Venous hemangioma of the mesoappendix: Report of a case and a brief review of the Japanese literature

Abstract

We present herein the rare case of a 48-year-old man in whom an abdominal mass, revealed by celiotomy to be a solid tumor of the mesoappendix, was histologically diagnosed as having a venous hemangioma. To our knowledge, only 18 cases of mesenteric hemangioma have been reported in Japan, including the present case. However, establishing a correct diagnosis preoperatively is extremely difficult despite advanced imaging techniques. In fact, a mesenteric mass was diagnosed preoperatively in only 3 of these 18 cases. Complete excision with or without bowel resection was performed in 16 cases. Interestingly, the histological diagnosis of all the previous cases was cavernous hemangioma, confirming that this report documents the first case of venous hemangioma of the mesentery in the Japanese literature.

A hemangioma of the sigmoid colon mesentery presenting as a retroperitonealtumor: a case report and review

“…Gastrointestinal hemangiomas can occur in any age group, but are more common in young adults, often in the third decade of life [1,3,4]. No definite sex predilection has been identified [1,2].…”

“…Ultrasound examination usually reveals a solid mass of mixed echogenicity, whereas CTscan additionally provides information concerning the tumor extent, multiplicity, vascularization and involvement of the intestine or other intraabdominal or retroperitoneal structures [22]. Due to a lack of specific signs such as phleboliths, preoperative imaging in the case presented failed to establish the correct diagnosis.…”

“…Nonoperative techniques such as sclerotherapy, cryosurgery or interventional angiography usually result in symptom recurrence and are therefore temporary solutions. Recurrence after complete resection has not been reported [3,25]. …”

“…Summary of the single-case reports on mesenteric hemangiomas published in the literature [2,12,15-17,22,26-36]. …”

Congenital Anomalies and Malformations of the Vasculature

“…Venous hemangiomas have been reported in a variety of sites, including the mediastinum, mesentery, skeletal muscle, and retroperitoneum. [106][107][108][109][110][111] Venous malformations histologically are composed of nodules of irregular venous-type vascular channels that may vary in size. This lobular or grouped arrangement of vessels is helpful for distinguishing these benign from malignant vascular proliferations.…”
