Carcinoma male breast with tracheal and endobronchial metastasis, masquerading as nonsmall-cell lung cancer, presenting with superior vena cava obstruction - A rare case report.

Cancer male breast is not very common. It comprises <1% of all breast cancers. Primary sites of metastasis are bone, brain, lung, and liver.

Oxidative stress responses of a freshwater fish, Labeo rohita, to a xenobiotic, bisphenol S.

Bisphenol S (BPS) is an organic chemical that has been used as a substitute for bisphenol A (BPA) in making polycarbonate plastics, epoxy resins, thermal receipt papers, and currency bills, as BPA has been reported to have dreadful effects on the living system. From this view point, the present study investigates whether BPS has the same or rather more toxic effects like BPA or not. Limited studies were carried out on the effect of BPS on fish.

Hemophagocytic Lymphohistiocytosis Complicating Methotrexate Toxicity.

Hemophagocytic syndrome or hemophagocytic lymphohistiocytosis (HLH) is a rare but potentially fatal disease caused by dysregulated activation of macrophages against one's blood cells. Major pathologic feature of HLH is hemophagocytosis. We present a case of HLH complicating methotrexate toxicity in a 65-year-old psoriatic patient with history of renal disease.

Sequential EGFR mutation and ALK rearrangement in adenocarcinoma lung, with rare metastasis to bilateral breast, ovary and endometrium.

With the advent of targeted therapies there was a paradigm shift in the treatment of metastatic adenocarcinoma of lung. Immuno-histopathology and molecular subtyping in metastatic adenocarcinoma lung have enabled personalized treatment for each patient. Oncogenic driver mutations in non-small cell lung cancer are commonly EGFR (Epidermal Growth Factor Receptor) gene mutation and ALK (Anaplastic Lymphoma Kinase) gene rearrangement, which are mutually exclusive.
