Since 2010, there is also a Bethesda system used for cytopathology of thyroid nodules, which is called The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC or BSRTC). Like TBS, it was the result of a conference sponsored by the NIH and is published in book editions (currently by Springer).
Hürthle cells arise from the follicular epithelium. A Hürthle cell is larger than a follicular cell, and polygonal with distinct cell borders. [ 2 ] Key features of these oncocytic cells include a granular cytoplasm that stains eosinophilic (pink on H&E stain ), which is commonly due to the oncocytes' high content of mitochondria , and a ...
LEEP cone biopsy displaying normal cervical epithelium (far left) progressing to borderline koilocytosis, to LSIL, and to HSIL (far right). A squamous intraepithelial lesion (SIL) is an abnormal growth of epithelial cells on the surface of the cervix, commonly called squamous cells.
A further category is used to define cells that do not show significant nuclear abnormality, and may not be described as 'dyskaryotic.' This category is termed [epithelial] cellular "borderline changes". As dyskaryotic epithelium found in the cervix have malignant potential, most cases of dyskaryosis will typically be followed up and referred.
Hürthle cell neoplasm is a rare tumor of the thyroid, typically seen in women between the ages of 70 and 80 years old. When benign, it is called a Hürthle cell adenoma, and when malignant it is called a Hürthle cell carcinoma. Hürthle cell adenoma is characterized by a mass of benign Hürthle cells (Askanazy cells).

Examples of epithelial dysplasia include cervical intraepithelial neoplasia – a disorder commonly detected by an abnormal pap smear) consisting of an increased population of immature (basal-like) cells which are restricted to the mucosal surface, and have not invaded through the basement membrane to the deeper soft tissues.
This system provides a uniform way to describe abnormal epithelial cells and determine specimen quality, thus providing clear guidance for clinical management. These abnormalities were classified as squamous or glandular and then further classified by the stage of dysplasia: atypical cells, mild, moderate, severe, and carcinoma. [13]
VAIN can be detected by the presence of abnormal cells in a Papanicolaou test (Pap smear). [2] Like cervical intraepithelial neoplasia, VAIN comes in three stages, VAIN 1, 2, and 3. [3] In VAIN 1, a third of the thickness of the cells in the vaginal skin are abnormal, while in VAIN 3, the full thickness is affected. [3]
