Salivary gland tumors, the second most common neoplasm of the mouth after squamous cell carcinoma, account for a significant proportion of tumors of the oral and perioral regions. An unusual case of adenoma presented as a solitary intraoral palatine mass in a 32-year-old woman is reported here. The tumor was interpreted as an unusual pleomorphic adenoma because of the presence of exuberant squa...

Pleomorphic carcinoma of the breast is a rare variant of invasive breast carcinoma. Here, we report a case in a 45-year-old woman presenting a lesion composed microscopically of predominantly pleomorphic giant cells, squamous metaplastic component and focal conventional ductal carcinoma. Immunohistochemical assay showed different immunologic manifestation in respective malignant components. Des...

A group of 26 examples of lung carcinoma showing mixed squamous and glandular differentiation is described. The clinical and biological features of the lesions are intermediate between those of squamous-cell carcinoma and adenocarcinoma of the bronchus. It is suggested that bronchial carcinoma is a single entity in which the type of oell, whether glandular or squamous, plays a much smaller part...

Introduction: Breast cancer is one of the most common malignant tumors and leading causes related death amongst females worldwide. The clinical significance molecular classification carcinoma breast remains to be established. Molecular subtyping using immunohistochemistry can provide additional prognostic predictive information. Aim objectives: To identify morphological variants determine vario...

BACKGROUND Metaplastic breast carcinoma is a rare entity of breast cancer expressing epithelial and/or mesenchymal tissue within the same tumor. The aim of this study is to evaluate the clinicopathological features of metaplastic breast carcinoma and to confirm the triple negative, basal-like and/or luminal phenotype of this type of tumor by using immunohistochemical staining. METHODS Seven c...

Introduction: Apocrine carcinoma (AC) is an uncommon variant of breast carcinoma. The incidence of apocrine carcinoma is approximately 4% of mammary carcinomas. Case Series: In this study five cases of apocrine breast carcinoma were identified. Three cases of apocrine breast carcinoma with infiltrating (IF) AC and two cases with intraductal (ID) AC. The cytologic featuers showed large malignant...

Interpretation of F-FDG PET/CT studies in breast is challenging owing to nonspecific FDG uptake in various benign and malignant conditions. Benign conditions include breast changes in pregnancy and lactation, gynecomastia, mastitis, fat necrosis, fibroadenoma, intraductal papilloma, and atypical ductal hyperplasia. Among malignancies, invasive ductal carcinoma and invasive lobular carcinoma are...
