Summary

Eosinophilic dysplasia of the cervix is recently described unusual and somewhat obscure dysplastic lesion of squamous epithelium. We present histological features of a lesion in 41 years old woman. It was composed of cells with brightly eosinophilic cytoplasm contoured by a sharp and slightly broader cytoplasmic membrane, lacking maturation, with mild increase in nuclear-cytoplasmic ratio, slight chromatin clumping and uneven mild nuclear clearing. Electronmicroscopic study showed mild crevices of the nuclear membrane in some dysplastic cells. Tissue in situ hybridization study confirmed the presence of HPV 6 in the form of patchy dotted pattern of integrated type. Immunohistochemistry revealed diffuse positive expression of antigen p16, extraordinarily in this case focally sparing basal part of the epithelium. Underestimation of this lesion can be avoided by paying attention to strong eosinophilia of the cytoplasm and sharp cellular contouring of the examined epithelium in routine hematoxylin-eosin staining.

Keywords:
