Objective: To evaluate the morphological and immunohistochemical features of infiltrating epitheliosis and its differential diagnosis. Methods: Nine consultation and routine cases of infiltrating epitheliosis diagnosed from January 2015 to December 2016 in Fudan University Shanghai Cancer Center were collected. All tissues were formalin-fixed paraffin-embedded and routinely HE stained. The HE slides were reviewed. Immunohistochemical staining of CKpan, CK7, CK19, CK5/6, CK14, p63, SMMHC, Calponin, ER, PR, HER2, Ki-67 and S-100 protein was performed using Ventana BenchMark automated immunostainer...

Out of a total of 50 study-eligible patients, 15 patients were found to have synchronous breast cancer and gallbladder diseases. Fourteen such patients had breast cancer and cholelithiasis while 1 patient had breast cancer with gallbladder cancer. Amongst these 15 patients, 7 patients tested positive for chromosomal aberrations on karyotyping. Aberrations in these patients were seen on chromosomes 13 and 17 with 2 patients having deletion 13q, 2 having deletion 17q, and 2 having deletions on 17p while one patient had multiple deletions on chromosomes 13q and 17p...

Ductal carcinoma in situ (DCIS), invasive breast cancer (IBC) and lympho-vascular invasion (LVI) represent distinct stages in breast cancer progression with different clinical implications. Altered microRNA (miRNA) expression may play a role in mediating the progression of DCIS to IBC and LVI. The aim of this pilot study was to investigate whether differential miRNA expression could play a role in breast cancer progression. Cancer cells from DCIS, IBC and LVI were microdissected from formalin fixed paraffin embedded (FFPE) tissue of five breast cancer samples...

BACKGROUND: For left-sided pancreatic ductal adenocarcinoma (PDAC), radical antegrade modular pancreatosplenectomy (RAMPS) is a reasonable surgical approach for tumor-free margin resection and systemic lymph node clearance. In pancreaticoduodenectomy for PDAC, the superior mesenteric artery (SMA)-first approach (or the "artery-first approach") has become the standard procedure. With improvements in laparoscopic instruments and techniques, some surgeons attempted to apply laparoscopic RAMPS (L-RAMPS) for carefully selected patients with left-sided PDAC...

Despite the significant biological, behavioural and management differences between ductal carcinoma in situ (DCIS) and invasive carcinoma of the breast, they share many morphological and molecular similarities. Differentiation of these two different lesions in breast pathological diagnosis is typically based on the presence of an intact barrier between the malignant epithelial cells and stroma, namely the myoepithelial cell (MEC) layer and surrounding basement membrane (BM). Despite being robust diagnostic criteria, the identification of MECs and BM to differentiate in situ from invasive carcinoma is not always straightforward...

Non-mammary metastases involving breast are rare and most commonly involve the breast parenchyma. Infrequently, metastasis from an extramammary primary site presents as inflammatory carcinoma over the breast. Diagnosis of such lesions can be challenging, especially in patients with co-existing primary breast carcinoma. Few such cases have been described in literature; however, none of the previously reported cases had a prior history of primary breast carcinoma. We present two patients with history of breast carcinoma and serous carcinoma of ovarian/peritoneal origin that presented with inflammatory carcinoma over the breast...

Some pancreatic neuroendocrine tumors (P-NETs) are associated with hereditary syndromes. An association between Lynch syndrome (LS) and P-NETs has been suggested, however it has not been confirmed to date. We describe the first case associating LS and P-NETs. Here we report a 65-year-old woman who in the past 20 years presented two colorectal carcinomas (CRC) endometrial carcinoma (EC), infiltrating ductal breast carcinoma, small intestine adenocarcinoma, two non-functioning P-NETs and sebomatricoma. With the exception of one P-NET, all these conditions were associated with LS, as confirmed by immunohistochemistry (IHC) and polymerase chain reaction (PCR)...

The coexistence of two or more tumours in the same patient is unusual, but even rarer is the metastasis of one tumour to another. Most reports are based on evidence from autopsies; very few refer to surgical specimens. The most common primary tumour is pulmonary carcinoma and most frequent metastatic tumour is renal clear cell carcinoma. We present the case of a 54 year-old female with a past history of infiltrating ductal carcinoma of the breast with metastases in lung, lymph nodes and bone. Three months previously to her referral to us, she had developed a renal mass and underwent nephrectomy...

Toll-like receptor 5 (TLR5) plays a fundamental role in immune responses. Recent findings suggest the TLR5 expression level affects cancer progression and development. In the present study, our examination of 256 breast carcinomas specimens revealed that TLR5 is overexpressed in breast carcinomas, and that TLR5 overexpression correlated with lymph node metastasis and cancer grade (p<0.01). In a case-control study, we also analyzed associations between TLR5 single nucleotide polymorphisms (SNPs) and breast cancer risk...

