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 ...

mammary sarcomas are a heterogeneous group of malignant neoplasms that arise from the mammary stroma. primary sarcomas of the breast are extremely rare and comprise less than 0.1% of all malignant tumors of the breast. we present the case of a 56-year-old female diagnosed as stromal sarcoma, not otherwise specified - a very rare entity.

objective: n-nitroso-n-methylurea (nmu) induces breast cancer in rodents, particularly in rats. this model of breast cancer is very similar to human breast cancer. as a continuation of our recent work, we investigated the expressions of cyclin d1 and p21 in nmu-induced breast cancer of wistar albino rats. materials and methods: in this experimental study, mammary carcinoma was induced in female...

BACKGROUND:Canine mammary gland cancers are the most prevalent malignancies in dogs. There are different challenges regarding management of these cancers in dogs and human, one hypothesis is related to small cellular subset of tumor mass called cancer stem cell. These cells are therapy resistant and cause metastasis and relapse even after primary successful treatment. The well-identified phenot...

Despite a lot of research, the etiology and progression of breast cancer remain incompletely understood. Recently, human cytomegalovirus (HCMV) was reported as a risk factor for breast cancer. The aim of this study was to know whether breast cancer could be caused by cytomegalovirus or not? In this experiment seventeen samples of RAZI/A mice with spontaneous breast cancer were being gathered fr...

Background: Diagnostic molecular marker studies are in vogue to have insight of most prevalent animal diseases including cancer.Objectives: Gene expression profi ling of pro and anti-apoptotic genes was conducted in dog Lymphoma, CTVT, SCC, granuloma, perianal adenocarcinoma and mammary tumors.Materials and Methods: Cancerous tissue...

  Although most breast cancers are adenocarcinomas of the mammary gland, primary breast sarcomas may also arise from mammary gland mesenchymal tissue. Sarcomas represent less than 1% of primary breast neoplasms. These tumors are at high risk of recurrence and are known to have poor prognosis. Surgical resection is the primary treatment for these lesions and axillary lymph node dissection is no...
