In the last nine years we have operated upon six children (eight males and two females) with primary omental pathology. The age of our patients ranged from five to eleven years with the exception of a newborn prenatally diagnosed of lymphangioma. All the remaining children had abdominal pain and right iliac tenderness for an average of two days. All had leukocytosis and left shift. Vomiting and fever were present only in one instance. In no case the mass was palpated preoperatively. The initial diagnosis was acute appendicitis in all cases. A patient suffered, one year after operation, a second acute clinical picture and the omental mass could be revealed [correction of decealed] preoperatively. At operation there was free intraperitoneal fluid in six instances (three times bloody, two times clear and one purulent). Surgical findings (nine operations) were: three omental segmental infarctions (primary in two cases and secondary to torsion in one), three segmental epiploitis in two patients (one acute, one chronic, one secondary to foreign body), two cystic lesions (one lymphangioma, one hydatic cyst) and one benign tumor (fibromatosis).

A case of peritoneal cystic mesothelioma in a 40-yr-old woman is reported. The patient was operated on for signs of acute appendicitis. The lesion was made up of small, multiple, thin-walled cysts and both visceral and parietal layers of the peritoneum in the appendix region were involved. The lesion must be differentiated from other cystic lesions of the abdominal cavity and in particular from the multilocular lymphangioma. The diagnostic role of special techniques, such as immunohistochemistry and electron microscopy, in difficult cases is emphasized.

Lymphangiomas are benign tumors of lymphatic vessels, that are more commonly found in the pediatric age group, and thought to be congenital in nature. They most commonly occur in the region of the neck, but they frequently may be found in the abdominal cavity. In the abdominal cavity, the tumors usually involve the mesentery of the small or large intestines. They are usually asymptomatic but may present with signs and symptoms of intestinal obstruction. The tumors are rare enough to arouse interest whenever a case is encountered. We present a case of lymphangioma of the mesentery of the jejunum in a young adult which clinically mimicked acute appendicitis.

Intra-abdominal lymphangiomas usually present by 2 years of age and are uncommon in adults. Cystic lymphagiomas arising from the lesser sac are even more uncommon. We report an unusual case of a lesser sac cystic lymphangioma presenting as acute appendicitis. A 21 year old female was admitted with pyrexia, right iliac fossa tenderness and an elevated C-reactive protein (CRP). At laparotomy, a large fluid filled cystic lesion was observed occupying the right side of the abdominal cavity. The lesion was excised in its entirety and histological diagnosis confirmed lymphangioma. The patient remains well with no evidence of recurrence 1 year post resection.
