Dendritic cells, macrophages and B cells are regarded as the classical antigen-presenting cells of the immune system. However, in recent years, there has been a rapid increase in the number of cell types that are suggested to present antigens on MHC class II molecules to CD4+T cells. In t...
Atypical mitoses are present in otherwise classical pleomorphic lipomasObjective: Programmed death ligand 1 (PD-L1) found on tumor cells has recently been reported to have a key role in the development and dissemination of many tumors, such as lung and breast carcinomas. In this study, we ...
The patient was screened for sexually transmitted infections, and he tested positive for HIV (viral load of 100,000 copies/ ml, CD4 count of 190 cells/mm3) and syphilis [rapid plasma regain (RPR) titer: 1:512]. The chest x-ray was unremarkable. He started antiretroviral therapy (bict- ...
The purpose of the present study was to compare histology outcomes of cytological atypical squamous cells of undetermined significance (ASCUS) to the histo... ADCT Karol,MFCT And,JA Maksem - 《Diagnostic Cytopathology》 被引量: 81发表: 1999年 Colposcopic evaluation after a repeat atypical squamous...
We hypothesize that the neoplastic cells may locally produce high levels of androgens or androgen-like bioactivity molecules that are responsible for the clinical manifestation. We suggest that a testicular ultrasound should be obtained in all children presenting with unilateral pubarche, with or without...
A perilymphatic pattern of nodules is present, although this appearance is somewhatatypical. 虽然不是十分典型, 但仍是淋巴管周围型结节. 期刊摘选 Presence ofatypicalglandular cells on Papanicolaou smear. 涂片发现有非典型腺细胞者. 期刊摘选 To raise the recognition ofatypicalpulmonary manifestations caused...
We present our experience of fine-needle aspiration (FNA) cytology of the thyroid in a community hospital setting and discuss the cancer probability of the... HJ Wu,JN Jones,J Osman - 《Diagnostic Cytopathology》 被引量: 152发表: 2010年 Atypical Epithelial Cells, Cannot Exclude Papillary Carcin...
We present an ultrastructural depiction of erythrocytes, platelets, and the fibrin network, to explain the clinical manifestations of the thrombotic state seen in this patient. 展开 关键词: Iron overload platelets pro-thrombin mutation red blood cells ...
These atypical cells were similar in shape to those present in the blood of patients with IM induced by Epstein-Barr virus (EBV). Via Unscheduled DNA Synthesis (UDS), DNA synthesis was demonstrated in the atypical cells whose phenotype is identical to that of B cells, as shown with a ...
However, Epstein–Barr virus-encoded small RNA-positive cells were not identified by in situ hybridization. The polytypic nature of B lymphocytes also was demonstrated by immunohistochemistry and polymerase chain reaction. Moreover, there was no history of MTX therapy in the present case, indicating ...
