[Intravascular Large B-cell Lymphoma Presenting with Lung Adenocarcinoma: A Case Report and Literature Review]

Intravascular large B-cell lymphoma (IVLBCL) is an aggressive extranodal large B-cell lymphoma, cocurrence in the same organ with other malignancies is very rare, especially in the lung. Here, we report a rare case of lung adenocarcinoma with IVLBCL. The patient was admitted to the hospital due to diarrhea associated with fever and cough. A computed tomography (CT) scan of the chest showed an irregular patchy high-density shadow in the upper lobe of the right lung with ground-glass opacity at the margin. After admission, the patient was given anti-infection treatment, but still had intermittent low fever (up to 37.5 °C). The pathological diagnosis of percutaneous lung biopsy (PLB) was lepidic-predominant adenocarcinoma with local infiltration, which was proved to be invasive nonmucinous adenocarcinoma of the lung with IVLBCL after surgery. This paper analyzed the clinicopathological characteristics and reviewed the relevant literature to improve the knowledge of clinicians and pathologists and avoid missed diagnosis or misdiagnosis.

Prediction of carcass weight from body measurement traits of Chinese indigenous Dagu male chickens using path coefficient analysis

In the current study, correlation and path coefficient analysis were applied to investigate the relationship among body measurement traits and carcass weight, and to determine the direct and indirect effects of the body measurement traits including body slope length (BSL), breast width (BW), breast depth (BD), pelvis width (PW), shank length (SL) and shank circumference (SC) on carcass weight. Chinese indigenous Dagu male chickens (80) were used at eighteen weeks of age. Pair-wise correlation results showed high significance between carcass weight and body measurement traits. High correlation was between carcass weight and body slope length (0.596) while the lower correlation was between breast depth and shank length (0.112), respectively. Path coefficient analysis results indicated that shank circumference and shank length had the highest direct effect (0.225, 0.223) on carcass weight than other body measurement traits and breast depth had the highest indirect effect (0.125), respectively.The current study might be used by chicken farmers for prediction of carcass weight while the chicken is still alive.
