ASTRACT. We have studied the microscopic features of buccal epithelium in smoking students of Indo-Dravidian race. In the epithelial cells of the mucous cheek surface of smoking students we revealed the scored nuclei with tongue-and broken egg-type protrusions, micronuclei, cellular dimorphism, binuclear cells, as well as a significant decrease in nuclear-cytoplasmic ratio, as compared to the control, which may indicate the presence of local inflammation resulting from the toxic effects of smoking products on the oral mucosa.

Extrapulmonary tuberculosis, constitutes almost one-fifth of all tuberculosis cases and less than 1% of all cases involving liver. Here we report a case of isolated hepatic tuberculoma mimicking solitary liver mass on MRI, recovered with anti-TB treatment. The radiologic features of hepatic tuberculoma can mimic liver tumors, cholangiocarcinomas, liver abscess and hydatid cyst, or may present with various forms of systemic diseases. The physical findings and imaging appearance of hepatic tuberculoma are considered to be nonspecific on US, CT and MRI that may cause diagnostic problems. For the accurate diagnosis of atypical liver lesions mimicing mass at radiologic imaging, a histopathological or bacteriological confirmation is often required.
