We report two cases of lymphatic malformation derived from the mesentery of the small intestine. (Case 1) A female child aged three years and 4 months was brought to our hospital for sudden abdominal pain. Computed tomography (CT) showed a mesenteric cyst measuring 16 × 9 cm. Laparoscopic resection of the cyst was performed. The histopathological finding revealed that the cyst was a lymphatic malformation of the mesentery of the small intestine. (Case 2) A 17-year-old female who was diagnosed as having an ascending mesenteric cyst seven years ago visited our hospital owing to increasing frequency of abdominal pain. We performed laparoscopic resection of the cyst for relief of the abdominal pain without resection of the intestinal tract. The histopathological analysis revealed that the tumor was a cavernous lymphatic malformation arising from the mesentery of the small intestine. Tumor resection is usually performed for lymphatic malformation arising from the mesentery. Laparoscopic surgery for mesenteric lymphatic malformation is safe with a good field of view and less invasive with a minimal wound.
