Distribution of breast cancer subtypes among Jordanian women and correlation with histopathological grade: molecular subclassification study.

Objective: To evaluate the hormone receptor status and human epidermal growth factor receptor 2 (HER2)/neu gene expression among Jordanian women with breast cancer. To classify our patients into molecular subtypes and to correlate the results with age of the patients and tumour grade.

Design: Evaluation of estrogen receptor (ER), PR and HER2/neu was done by standard immunohistochemical technique and subclassification into molecular subtypes.

Carcinoma of breast co-existing with non-Hodgkin's lymphoma of axillary lymph nodes.

The co-existence of breast carcinoma and lymphoma in the axillary lymph nodes, without a history of previous chemotherapy or radiotherapy is rarely described. We present a case of a 50-year-old female with right breast mass, proved by pathological examination to be invasive mucinous carcinoma. Examination of the axillary lymph nodes as axillary clearance showed concomitant small lymphocytic lymphoma and chronic lymphocytic leukemia, with no evidence of metastatic mammary carcinoma deposits.
