BACKGROUND Several randomized phase III studies in advanced stage non-small cell lung cancer (NSCLC) confirmed the superior response rate and progression-free survival of using epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor as first-line therapy compared with chemotherapy in patients with activating EGFR mutations. Despite the need for(More)
We describe large B cells, many of which have a stellate or dendritic morphology, found in the interfollicular T-cell-rich areas of human peripheral lymphoid tissue. These B cells probably require CD40/CD40 ligand signaling for their generation and have a unique phenotype and a post-germinal center pattern of immunoglobulin gene mutation. The only(More)
Trisomy 12, t(14;18)(q32;q21), and t(8;14)(q24.1;q11.2) were found in a 59-year-old man with B-cell chronic lymphocytic leukemia (CLL). While trisomy 12 is one of the most common cytogenetic abnormalities in chronic lymphocytic leukemia, the t(14;18) rearrangement has a strong association with follicular lymphoma and the t(8;14) is associated with T-cell(More)
A man presented with shortness of breath, and a globular heart was seen on a chest radiograph. An echocardiogram showed masses at the atrioventricular grooves. Computed tomography (CT) coronary angiography and fluorine-18 ((18)F) fluorodeoxyglucose positron emission tomography (FDG-PET)/CT confirmed coronary aneurysms with hypermetabolic perivascular masses(More)
BACKGROUND Bcl-x appears to have an antiapoptotic role in the epidermis. Little is known about the expression of Bcl-x in cutaneous adnexal structures and benign cutaneous adnexal tumors. METHODS Tissues from 31 cases of benign cutaneous adnexal tumors (five trichofolliculomas, five trichoepitheliomas, two sebaceous adenomas, five apocrine hidradenomas,(More)
Cutaneous biopsies are traditionally studied for the expression of cellular markers by immunoenzymatic techniques. However, immunofluorescent analysis is a valuable, and largely overlooked, ancillary technique that can resolve questions arising from conventional immunostaining, since it allows pairs of antigens to be simultaneously visualized. Furthermore,(More)
PURPOSE 32P BioSilicon is a new, implantable, radiological medical device that comprises particles of highly pure silicon encapsulating 32phosphorus (32P) for the treatment of unresectable solid tumors. Prior to administration, the device particles are suspended in a formulant which provides an even suspension of the intended dose for implantation. The(More)
Epidemiologic studies have reported an inverse association between sun exposure and non-Hodgkin lymphoma (NHL), but these have been almost exclusively conducted in Western populations residing in temperate locations. We evaluated the association between personal outdoor sun exposure and risk of malignant lymphomas in Singapore. A hospital-based case–control(More)
Primary cutaneous, extranodal natural killer/T-cell lymphoma, nasal type (PC-ENKTL), is a rare Epstein-Barr virus (EBV)-associated neoplasm with poorly defined clinicopathologic features. We performed a multinational retrospective study of PC-ENKTL and CD56-positive EBV-negative peripheral T-cell lymphoma (PC-CD56+PTCL) in Asia in an attempt to elucidate(More)
