Special techniques for example morphometry, DNA ploidy and immunohistochemical studies against various antigens are used to differentiate premalignant lesions like fibrocystic disease with epitheliosis
, atypical ductal hyperplasia, atypical lobular hyperplasia, sclerosing adenosis and carcinoma in situ.
17) Some examples of nipple adenoma show entrapped, compressed ducts, typical of infiltrating epitheliosis.
The terms have been used to encompass papillary lesions that have unusual clinical or imaging presentations, those with florid UDH, those with infiltrating epitheliosis, those with superimposed low-grade in situ mammary neoplasia, or those with low-grade malignant papillary neoplasms (see Table 3).
The sclerotic central zone frequently shows infiltrating epitheliosis and, when that is present, some authors refer to the entire lesion as infiltrating epitheliosis.
Epitheliosis, infiltrating epitheliosis, and radial scar.
, apocrine metaplasia, pseudo angiomatous stromal hyperplasia, atrophy and cystically dilated ducts were among the major microscopic features observed.
A diagnosis of mucinous ductal epitheliosis
of the pancreas was considered and she was offered surgery as this was a premalignant condition.
Our studies are meant to investigate the distribution of Cdc25B in the duodenal mucosa of chicken, and compare it with the expression pattern of Cdc25B in adult tissues of mammals, providing some molecular evidences at the gene level that could elucidate the regular pattern of avian intestinal tract epitheliosis
and functional partition.
17] It sometimes is referred to as epitheliosis
, a name that relates to papillary proliferation of the ductal epithelium.
One false negative case was reported cytologically as ductal epitheliosis and histopathologically proved malignant resulting in the negative predictive value of 97.
One case reported cytologically as ductal epitheliosis was histopathologically IDC schirrous type with DCIS.
of the breast: an immunohistochemical characterization and comparison to malignant intraductal proliferations of the breast.
