Patients with cytologic atypia were at higher risk of developing dysplasia than those with reparative atypia. Our results support the theory of progression from atypia to dysplasia in a considerable percentage of patients. Cytologic atypia in the contralateral unaffected breast is related to parity and estrogen-related genes. Nevi with architectural disorder and cytologic atypia of melanocytes (NAD), aka "dysplastic nevi," have varying degrees of histologic abnormalities, which can be considered on a spectrum of grades of atypia. Somewhat controversial and subjective criteria have been developed for grading of NAD into three categories "mild," "moderate," and "severe." 2010-03-16 · Cytologic means of the cells (cellular) Atypia means not normal.

Cytologic atypia

Many skin pathologists (dermatopathologists) classify atypical moles or dysplastic nevi as having mild, moderate, or severe atypia. Unfortunately this classification system is very subjective and pathologists looking at the same specimen will often disagree on the level of atypia. Atypical moles, also known as dysplastic nevi, are unusual-looking moles that have irregular features under the microscope. Though benign, they are worth more of your attention because individuals with atypical moles are at increased risk for melanoma, a dangerous skin cancer.

endometriecancer and CIN III (carcinoma in situ) with diffuse atypia and loss of maturation. The cellular clusters derived from the metaplastic lesions lacked atypia but resembled those from gastric mucosa. Those derived from the without cytologic atypia and with circumscribed margins, extensive hyalinization, low mitotic activity, and clear cells are considered benign.

Some benign follicular lesions are hypercellular and even focal cytologic atypia may occur.

Usually, cytologic atypia is of more important clinical concern than architectural atypia. Atypical cells can change back to normal cells if the underlying cause is removed or resolved. This can happen spontaneously. Or it can be the result of a specific treatment. Atypical cells don't necessarily mean you have cancer. However, it's still important to make sure there's no cancer present or that a cancer isn't just starting to develop. Many skin pathologists (dermatopathologists) classify atypical moles or dysplastic nevi as having mild, moderate, or severe atypia.
