

“…Reports of lymphangiomas solely involving the liver are extremely rare [7,8]. Most of the reported cases are in older children and adults [3,7,9]. To our knowledge, the previous youngest patient and only infant with a solitary hepatic lymphangioma reported in literature was aged 4 months [10].…”

“…Solitary hepatic lymphangioma is an extremely rare benign neoplasm characterized by cystic dilatation of the lymphatic vessels in the hepatic parenchyma. Lymphangiomas of the liver may occur in isolation or in association with lymphangiomas of other viscera [3]. They are congenital malformations of the lymphatic system, considered as areas of localized lymphatic stasis due to blockage of regional lymphatic drainage [4].…”

Uncommon Etiology of a Cystic Hepatic Tumor

“…It is usually associated with lymphangiomas of other viscera. It could result from a developmental defect in the lymphatic vessels or in its communication with the venous system [2,3] . Surgical excision is recommended [3] .…”
