[Meso-omental cystic lymphoma. Considerations apropos of 4 cases]

Cystic meso-omental lymphangiomas are uncommon benign tumors. When symptoms arise, the correct diagnosis is only exceptionally considered. These tumors may be revealed by a variety of clinical pictures which, in fact, are not specific. Cystic meso-omental lymphangiomas are usually diagnosed in pediatric patients, although they may arise in adults. The four patients who are reported on are adults. Diagnosis was established upon histopathological examination of specimens removed during surgery or autopsy. Data from a review of the medical literature provides a basis for a clinical and above all pathological study of cystic meso-omental lymphangiomas. Prognosis is usually favorable although it is dependent upon the conditions of surgical management.
