[Renal lymphangiectasia, a rare case of perirenal infiltration]. / La lymphangiectasie rénale, un cas rare d'infiltration périrénale.

Renal lymphangiectasia is a bilateral cystic infiltration of the perirenal and parapelvic space which is caused by the obstruction of the renal lymphatic tissue. To our knowledge only numbers have been reported in the literature. Renal lymphangiectasia usually asymptomatic and incidentally diagnosed has absolutely no effect on the patient outcome. Radiological imaging is typical so that the diagnosis does not need to be confirmed by a cyst punction. The lack of knowledge concerning renal lymphangiectasia make it usually confused with another cause of polycystic renal infiltration, such as the polycystic kidney disease. We report herein a case of renal lymphangiectasia diagnosed incidentally by an abdominal ultrasonography.

[Lymphangioma and lymphangiectasia]. / Lymphangiomes et lymphangiectasies.

Primary thoracic lymphatic diseases are both infrequent and probably under diagnosed. The two major forms are lymphangiomas and lymphangiectasias. Lymphangiomas are focal proliferation of well-differentiated lymphatic vessels. Childhood lymphangiomas may follow embryologic disorders. Adult lymphangiomas are more likely secondary to lymphatic obstruction. When associated with typical CT and MRI features, their surgical resection is not mandatory, whereas in case of diagnostic difficulties or related complications, surgical resection is the rule. Lymphangiectasias are congenital or acquired pathologic lymphatic dilatation from pleura and interlobular septa without any proliferation. These diseases can be limited to one pulmonary lobe, or can involve the whole lymphatic network. In case of communication between the lymphangiectasias and the thoracic duct, symptoms may include chyloptysis, chylothorax, and chylopericardium. Lymphangio MRI allows visualisation of the lymphangiectasis and thoracic duct. Surgical treatment may be required in case of resistance to medical treatment.

A Case of Lymphangiectasia of the Vulva / 대한피부과학회지

Lymphangiectasia is a rsre occurrence, and may be due to an undgrlying disturbance of the lymph flow following surgery or irrediation. We present an unusual case of an extensive lymphangictasia of the vulva following radical abdominal hysterectomy and irradiation for cervical cancer.