Heterogeneous patterns of mutations and RNA expression have been well documented in invasive cancers. However, technological challenges have limited the ability to study heterogeneity of protein expression. This is particularly true for pre-invasive lesions such as ductal carcinoma in situ of the breast. Cell-level heterogeneity in ductal carcinoma in situ was analyzed in a single 5 μm tissue section using a multiplexed immunofluorescence analysis of 11 disease-related markers (EGFR, HER2, HER4, S6, pmTOR, CD44v6, SLC7A5 and CD10, CD4, CD8 and CD20, plus pan-cytokeratin, pan-cadherin, DAPI, and Na+K+ATPase for cell segmentation)...

RATIONALE: Treatment of breast cancer during pregnancy (BCP) remains a challenge to physicians. Surgery and chemotherapy during pregnancy are widely used for the treatment of BCP. Herein, we reported 3 Chinese patients with BCP who underwent chemotherapy during pregnancy and were followed up for adverse effects. PATIENT CONCERNS: Three female patients (case 1, case 2, and case 3) of 37-, 32-, and 28-year-old with breast masses were enrolled. Case 1 had been pregnant for over 4 months, case 2 over 7 months, and case 3 for 7 months...

Epithelial-myoepithelial carcinoma (EMC) is a malignant salivary gland neoplasm comprised of a biphasic arrangement of inner luminal ductal cells and outer myoepithelial cells. Adenoid cystic carcinoma (AdCC) is also a biphasic tumor comprised of ductal and myoepithelial cells, but these components tend to be arranged in a more cribriform pattern. The occurrence of "hybrid carcinomas" that show mixed patterns of EMC and AdCC raises questions about the relationship of these morphologically overlapping but clinically distinct tumors...

Invasive ductal carcinomas of breast with marked stromal lymphocytic infiltration have come to be classified as lymphocyte predominant breast cancer (LPBC) because it obtains high pathological complete response rates with neoadjuvant chemotherapy. Medullary carcinoma (MC), which is independent from LPBC, is a rare histological subtype of invasive breast carcinoma accompanied by abundant lymphoplasmacytic infiltration as LPBC. Although MC shows marked cellular and structural atypia, it usually has a favorable outcome...

Neuroendocrine carcinoma (NEC) of the breast is a rare disease and has been scarcely reported by African authors. The authors report a case of breast NEC in a 13-year-old African girl initially diagnosed as an atypical adenofibroma by ultrasonography. Ultrasound-guided biopsy and conventional histological examination indicated two potential diagnoses: primary malignant non-Hodgkin's lymphoma and undifferentiated carcinoma. According to immunohistochemistry performed on paraffin blocks in France, infiltrating ductal carcinoma with a strong neuroendocrine component was confirmed by CD56, CD57, and chromogranin A markers...

Objectives: Programmed death ligand 1 (PD-L1) expression in pancreatic ductal adenocarcinoma (PDA) has been described, but unselected PDAs have shown limited clinical responsiveness to anti-programmed death 1 (PD-1)/PD-L1 therapy. Methods: We studied 24 cases of undifferentiated pancreatic carcinoma (UPC) using immunohistochemistry for PD-L1 (E1L3N clone), CD3, CD20, CD68, and DNA mismatch repair proteins in this study. Slides were scored for extent of PD-L1 expression on tumor cells and tumor-infiltrating immune cells...

Ductal or lobular carcinoma in situ (DCIS/LCIS) can rarely arise from sclerosing adenosis (SA). The combination of cytologically malignant cells and the infiltrative growth pattern may make it challenging to distinguish it from an invasive carcinoma. The authors reviewed 50 consecutive cases of CIS involving SA to seek the salient histologic characteristics in order to prevent overdiagnosis. The features commonly seen with CIS were the lobular configuration at low magnification (94%), uninvolved SA in neighboring tissue (84%), at least focally identifiable myoepithelial cells on H&E-stained sections (76%), separate foci of unequivocal CIS (58%), associated microcalcifications (54%), and hyaline basement membrane surrounding tumor cell nests (48%)...

This paper aims to 137 cases of breast malignant tumors confirmed by surgery and pathology were collected. All patients received ultrasound examination and were not treated by radiotherapy or chemotherapy before operation. The preoperative ultrasound images of breast cancer patients and postoperative pathological characteristics of paraffin sections were retrospectively observed. Ultrasound indicators included tumor size, shape, ratio of the longest/shortest dimension, edge of the spiculation and peripheral hyperechoic halo sign, internal echo types, micro calcification, posterior echo types, blood flow and signs of lymph node metastasis...
