Light micrograph of a cervical smear,graded CIN 3 (severe dysplasia) showing a mass of fibre-shaped cells with elongated,cigar-shaped nuclei. The CIN grading refers to a spectrum of potentially cancerous changes (dysplasia) in the stratified squamous epithelium that lines the cervix. CIN 1 corresponds to mild dysplasia,CIN 2 to moderate dysplasia & CIN 3 to severe dysplasia & carcinoma- in-situ. In a normal squamous epithelium,cell division is confined to the basal layer; cells mature & rise towards the surface. Normal superficial cells are pink staining,with small nuclei. Dysplastic cells represent a disruption in the maturation process | |
