    • Abstract

    Background
    Lymphangioma usually occurs in the head and neck area. We present a very rare case of cystic lymphangioma that originated from the diaphragm. Few cases were reported in the literature.

    Methods
    A 69-year-old woman was referred to our hospital for macrocytic anemia and weight loss. Pernicious anemia was diagnosed by the presence of the atrophic gastritis, the decreased serum vitamin B12 level, and the anti-parietal cell antibodies and anti-intrinsic factor antibodies in blood serum. In addition, on chest computed tomography (CT) she was found to have a multicystic mass, measuring 50 mm in diameter, which seemed located in the anterior mediastinum and abdominal cavity, across the diaphragm. The cranial part of the mass consisted of solid structure including fat components but no calcification, and the caudal part consisted of multicystic structure, of which septal wall was slightly enhanced. The mass did not appear to invade the liver but to compress. Fluorine-18-fluorodeoxyglucose positron emission tomography (PET) scan showed no abnormal uptake. The mass was suspected a cystic teratoma, a bronchial cyst, a lipoma, a thymoma, or Morgagni hernia. It was resected through right diagonal thoraco-laparotomy with short upper midline incision.

    Results
    Seen from intrathoracic side the mass did not invade the pericardium and seemed to have firm adhesion to the diaphragm, and from intraabdominal side did not perforate the peritoneum or invade the liver, and no hernia canal was seen. The mass was not able to apart from the diaphragm, and combined resection of the diaphragm was performed. Pathologically it was diagnosed as a lymphangioma.

    Conclusion
    Lymphangioma arising from diaphragm is a very rare tumor. It should be considered in the differential diagnosis of diaphragm tumor.
