Distinguishing breast atypia from ductal carcinoma in situ
is important clinically but very challenging for pathologists.
Management of patients diagnosed with lobular carcinoma in situ
at needle core biopsy at a community-based outpatient facility.
The widespread use of mammography in breast screening has also led to increased detection of ductal carcinoma in situ
(DCIS), due to the frequent presence of microcalcifications within the lesions.
Cohort 1 : Carcinoma in situ
patients with or without papillary disease whose cancer was determined to be refractory or recurred within six months of their last course of adequate BCG
 stated that microscopically sarcomatoid urothelial carcinoma contains a urothelial, glandular, or small cell component with variable degrees of differentiation and that carcinoma in situ
is found in 30% of these cases.
Solid papillary ductal carcinoma in situ
versus usual ductal hyperplasia in the breast: a potentially difficult distinction resolved by cytokeratin 5/6.

Treatment costs per patient for KCs, also known as nonmelanoma skin cancers, were $1,456 for basal cell carcinoma (BCC), $1,326 for squamous cell carcinoma (SCC), $1,016 for unspecified, nongenital invasive KCs, $971 for squamous cell carcinoma in situ
, and $906 for genital skin cancer (not shown on graph), reported Jean Yoon, PhD, of Veterans Affairs Palo Alto Health Care System, Menlo Park, Calif., and her associates (Dermatol Surg.
There were 16 cases (25.0%) of different grades of dysplasias along with 11 cases (17.2%) of carcinoma in situ
, seven cases (11.0%) of lichen planus, six cases (9.4%) of erythroplakia, and five cases each (7.8%) of lichenoid dysplasia and submucosal fibrosis.
