Vandetanib is a once-daily oral anticancer drug that selectively inhibits key signaling pathways in cancer by targeting vascular endothelial growth factor receptors, epidermal growth factor receptors tyrosine kinase, and rearranged during transfection-dependent tumor cell proliferation and survival. The most frequently reported adverse events attributed to(More)
BACKGROUND Melanogenesis is one of the characteristic parameters of differentiation in melanocytes and melanoma cells. Specific inhibitors of phosphatidylinositol 3-kinase (PI3K), such as wortmannin and LY294002, stimulate melanin production in mouse and in human melanoma cells, suggesting that PI3K and mammalian target of rapamycin (mTOR) might be involved(More)
Malignant acanthosis nigricans is a cutaneous eruption characterized by symmetric hyperpigmented hyperkeratosis, dermal papillomatosis, and mucosal involvement associated with internal malignancies. Tripe palms refers to a characteristic velvety thickening of the palms, with exaggeration of normal skin markings. We present the second case of ovarian cancer(More)
Epidermal growth factor receptor (EGFR) is a member of the receptor tyrosine kinase (RTK) family. Epidermal growth factor induces its dimerization and stimulates phosphorylation of intracellular tyrosine residues. Phosphorylation of EGFR is studied for cancer therapy because EGFR regulates many cellular processes including cell proliferation,(More)
Undifferentiated pleomorphic sarcoma, known as malignant fibrous histiocytoma, is a malignant neoplasm that arises in both soft tissue and bones. In 2002, the World Health Organization declassified malignant fibrous histocytoma as a formal diagnostic entity and renamed it 'undifferentiated pleomorphic sarcoma not otherwise specified.' It most commonly(More)
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Dear sir: A 40-year old woman was referred for consultation for skin eruption on her entire body of two month duration. Four years ago, her diagnostic cystoscopic examination revealed transitional cell carcinoma of the(More)
Parkinson’s disease (PD) is a progressive degenerative disorder of the central nervous system. Levodopa (L-dopa), dopamine precursor is the most effective therapeutic drug for PD patients. Levodopa (LDP) and its three metabolites in rat plasma were determined using high performance liquid chromatography coupled with tandem mass spectrometry (LC–MS/MS).(More)
We report on a rare case of fluconazole induced fixed drug eruption in a 62-year old female patient. She was referred to our department for multiple erythematous itchy maculopatches on the face, neck, both upper arms, and trunk area, which had occurred over the previous 6 months. Her attending physician prescribed fluconazole for treatment of onychomycosis.(More)
