In anatomy, squamous epithelium is epithelium (i.e. tissue found at the outside of the body or at the inside of body cavities) consisting of one or more cell layers, the most superficial of which consisting of flat, scalelike or platelike cells, which are called squamous cells. These surface cells are irregularly shaped and very flat; so flat that the cell nucleus sometimes creates a bump in the surface of the cell. Gases and other substances can easily diffuse across squamous cells, and because of their smooth surface, liquids can quickly flow over them.
One distinguishes between simple squamous epithelium, which consists of a single layer of squamous cells, and stratified squamous epithelium with more than one layer. For example, simple squamous epithelium constitutes the lining of blood vessels (endothelium) and of alveoli in the lung; stratified squamous epithelium makes up the outermost layer of the skin (epidermis) and also lines the esophagus.
Dysplasia (from 'bad form', in greek) is an abnormality in the appearance of cells indicative of an early step towards transformation into a neoplasia. It is therefore a pre-neoplastic or pre-cancerous change. This abnormal growth is restricted to the epithelial layer, not invading into the deeper tissue. Though dysplasia may regress spontaneously, persistent lesions must be removed, either with surgery, chemical burning, heat burning, burning with laser, or freezing (cryotherapy).

Hi there !
The simplest way to explain these two words are like this !
"Dysplasia" means changes in the appearance of the cells . Occurs due to many causes and is a word used to describe biopsy slides by surgical pathologists ! Leave it to the specialist ..he knows the best !
"Koilocytosis" is an abnormality wherein the nuclei of the cells take an abonormal change
in appearance ! Here the nucleus get surrounded by a "clear halo" and are very easily seen in the biopsy slides ! Usually caused by physical irritants or some of the infections due to virus or even early malignancies ! (example : cervical lining epithelium). Maybe more "observation" and "treatment" will be required as per suggested by your specialist !
Best wishes !
