Article
Neonatal hepatitis (NH) and biliary atresia (BA) are the most common causes of cholestasis in infancy. NH is a nonobstructive type of neonatal cholestatic syndrome manifesting with hepatitis. BA is an obstructive inflammatory syndrome of the extrahepatic biliary tract. BA accounts for 40% of cholestasis in infancy, and NH accounts for 10%–15% cases...

Lateral aberrant ectopic thyroid is very rare, comprising only 1%–3% of all the ectopic thyroid tissue. Clinically, these lesions are mistaken for lymph node swelling or metastatic tumour. Primary carcinoma in lateral aberrant ectopic thyroid with normal active native thyroid is very uncommon. We report a case of papillary carcinoma in lateral aber...
