Hepatocellular carcinoma may develop from multistep carcinogenesis via dysplastic nodules in the cirrhotic liver. The first stage between high-grade dysplastic nodule to overt hepatocellular carcinoma is vaguely nodular, early hepatocellular carcinoma. The consensus on the nomenclature and pathologic characteristics of both entities were recently established by an international consensus group ...

Agenesis of the gallbladder is a rare anomaly that is usually asymptomatic, but sometimes the patients may have symptoms compatible with a biliary disorder like cholelithiasis. Its preoperative diagnosis is often difficult, especially if dysplastic cyst is associated and simulates the gallbladder. When the diagnosis is doubtful its confirmation and treatment of dysplastic cyst require open surg...

Most colorectal cancers arise from dysplastic lesions, such as adenomatous polyps, and these lesions are difficult to be detected by the current endoscopic screening approaches. Here, we present the use of an intrinsic second-harmonic generation (SHG) signal as a novel means to differentiate between normal and dysplastic human colonic tissues. We find that the SHG signal can quantitatively iden...

Orthotopic multicystic dysplastic kidney with crossed fused ectopia is a rare congenital anomaly. This congenital anomaly may give an appearance of a solitary kidney morphology during the initial imaging evaluation. A solitary kidney should be carefully evaluated for the presence of duplication, horseshoe configuration, or crossed renal ectopy. Vesicoureteral reflux is a common finding associat...

Bony hand anomalies in patients of pulmonary stenosis are very rare. CASE REPORT A 50-year-old lady, with no significant past history, presented with slowly progressive breathlessness and fatigue, and had progressed from NYHA class 1 to 2 over 2 years...
