Background and Objectives: Breast cancer is the most common malignancy among women in the world. The aim of this study was to assess estrogen receptor (ER), progesterone receptor (PR) and HER-2/neu of infiltrating ductal carcinoma (IDC) with tumor size, histologic grade, lymph node metastasis and age. Methods: This study was carried out on 300 tissue blocks ofpatients with ID...
BACKGROUND Invasive urothelial carcinoma, lymphoma-like/plasmacytoid variant, is a rare histological type of bladder cancer similar to plasma cells and is an aggressive variant of urothelial carcinoma associated with a poor prognosis. CASE PRESENTATION A 41-year-old Asian man was referred to our hospital due to macroscopic hematuria. Cystoscopy detected a non-papillary tumor, and a transureth...
Pleomorphic lobular carcinoma of the breast has been identified as a histological variant of infiltrating lobular carcinoma (ILC) with poor prognosis. Thus, cytological recognition of this tumour is important. It is characterized by pleomorphism to a degree that contrasts with the cytologic uniformity of classic ILC. Due to this feature it is often misinterpreted as infiltrating ductal carcinom...
The caecum and the ascending colon are the colon segments most frequently affected by tumoral synchronism. Synchronous colorectal carcinoma etiopathogenesis is complex and most likely by malignancy of preexisting adenomas (adenoma-adenocarcinoma sequence). The following tumoral synchronism clinical case's particularity is represented by the simultaneous diagnosis of a flat-type adenocarcinoma o...
Introduction. Tattoos have increasingly become accepted by mainstream Western society. As a result, the incidence of tattoo-associated dermatoses is on the rise. The presence of a poorly differentiated squamous cell carcinoma in an old tattooed skin is of interest as it has not been previously documented. Case Presentation. A 79-year-old white homeless man of European descent presented to the d...
UNLABELLED Primary mesenchymal chondrosarcoma of the kidney is rare, and it shows distinct undifferentiated tumor cells and well differentiated cartilagenous components. Also assident infiltrating urothelial carcinoma of the ureter is an extremely rare cancer. We report a case of primary mesenchymal chondrosarcoma occurring in the left kidney with an ipsilateral and distinct distal ureteric imp...
Introduction The aim of this study was to evaluate the expression of PD-L1 in oropharyngeal squamous cell carcinoma. Its relation with clinicopathological variables, tumor infiltrating lymphocytes and survival was also determined. Results Positive PD-L1 status for the SP142 clone related with improved overall survival in oropharyngeal squamous cell carcinoma. Tumors heavily infiltrated by tum...
In females, the most common cancer is breast carcinoma in which squamous cell carcinoma (SCC) is a rare type of malignancy. Histologically, infiltrating ductal carcinoma is the most common type and lobular, mucinous, and medullary types have lower incidence. Pure SCC of the breast can originate from the skin, nipple, or epithelium of a deep-seated dermoid cyst or squamous metaplasia on chronic ...
