BACKGROUND
This report describes the clinicopathologic findings of six hepatic masses that developed after Kasai hepatic portoenterostomy (HPE) in six patients with longstanding biliary atresia (BA).
METHODS
Hepatic masses were found in six of 55 pediatric patients who underwent liver transplantation for BA after Kasai HPE from 1997 to 2009. Clinicopathologic analysis was performed and immunohistochemical staining was carried out for CD34, smooth muscle actin (SMA) and cytokeratin 7.
RESULTS
Of the six hepatic masses, two were diagnosed as focal nodular hyperplasia (FNH)-like lesions, two were large regenerative nodules (LRN), one was a mesenchymal hamartoma (MH) and one was a cholangiocarcinoma. The immunohistochemical staining findings for SMA and CD34 were more prominent for the FNH-like nodules than for the cirrhotic background liver. Dysplastic biliary epithelium arising from intestinal metaplasia was found in the cholangiocarcinoma.
CONCLUSIONS
Our findings suggest that FNH-like lesions, LRNs and MH are the results of vascular hemodynamic changes after Kasai HPE and that cholangiocarcinoma is due to recurrent cholangitis after BA. All the lesions in this series must be included in the differential diagnosis of a newly formed hepatic mass in patients after portoenterostomy.

Abstract PDF: BACKGROUND
Surgical resection of the involved lung for nontuberculous mycobacteria (NTM) has become an important curative therapy. However, there is limited information on the histopathological features of NTM pulmonary disease in Korean patients with NTM infection.
METHODS
We evaluated 51 specimens from 49 patients who were treated at our referral center from 2002 to 2009.
RESULTS
Almost all the cases showed bronchiectasis with lymphocytic infiltration. Variable features of granulomatous inflammation were found; well-defined granulomas in the parenchyma (68.6%), pneumonia-like granulomatous lesions (49.0%) and granulomatous inflammation in the bronchial wall (41.2%) were identified. The microscopic findings of cavitary lesions (37.3%) showed that these lesions were composed of granulomas and necrosis.
CONCLUSIONS
The differentiation of tuberculosis from NTM could not be accurately made based solely on the histological features. However, the airway centered tendency of NTM reflected an airborn etiology, and this could be correlated with the classification according to the radiological findings. In addition, coexisting constitutional lung diseases, and especially bronchiectasis, were suspected to be predisposing conditions for NTM organisms to colonize and progress to true NTM pulmonary disease.

Abstract PDF: Solitary pulmonary lymphangiomas are extremely rare. We report here on an unique case of solitary pulmonary lymphangioma in an adult. A well-circumscribed, 6 cm-sized, pleural based lesion with fluid attenuation was found in a 50-year-old Korean male. He had no previous history of disease or trauma. The wedge-resected lung revealed an ill-demarcated lesion with multiple microscopic cysts and the cystic walls had loose intervening stroma.
