Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are used as a treatment for non-small cell lung cancer. There have been some reports of EGFR-TKIs being associated with vascular adverse events. We found that EGFR-TKIs decreased the proliferation of HMEC-1 (immortalized human
UNASSIGNED
Purpuric skin lesions have only rarely been reported in patients receiving epidermal growth factor receptor inhibitors. However, their clinical and histopathologic presentations have varied considerably.
UNASSIGNED
To characterize purpuric skin eruptions caused by epidermal growth factor
BACKGROUND
STI571, a selective BCR-ABL tyrosine kinase inhibitor, is a promising new drug for chronic myelogenous leukemia (CML). However, the drug has been reported to be associated with adverse cutaneous drug eruptions with high frequency.
OBJECTIVE
In this study, the characteristics of the
Imatinib mesylate, the first agent approved for the treatment of unresectable or metastatic gastrointestinal stromal tumor, is a tyrosine kinase inhibitor targeting (KIT) and the platelet-derived growth factor receptor-α and -β. However, imatinib administration can be accompanied by various adverse
Imatinib mesylate (imatinib) is a tyrosine kinase inhibitor initially approved by the US Food and Drug Administration in 2001 for chronic myeloid leukemia (CML). Since then, the number of indicated uses for imatinib has substantially increased. It is increasingly important that dermatologists
Sunitinib is an oral multi-targeted tyrosine kinase inhibitor. It has been approved for the treatment of gastro-intestinal stromal tumor and advanced renal cell carcinoma. Fixed drug eruption related to sunitinib is a rare cutaneous adverse drug reaction.
Sorafenib, an epidermal growth factor receptor inhibitor, is a novel treatment used for malignancies resistant to traditional chemotherapy. Epidermal growth factor receptors (EGFR) are a family of 4 transmembrane tyrosine kinase receptors that, via signal transduction pathways, mediate cell growth,
Cutaneous adverse events are commonly experienced with use of tyrosine kinase inhibitors in the treatment of leukemia and typically include nonspecific cutaneous eruptions and xerosis. We report the case of a man who experienced an ichthyosiform drug eruption while taking ponatinib, a
Vandetanib is an inhibitor of the vascular endothelial growth factor receptor 2 tyrosine kinase and the epidermal growth factor receptor tyrosine kinase, recently used in the treatment of different tumors. We describe a case of a photo-allergic reaction to vandetanib in an 80-year-old Caucasian
We herein report a case of diffuse alopecia with pustules on the scalp and purpuric lesions on the lower legs in a Japanese man after treatment with erlotinib. This is a unique case in which rare skin eruptions simultaneously occurred. We discuss herein a combination of skin eruptions as an adverse
Vandetanib is a tyrosine kinase inhibitor approved by the United States Food and Drug Administration for the treatment of metastatic medullary thyroid cancer. It has been linked to a variety of dermatologic reactions, including photosensitivity. We describe the case of a 55-year-old man who
The prognosis of metastatic or recurrent GISTs is poor, because these tumors resist chemotherapy and radiotherapy. We report a patient with recurrent GIST who underwent molecularly targeted therapy with imatinib, a novel oral tyrosine kinase inhibitor. A 64-year-old man presented with large
BACKGROUND
Gleevec trade mark is a protein tyrosine kinase inhibitor used in the treatment of chronic myelogenous leukemia and gastrointestinal stromal tumor. Currently, Gleevec is also being used in protocols for treatment of other malignancies such as melanoma. A few, non-descript cutaneous
OBJECTIVE
Acute graft-vs-host disease (GVHD) typically requires high-dose systemic steroids as first-line treatment. Like drug eruptions, viral exanthema, and toxic erythema of chemotherapy, Demodex folliculitis is a clinical mimicker of acute GVHD and requires nonimmunosuppressive therapy. This
Crizotinib is an oral small-molecule anaplastic lymphoma kinase (ALK) tyrosine-kinase inhibitor for the treatment of ALK-positive non-small-cell lung cancer (NSCLC). A 63-year old woman with postoperative relapsed ALK-positive NSCLC was treated with crizotinib. Erythema multiforme (EM) occurred one
