Nuclear atypia 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.

- Atypia of undetermined significance or follicular lesion of undetermined significance where the cytologic findings were not convincingly benign, yet the degree of cellular or architectural atypia was insufficient for an interpretation of follicular neoplasm, Hurthle cell neoplasm, or suspicious for malignancy.

Definitions &Translations Hypoplasia. Hypoplasia is underdevelopment or incomplete development of a tissue or organ. Although the term is not always used precisely, it properly refers to an inadequate or below-normal number of cells. Hypoplasia is similar to aplasia, but less severe. It is technically not the opposite of hyperplasia. Hypoplasia is a congenital condition, while hyperplasia generally refers to excessive cell growth later in life. Hypoplasia can be present in any tissue or organ.

Hypoplasia Hypoplasia (from ancient Greek ὑπo-hypo- , under + πλάσις plasis, formation; adjective form hypoplastic) is underdevelopment or incomplete development of a tissue or organ. Although the term is not always used precisely, it properly refers to an inadequate or below-normal number of cells. Hypoplasia is similar to aplasia, but less severe. It is technically not the opposite of hyperplasia (too many cells). Hypoplasia is a congenital condition, while hyperplasia generally refers to excessive cell growth later in life. (Atrophy, the wasting away of already existing cells, is technically the direct opposite of both hyperplasia and hypertrophy.). Hypoplasia can be present in any tissue or organ.

- Enamel hypoplasia is a defect in the enamel due to. disturbance of ameloblastic function during amelogenesis. The etiology of such a disturbance may be either genetic or. environmental in nature. This case report of undetected. congenital idiopathic hypoparathyroidism emphasizes the. importance of investigating the underlying cause of these. enamel defects. Introduction. Enamel hypoplasia is a defect in enamel that arises. from a disturbance of ameloblastic function during. amelogenesis and is characterized by a reduction in. enamel thickness.
