Abstract

Teratoma arising from extrahepatic common ducts is very rare entity. The authors found 2 teratoma cases originating from common bile duct in the literature. As a third case, the authors report on a 4-month-old girl with benign cystic teratoma arising from distal common hepatic bile duct and with anomalous common bile ducts. Surgical management of the patient also is discussed.

Case report

A 4-month-old girl was admitted for progressive jaundice and asymptomatic progressive abdominal distension lasting for a month. His past medical history was unremarkable. The child was observed to be icteric on physical examination. Abdominal examination found a prominent distention and a huge, well-defined mass that was nonfixed with a smooth surface at the right upper and lower quadrants and was passing over to the other side of the midline. The child otherwise appeared well. On laboratory

Discussion

Teratomas are neoplasms containing elements derived from the 3 primary germ layers, and the most common sites for teratoma are sacrococcygeal, mediastinal, and retroperitoneal regions and gonads. Teratomas rarely occur in abdominal organs such as the liver.3, 4, 5, 6 Teratoma of the common bile ducts is an extremely rare entity. We found only 2 case reports of teratoma arising from the common bile duct in the English-language literature.1, 2 There was no morphologic and radiologic description

  • Giant infantile immature teratoma derived from the hepatoduodenal ligament: Report of a case

    2013, Journal of Pediatric Surgery Case Reports
    Citation Excerpt :

    The patient is now carefully followed at the outpatient clinic. Only 10 cases of teratoma originating from the hepatoduodenal ligament have been reported in the English literature (Table 1) [2–10] and our report is the 11th case. Among them, 3 cases were in adults, and only one case was malignant teratoma with a high AFP level whereas 8 out of 10 cases were mature teratoma.

  • Portal teratoma causing obstructive jaundice in children: A rarity

    2012, Journal of Pediatric Surgery
    Citation Excerpt :

    Rare cases of these tumors occurring in the gastrointestinal tract, liver, nasal sinuses, cervix, and thyroid have been reported [6]. Teratoma in the hepatoduodenal ligament is very rare, and we could find only 7 reported cases hitherto after an extensive literature search [1,4,7–10]. Most of the teratomas in children are benign in nature, with excision being the preferred treatment of choice.

  • Mature cystic teratoma arising at the porta hepatis: a diagnostic dilemma

    2008, Journal of Pediatric Surgery
    Citation Excerpt :

    Although present in both gonadal and extragonadal sites, it is more commonly seen in the ovary and sacral region and is often associated with elevation of the alpha-fetoprotein and bHCG [2]. The occurrence of a teratoma in the biliary tree [1,3], porta hepatis, or liver [4,5] is rare. Choledochal cyst is likewise uncommon and will usually be associated with abnormalities of liver function tests and recurring jaundice [6].

  • Immature teratoma of gallbladder associated with gliomatosis peritonei, a case report

    2007, Journal of Pediatric Surgery
    Citation Excerpt :

    The digestive organ as an origin of teratoma is rare. There were some reports of teratomas derived from a digestive organ such as stomach, liver, and extrahepatic common bile duct [1-5]; however, we could not find a case of teratoma of the gallbladder in any literature. Interestingly, our case also had gliomatosis peritonei (GP) on her omentum and peritoneum.
