Background: Breast cancer is not only considered as the most common cancer in women but also is known as the second cause of death among them. One of the main causes of death in breast cancer patients is metastasis to different organs such as lymph nodes, bones, lung, liver, brain or other parts of the body. Metastasis to genital organs especially uterus is rare and a few cases are reported. C...
Histological grading is a good parameter to stratify tumors according to their biological aggressiveness. The Elston and Ellis grading method in humans, invasive ductal breast carcinomas and other invasive tumors are routinely used. The aims of this study were classification of mammary gland tumors and also application of a human grading method in canine mammary carcinoma. The samples included ...
Background and Aim: Breast carcinoma is a pervasive malignancy in the world, and in our country-Iran-as well. Extensive studies have been done on its diagnostic and therapeutic procedures and factors affecting its prognosis. The present study aimed at determining proliferative rate of cells, the condition of steroid hormone receptors, correlation of these with each other and with other factors ...

Background & Aims: This study was performed to investigate possible relationships between the manifestation of stromal cells (fibroblasts and/or myofibroblasts) by focusing on expression of their matrix metalloproteinase 9 (MMP9) and possible angiogenesis based on CD31 and CD34 antigen expression during the various steps of hyperplastic changes to precancerousstate and invasive breast cancer. M...
Mucinous carcinoma is a type of ductal carcinoma with a low malignant potential. These tumors account for 2% of the breast carcinomas. These neoplasms are characterized by tumor cells floating in the pools of mucin. The prognosis of pure mucinous carcinoma is favourable when compared to the invasive ductal carcinoma, not otherwise specified. We report a case of 80years female patient presenting...
OBJECTIVE Apocrine carcinoma, a subtype of invasive ductal carcinoma of the breast, expresses androgen receptor (AR), but often lacks estrogen receptor (ER) and progesterone receptor (PgR). In the present study, the author immunohistochemically defined apocrine-type carcinoma as ER-/PgR-/AR+ invasive ductal carcinoma and analyzed the significance of apocrine-type carcinoma as triple-negative br...
INTRODUCTION Intracystic papillary carcinoma represents a small distinctive subgroup of noninvasive breast cancer, accounts for <0.5% of breast malignancies and is extremely rare in men, it was originally reported as a localized non-invasive carcinoma, but is usually associated with ductal carcinoma in situ around the main tumor or invasive carcinoma. CASE PRESENTATION We report a case of 50-...
Breast cancer is a heterogeneous disease composed of multiple subtypes. Infiltrating ductal carcinoma (not otherwise specified-NOS) is the most common type. This study was designed to detect HER -2 expression by immunohistochemistry on routine sections of breast carcinoma cases and to compare it with the histological grading of ductal carcinoma.
Mucinous carcinoma of the breast is a well differentiated, rare histological type of invasive ductal carcinoma, seen in oldest median age (69 years). We describe a case of a 60 yr old female with large right breast mass of 10 years duration with no nodal involvement. The reasons to present this case are 1) Because of its rarity. 2) Despite having a large tumour size, the axillary lymph node ...
