Hand-Assisted Laparoscopic Surgery for a Mesenteric Teratoma

Abstract

The authors report a rare case of mesenteric monodermal teratoma that mimicked an ovarian tumor and was successfully managed with hand-assisted laparoscopic intervention.

Mature cystic teratomas: Relationship between histopathological contents and clinical features

“…[3] Teratomas can occur extragonadal tissues such as lung, mesenter and omentum. [4][5][6] The detection rate of tumor markers is low, although high levels of CA-19.9 are common in MCT cases. [7] MCTs are composed of endodermal, mesodermal and ectodermal derivatives.…”

Benign cystic teratoma of the mesosigmoid: Report of a case

“…Teratoma is the most commonly encountered germ cell tumor [4]. Extragonadal intraperitoneal teratomas are extremely rare, although there are almost 40 reports of teratomas arising from the greater and lesser omentum [4,5,6], and only 22 cases arising from mesentery and mesocolon [3]. The occurrence of mesenteric teratoma in males is less common than in females [3,4].…”

The occurrence of mesenteric teratoma in males is less common than in females [3,4]. These tumors more frequently occur in children than in adults, but rare cases of geriatric patients have also been reported [7][8][9][10][11][12][13][14][15][16][17][18].…”

“…These tumors more frequently occur in children than in adults, but rare cases of geriatric patients have also been reported [7][8][9][10][11][12][13][14][15][16][17][18]. Although cases with multiple masses have been described [14], mesenteric teratomas are usually solitary tumors with a diameter ranging 3-18 cm [12,14,17], located more often in the mesenterium than in the mesocolon [3].…”

“…The most common site of extragonadal teratoma is the sacrococcygeal region followed by neck, mediastinum, central nervous system, paranasal sinuses, liver, uterine cervix, stomach, abdominal wall, omentum and peritoneum [2]. Extragonadal intraperitoneal teratomas, especially those arising from mesentery and mesocolon, are very rare -only 22 cases of such tumors have been published and described in the contemporary literature [3].…”
