Images of micro-histopathology for H&E samples (with stain) (scale bar: 100 μm). SCC of the oral cavity areas (namely gingival and lower lip) indicates of dissymmetry among squamous cells; black circles are vascular invasion with abnormally sized cells with eminent red nucleoli (showed as yellow circles), pleomorphic big cells (related to yellow arrows), atypical mitotic effects, and some minor nucleoli. Panel a is gingival-related SCC, b is lower lip SCC related to the group of short-term khat users, c is gingival-related SCC, and d is lower lip SCC from the group of long-term khat users
