The term dysplasia is typically used when the cellular abnormality is restricted to the originating tissue, as in the case of an early, in-situ neoplasm. [ citation needed ] Dysplasia, in which cell maturation and differentiation are delayed, can be contrasted with metaplasia , in which cells of one mature, differentiated type are replaced by ...
These terms are related since they represent three stages in the progression of many malignant tumors of the epithelium. The likelihood of the development to cancer is related to the degree of dysplasia. [11] Dysplasia is the earliest form of precancerous lesion which pathologists can recognize in a pap smear or in a biopsy. Dysplasia can be ...
Dysplasia can affect all three lineages seen in the bone marrow. The best way to diagnose dysplasia is by morphology and special stains used on the bone marrow aspirate and peripheral blood smear. Dysplasia in the myeloid series is defined by: Granulocytic series [citation needed]:
Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory disease of the blood vessels that causes abnormal growth within the wall of an artery. [1] FMD has been found in nearly every arterial bed in the body, although the most commonly affected are the renal and carotid arteries.
Cervical intraepithelial neoplasia (CIN), also known as cervical dysplasia, is the abnormal growth of cells on the surface of the cervix that could potentially lead to cervical cancer. [1] More specifically, CIN refers to the potentially precancerous transformation of cells of the cervix.
Bronchopulmonary dysplasia (BPD; part of the spectrum of chronic lung disease of infancy) is a chronic lung disease which affects premature infants. Premature (preterm) infants who require treatment with supplemental oxygen or require long-term oxygen are at a higher risk. [ 1 ]
Diagnosis of Ectodermal Dysplasia is usually made based on the episodes of hyperpyrexia, absence or maturity of sweat glands, absence or type of hair, or the absence and morphology of the teeth [1]. Clinical diagnosis however, is often difficult during early infancy as the above-mentioned manifestations are hard to detect.
Cleidocranial dysostosis (CCD), also called cleidocranial dysplasia, is a birth defect that mostly affects the bones and teeth. [1] The collarbones are typically either poorly developed or absent, which allows the shoulders to be brought close together. [ 1 ]
