Bronchus-associated lymphoid tissue lymphoma is a rare disease. It is the most common form of primary pulmonary lymphoma but accounts for less than 1% of all non-Hodgkin's lymphomas. We describe a 67-year-old man who, despite successful treatment of active miliary tuberculosis, developed progression of a concomitant bronchus-associated lymphoid tissue lymphoma. This case is in contrast to previous reports of gastrointestinal-mucosa-associated lymphoid tissue lymphomas and bronchus-associated lymphoid tissue lymphomas, in which treatment of the precipitating antigenic stimulus lead to remission of the lymphoma.

Objectives: This study investigated the prognostic role of log odds of negative lymph node/T stage (LONT) and established a nomogram based on LONT to predict the prognosis in colorectal cancer (CRC) patients.
Design: A retrospective cohort study.
Setting And Participants: We enrolled 80 518 CRC patients from the Surveillance, Epidemiology and End Results database between 2010 and 2015.

Background: This study aims to evaluate the predictive usefulness of a habitat radiomics model based on ultrasound images for anticipating lateral neck lymph node metastasis (LLNM) in differentiated thyroid cancer (DTC), and for pinpointing high-risk habitat regions and significant radiomics traits.
Methods: A group of 214 patients diagnosed with differentiated thyroid carcinoma (DTC) between August 2021 and August 2023 were included, consisting of 107 patients with confirmed postoperative lateral lymph node metastasis (LLNM) and 107 patients without metastasis or lateral cervical lymph node involvement. An additional cohort of 43 patients was recruited to serve as an independent external testing group for this study.
Artificial intelligence performance in ultrasound-based lymph node diagnosis: a systematic review and meta-analysis.

Background And Objectives: Accurate classification of lymphadenopathy is essential for determining the pathological nature of lymph nodes (LNs), which plays a crucial role in treatment selection. The biopsy method is invasive and carries the risk of sampling failure, while the utilization of non-invasive approaches such as ultrasound can minimize the probability of iatrogenic injury and infection. With the advancement of artificial intelligence (AI) and machine learning, the diagnostic efficiency of LNs is further enhanced.

Lymphedema is a chronic condition caused by the accumulation of protein-rich fluid in the interstitial tissue, resulting in edema and a diminished quality of life. When first-line treatments like complete decongestive therapy (CDT) fail, surgical options are considered. These include physiological procedures like lymphaticovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT), which aim to restore lymphatic function, as well as reductive procedures such as liposuction and excisional techniques, which reduce limb volume.

With advanced mass spectrometry (MS)-based proteomics, genome-scale proteome coverage can be achieved from bulk tissues. However, such bulk measurement lacks spatial resolution and obscures tissue heterogeneity, precluding proteome mapping of tissue microenvironment. Here we report an integrated wet collection of single microscale tissue voxels and Surfactant-assisted One-Pot voxel processing method termed wcSOP for robust label-free single voxel proteomics.
