[Cystic lymphangioma with endosalpingiosis as a rare cause of gastrointestinal bleeding].

We report on a 31-year-old woman with an iron-deficiency anemia and positive Guaiac test, existing for more than 2 years. Despite an extensive gastrointestinal examination a bleeding source could not be found. Also angiography of the abdominal arteries with injection of heparin as provocative protocol was normal. Enteroclysis showed a remarkable finding which led to laparotomy. A cystic lymphangioma with endolymphatic endosalpingiosis as the bleeding source was identified and removed. Lymphangioma is a rare benign soft tissue tumor which usually appears during the first 2 years of life. Only in some cases the lymphangioma is intraabdominal and there can be different, no specific symptoms. Endosalpingiosis is also a rare benign disease, it consists of scattered epithelium of the Fallopian tube. It is the first case to our knowledge, in which the appearance of the endosalpingiosis in a lymphangioma is described.
