Marked atypia of type 2 pneumocytes is a characteristic finding in association with treatment with busulfan and other chemotherapeutic agents.. Atypia (from Greek, a + typos, without type; a condition of being irregular or nonstandard) [1] is a histopathologic term for a structural abnormality in a cell, i.e. it is used to describe atypical cells.
Further it states the need for population based studies including both non-atypical and atypical hyperplasia to accurately estimate the risk of progression to cancer. [8] If untreated with hysterectomy, endometrial hyperplasia progresses to adenocarcinoma within 20 years in: 28% of cases with atypia (95% CI, 8.6% to 42.5%), and
A benign nevus is read as (or understood as) having no cytologic or architectural atypia. An atypical mole is read as having architectural atypia and having (mild, moderate, or severe) cytologic (melanocytic) atypia. [12] Usually, cytologic atypia is of more important clinical concern than architectural atypia.

Koilocytosis or koilocytic atypia or koilocytotic atypia are terms used in histology and cytology to describe the presence of koilocytes in a specimen. [1] Koilocytes may have the following cellular changes: Nuclear enlargement (two to three times normal size). Irregularity of the nuclear membrane contour, creating a wrinkled or raisinoid ...
Nuclear atypia refers to abnormal appearance of cell nuclei. It is a term used in cytopathology and histopathology. Atypical nuclei are often pleomorphic. Nuclear atypia can be seen in reactive changes, pre-neoplastic changes and malignancy. Severe nuclear atypia is, in most cases, considered an indicator of malignancy.
Atypical hyperplasia is a benign (noncancerous) cellular hyperplasia in which cells show some atypia. In this condition, cells look abnormal under a microscope and are increased in number. By organs
