In this study, we show that proliferation of breast cancer cells is suppressed by IGF-1-activated JNK MAPK pathway. The molecular mechanism by which c-jun-NH,-kinase (JNK) activation induces antiproliferative signals in IGF-1-stimulated breast cancer cells remains unknown. Tyrosine phosphatase SHP1 is known to negatively regulate signal transduction pathways activated by cell surface receptors ...

Brain metastases originate most commonly from carcinonoma of lung, breast, and colon and from melanoma. Therefore, metastatic adenocarcinoma to the brain are common metastatic brain tumor. Generally, metastatic adenocarcinoma in the brain appears low density on the non-enhanced computed tomography(CT). However, in very rare case mucin-containing metastatic adenocarcinoma show high density mimic...

Breast metastasis from extra-mammary malignancy is not common. According to the literature, an incidence of 0.4-1.3% has been reported. We present three cases of metastasis to the breast from two pulmonary adenocarcinoma and one lung squamous carcinoma diagnosed concomitantly or metachronous with the primary tumor. Two pulmonary adenocarcinomas (a 43-year-old female and a 45-year old female) pr...

The diagnosis of malignant mesothelioma in serosal effusions continues to be a major challenge because some of its cytomorphological features closely resemble adenocarcinomas. Immunohistochemistry is a valuable tool in the differentiation of epithelioid mesothelioma from metastatic adenocarcinomas. However, no single antibody has demonstrated absolute sensitivity or specificity. In this study, ...

Primary rectal adenocarcinoma metastatic to the breast is an exceedingly rare event. Its management differs from that of primary breast cancer, as illustrated by this case. A 63-year-old woman presented with a breast lump 30 months after abdominoperineal resection for rectal adenocarcinoma, stage T₃N₁M₀ (stage III), followed by standard postoperative radiochemotherapy. The patient underwent a m...

Metastasis to breast from nonmammary malignancy is only about 1.3-2.7%. A few cases of squamous cell carcinoma of esophagus and adenocarcinoma of stomach metastasizing to breast have been reported, but this is probably the first report of breast metastasis from esophagogastric junction (EGJ) cancer in the English literature. Herein we report a case of a 32-year-old patient diagnosed as adenocar...

OBJECTIVE We describe the case of a patient with metastatic breast cancer who presented with eyelid margin thickening and madarosis more suggestive of sebaceous cell carcinoma than metastatic disease. Histopathology confirmed metastatic breast adenocarcinoma. CASE REPORT A 59-year-old woman with a known history of metastatic breast carcinoma actively enrolled in a clinical trial presented wit...

BACKGROUND To determine in a large series of surgical biopsies, the frequency of various histologic types of primary solid malignant neoplasms in males and females in different age groups. METHODS A retrospective study of 20,000 consecutive surgical biopsies reposted in the section of histopathology, AKU in 2004. RESULTS Malignant neoplasms are commonest in the fifth and sixth decades of li...

Breast metastasis from gastric carcinoma is rare. We present a case of right breast mass with microcalcification in which the diagnosis of poorly differentiated adenocarcinoma from the stomach was made after a biopsy. Pleomorphic microcalcification was noted in the ill-defined breast mass, which is a rare feature in breast metastasis. Since breast metastasis usually signifies advanced metastati...
