“…One hypothesis suggests that they are derived from diverticulosis, whereas the other suggests that they are derived from hamartomas: tumor-like malformations or congenital abnormalities of tissue development resulting in abnormal mixtures of tissues normally involved with the biliary tree. 7 The pathogenesis of the adenomyoma found in our patient was more consistent with the latter hypothesis because no diverticulosis was seen in the lesion histologically.…”

Adenomyoma of the Common Hepatic Duct Mimicking Bile Duct Cancer: Report of a Case

et al. 2007

We report an unusual case of adenomyoma of the common hepatic duct mimicking bile duct cancer. A 50-year-old woman was referred to our hospital for the investigation of general fatigue. Laboratory data showed abnormal liver test results and computed tomography showed a mass lesion in the hepatic hilum and dilatation of the intrahepatic bile ducts. These findings led to a preoperative diagnosis of hilar bile duct carcinoma, and we performed a left lobectomy with resection of the extrahepatic bile duct. Macroscopically, an elevated lesion was found in the common hepatic duct, which was confirmed histologically to be an adenomyoma. Bile duct strictures are rarely caused by benign tumors of the biliary tract, such as adenomyoma. Surgical resection of the bile duct should be considered for all bile duct strictures because it is often difficult to differentiate malignant from benign lesions in this location preoperatively, and malignant cells may be present in the lesion.

This paper described a rare case of adenomyoma of common bile duct. The case is a 51-year-old man who was hospitalized for yellow color skin and sclera and itching for 2 mo without abdominal pain. Nothing special was found in physical examination except yellowish skin and sclera. The clinical presentation and Contrast-enhanced magnetic resonance imaging (MRI), Magnetic resonance cholangiopancreatography (MRCP), and ultrasonography suspected a tumor of the distal bile duct. The patient was treated successfully by pancreaticoduodenectomy. Histologically, the lesion consisted of adenoid and myofibrous tissue and moderate atypia. The immunophenotype of the epithelial component was cytokeratin 7+/cytokeratin 20-. The patient has been well without any evidence of recurrence for 12 mo since his operation.

A Case of Adenomyomatous Hyperplasia of the Distal Common Bile Duct Mimicking Malignant Stricture

Adenomyomatous hyperplasia is a reactive malformation or non-neoplastic tumor-like lesion frequently observed in the gallbladder, stomach, duodenum and jejunum, but rare in the extrahepatic bile duct. A 42-year-old man with epigastric discomfort had a stricture in the common bile duct on initial CT scans. Initially, it was regarded as a malignant lesion with some evidence, but histopathologic examinations of multiple biopsies obtained by multiple sessions of endoscopic retrograde cholangiopancreatography showed no evidence of malignancy. The patient had undergone the pylorus preserving pancreaticoduodenectomy because of the possibility of malignancy; however, the final diagnosis was adenomyomatous hyperplasia. It is important to distinguish a malignancy from benign biliary stricture with endoscopic biopsies. Surgery for suspected biliary malignancy often reveals benign lesions. Therefore, a correct diagnosis is important before deciding upon treatment of bile duct stricture. In conclusion, in younger patients with bile duct stricture where there is no evidence of histologic malignancy despite multiple biopsies, the possibility of benign disease such as adenomyomatous hyperplasia should be considered, to avoid unnecessary radical surgery.
