squamous metaplasia

Areas of squamous metaplasia and epithelial pearls may be present.

Common sites for squamous metaplasia include the bladder and cervix.

Smokers often exhibit squamous metaplasia in the linings of their airways.

Vitamin A deficiency can lead to squamous metaplasia.

Vitamin A deficiency has been observed to cause squamous metaplasia in many types of epithelia.

Squamous metaplasia of breast epithelia is known to be more prevalent in postmenopausal women (where it does not cause any problems at all).

Other possible way of SCTC development might be a through the squamous metaplasia.

Infections are characterized by pronounced acute inflammation, squamous metaplasia, blood and reactive epithelial changes.

It is presumed that all bronchogenic squamous dysplasia arises from squamous metaplasia.

In advanced cases, the epithelium undergoes pathologic changes, namely squamous metaplasia and loss of goblet cells.

Other metaplastic entities in the urinary bladder include squamous metaplasia and nephrogenic adenoma.

It has been speculated that either the direct toxic effect or hormonal changes related to smoking could cause squamous metaplasia of lactiferous ducts.

The significance of squamous metaplasia in the development of low grade squamous intraepithelial lesions in young women.

SMOLD is distinct from squamous metaplasia that may occur in papilomatous hyperplasia.

Adolescent girls differ biologically from adult women (e.g., cervical squamous metaplasia) that might increase their susceptibility to either persistent infection or disease (877,901).

Also called Zuska's disease (only nonpuerperal case), is a frequently aseptic inflammation and has been associated with squamous metaplasia of the lactiferous ducts.

Keratinizing squamous metaplasia of lactiferous ducts may play a similar role in the pathogenesis of nonpuerperal subareolar abscess.

Foci of squamous metaplasia and dysplasia may be present in the epithelium proximal to adenocarcinomas, but these are not the precursor lesions for this tumor.

The epithelial cells are usually columnar, but the columnar epthelial cells can undergo apocrine or squamous metaplasia.

Second, there's an abnormally high number of mitotic figures in the stained tissues, and the whole appearance is about halfway between squamous metaplasia and frank neoplasm.

A chemoprevention trial using isotretinoin also employed histologic studies of bronchoscopic biopsies to examine the intermediate endpoint of squamous metaplasia.

APAs are characterized by glands with abnormal shapes that: (1) often have squamous metaplasia, and (2) are surrounded by benign smooth muscle.

Squamous cell carcinoma is a malignant epithelial tumor which originates in epidermis, squamous mucosa or areas of squamous metaplasia.

Further uncertainty in the relation of SMOLD and the subareolar abscess is that squamous metaplasia is very often caused by inflammatory processes.
