Diabetes mellitus brings together several syndromes, all burdened by a high complexity and with the potential to generate vital impairment. The large number of complications result from the association of high blood glucose level with vascular damage, neuropathy, poor healing and overall increased atherosclerosis process. The clinical manifestation of these complications involves a wide range of manifestations from simple lesions to complex pathology, many of them requiring surgical treatment. Surgical implications of diabetes mellitus include diabetic foot syndrome, soft tissue infections, renal impairment and abdominal pathology.

Mesenteric lymphangioma (ML) is a cystic tumor developed at the base of the mesentery, which occurs frequently in children, rarely in adults, with nonspecific symptoms, often diagnosed late. The diagnosis is made by computer tomography and the curative treatment is the surgical one with good results and with optimal postoperative outcome. A 44-year-old patient for whom mesh surgery for incisional hernia post appendectomy has been performed was admitted to our clinic for non-specific gastrointestinal symptoms for which he has also been investigated multiple times in other services. On the right flank and iliac fossa, a tumor of firm-elastic consistency is detected, relatively well delimited. Computed tomography (CT) describes the lesion as a mesenteric tumor. Intraoperatively, a cystic tumor is detected, which is punctured, the biochemical result highlighting the lymphatic character. The surgical treatment was represented by segmental intestinal resection with entero-enteroanastomosis. No postoperative events were
reported.
