Point mutations in the KIT receptor tyrosine kinase gene have recently been identified in mucosal, acral lentiginous, and chronically sun-damaged melanomas. We have identified the first human melanoma cell line with an endogenous L576P mutation, the most common KIT mutation in melanoma ( approximately 30-40%). In vitro testing showed that the cell viability of the L576P mutant cell line was not...

Pleomorphic carcinoma is a rare and very aggressive subtype of lung cancer that tends to grow rapidly and invade adjacent structures. Here we report a case of pleomorphic carcinoma with rapid growth, multiple metastases, and intestinal perforation. A 46-year-old man was admitted to our hospital because of lung abscess. Several antibiotics were administered for 2 weeks, but his condition did not...

Carcinoma of unknown primary (CUP) is where the primary site remains unidentified even though metastases are present, and accounts for 3-5% of all human malignancies. Here, we report a multidisciplinary approach to the treatment of a squamous cell CUP occurring in the left cervical region. Following radical surgery for carcinoma of the colon, swelling occurred in the left cervical region in a 5...

BACKGROUND The outcome of patients with severe ischaemic left ventricular (LV) dysfunction is determined by the extent of myocardial viability and the presence of LV dyssynchrony. We aimed at assessing both parameters from the same imaging method, i.e. gated positron emission tomography (PET) F18-fluorodeoxyglucose (FDG) scans. METHODS Phase analysis from Emory Cardiac Toolbox was applied on ...

RATIONALE AND OBJECTIVES F18-fluorodeoxyglucose (FDG)-positron emission tomography (PET) studies have clinical value in suspected recurrent or metastatic colorectal cancer cases. Because this modality is not accessible for many patients, a camera-based FDG (CB-FDG) coincidence imaging was suggested as an alternative. Although inferior in resolution to a dedicated PET system, it can make FDG stu...

18F-Fluorodeoxyglucose-positron emission tomography/computed tomography is a noninvasive imaging modality that appears to have a high negative-predictive value for malignancy in assessing solid splenic masses discovered on conventional imaging modalities. Histological sampling is recommended for fluorodeoxyglucose-avid splenic masses, as the main differential diagnosis includes malignancy, eith...

We present a case of a 60-year-old woman with history of follicular lymphoma in remission presenting for an 18F-fluorodeoxyglucose positron emission tomography/computed tomography for suspected recurrence. Imaging showed widespread hypermetabolic lymphadenopathy consistent with lymphoma recurrence. A 3-month 18F-fluorodeoxyglucose positron emission tomography/computed tomography follow-up after...

It has been reported that F18-fluorodeoxyglucose (FDG) uptake in the neck and supraclavicular lesions represents activated brown adipose tissue (BAT). In the present study, the association between BAT activity, detected by FDG-positron emission tomography (PET), and the clinicopathological features of patients with breast cancer was investigated. The cases of 156 consecutive patients with breas...
