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.
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.
Individual cellular features of dysplasia are called epithelial atypia. [ 2 ] 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 ...
Inherited dysplastic nevus syndrome is an autosomal dominant hereditary condition. Dysplastic nevi are more likely to undergo malignant transformation when they occur among members of melanoma families. At least one study indicates a cumulative lifetime risk of nearly 100% in individuals who have dysplastic nevi and are members of melanoma ...
However, this case had almost moderate atypia with somewhat enlarged vesicular nuclei in the periphery, and therefore immunohistochemistry was performed that confirmed UDH: - Estrogen receptor showing heterogeneous positivity, rather than the diffusely positive expression seen in atypical ductal hyperplasia (ADH)
Losing the dark. Light pollution, the term for the brightening of the night sky by unnatural lights, is increasing worldwide. On average, skies are getting 10% brighter each year globally, with ...
Atypical pneumonia, also known as walking pneumonia, [1] is any type of pneumonia not caused by one of the pathogens most commonly associated with the disease. Its clinical presentation contrasts to that of "typical" pneumonia. A variety of microorganisms can cause it. When it develops independently from another disease, it is called primary ...
