Systematic review links the prevalence of intraductal carcinoma
of the prostate to prostate cancer risk categories.
The examination of the much larger surgical specimen revealed that, although the bulk of the tumor represented high-grade osteosarcoma (99% of tumor volume), the presence of adjacent foci of infiltrating ductal carcinoma and highgrade intraductal carcinoma
indicated that the tumor was much more likely to be a metaplastic ductal carcinoma with osteosarcomatous differentiation than a primary extraskeletal mammary osteosarcoma.
18.) The pure form of these tumors shows no signs of invasion, but in about 75% of cases, intraductal carcinoma
also is found. If the tumor exhibits any signs of invading adjacent tissue, it usually is classified as a nonpure form of mucinous breast cancer and is treated differently than pure mucinous breast cancer.
HGPIN should not be confused with intraductal carcinoma
. The latter, even when isolated in a prostate biopsy, carries a predictive value of 100% for cancer in a repeat biopsy.
She underwent operation left breast excision with axillary dissection because of intraductal carcinoma
(comedocarcinoma) and fibrocystic disease in 1996.

of the prostate metastatic to the penile urethra: A rare demonstration of two morphologic patterns of tumor growth.
In situ intraductal carcinoma
of the breast was used as a c-erbB-2 positive control and negative controls were obtained by the omission of the primary antibody.
Study patients included 24 women with intraductal carcinoma
, 15 women with mucinous carcinoma, 5 women with in situ lobular carcinoma, 2 women with medullary carcinoma, and 14 women with breast diseases but no evidence of cancer.
Conversely, common premalignant and malignant cribriform lesions include high-grade prostatic intraepithelial neoplasia (HGPIN) and the cribriform pattern of invasive acinar adenocarcinoma (Gleason pattern 4), respectively, and less common entities, though still clinically important, are ductal adenocarcinoma and intraductal carcinoma
of the prostate (IDC-P).
Histological reports proved all (100%) to be intraductal carcinoma
. Of the 13 patients, 9 (69%) patients were subjected to modified radical mastectomy, 6(46%) patients received adjuvant chemotherapy of the 6, 3(50%) received CEF, 2(33%) received CAF with Paclitaxel and 1(17%) received paclitaxel with trastuzumab, 3(23%) received adjuvant radiation and 8(62%) received adjuvant hormonal therapy with tamoxifen (Figure 4).
of the prostate is a very important malignant condition with cribriform pattern, given its association with worse prognosis requiring prompt definitive treatment.
