Purpose: Complete lymph node dissection is the recommended treatment for clinically detectable lymph nodes in stage III melanoma. This surgery is associated with substantial morbidity. We hypothesize that combining percutaneous imaging-guided cryoablation of locoregional lymph nodes metastases with neoadjuvant in situ and systemic immunotherapy could allow disease control and evaluate the feasibility of this combination in this proof-of-concept study.
Methods: We enrolled 15 patients with stage IIIB/IIIC melanoma. Patients were treated as follows: a single 240 mg flat dose infusion of nivolumab on day 1, cryoablation under local anesthesia using CT on day 2, and a single intralesional injection of 10-20 mg of ipilimumab into the lymphadenopathy treated by cryotherapy on day 3. Five-eight weeks after this procedure, complete lymph node dissection was performed according to routine care. The primary outcome measure of this study was feasibility, measured as the number of failures (i.e., inability to complete the entire procedure).
Results: The procedure was carried out successfully in 15 out of 15 patients with an observed number of failures of 0. The Bayesian analysis showed an estimated failure rate of 4.2% [0.2-20.6]. Eight patients (53%) had adverse events secondary to either immunotherapy or cryotherapy. Grade 3/4 events occurred in three patients, but all resolved quickly and patients could proceed to surgery as scheduled. Eight patients (53%) had a pathological complete or near complete response.
Conclusion: Combining percutaneous cryotherapy with in situ ipilimumab and systemic nivolumab for stage III resectable melanoma is feasible with tolerable toxicity.

Background: Metastases in the lateral pelvic lymph nodes or mesenteric lymph nodes represent distinct categories of mid-low rectal cancer. This study investigated the patterns of mesenteric and lateral pelvic lymph node metastases in mid-low rectal cancer; the survival benefit of postoperative treatment was also analysed in these groups.
Methods: This retrospective multicentre study included consecutive patients with mid-low rectal cancer who underwent total mesorectal excision with lateral pelvic lymph node dissection in three Chinese institutions between 2012 and 2020.

The regulation of follicular (F) and germinal center (GC) immune reactivity in human lymph nodes (LNs), particularly during the acute stages of viral infection, remains poorly understood: We have analyzed lung-draining lymph nodes (LD-LNs) from COVID-19 autopsies using multiplex imaging and spatial transcriptomics to examine the immune landscape with respect to follicular immune reactivity. We identified three groups of donors based on the Bcl6 prevalence of their Reactive Follicles (RFs): RF-Bcl6no/low, RF-Bcl6int, and RF-Bcl6high. A distinct B/TFH immune landscape, associated with increased prevalence of proliferating B-cell and TFH-cell subsets, was found in RF-Bcl6high LD-LNs.

Rosai-Dorfman disease (RDD) is a rare histiocytic disorder that may clinically and histologically resemble IgG4-related disease (IgG4-RD), especially in the presence of IgG4-positive plasma cell infiltration. In this case, a 69-year-old woman with generalized lymphadenopathy, constitutional symptoms, and elevated IgG4 levels was initially suspected to have IgG4-RD based on core needle biopsy. However, further evaluation with excisional lymph node biopsy revealed emperipolesis and S100-positive histiocytes, confirming the diagnosis of RDD.

Enteroinvasive bacterial pathogens are responsible for an enormous worldwide disease burden that critically affects the young and immunocompromised. is a gram-negative enteric pathogen closely related to the plague agent that colonizes intestinal tissues, induces the formation of pyogranulomas along the intestinal tract, and disseminates to systemic organs following oral infection of experimental rodents. Prior studies proposed that systemic tissues were colonized by a pool of intestinal replicating bacteria distinct from populations within Peyer's patches and mesenteric lymph nodes.

Background: Mantle cell lymphoma (MCL) is a subtype of non-Hodgkin lymphoma characterized by the proliferation of B-cells. Severe hyperleukocytosis is an uncommon presentation that can complicate the diagnosis and management of MCL.
Methods: We present the case of an 80-year-old male patient suffering from MCL, who exhibited symptoms including severe hyperleukocytosis, lymphadenopathy, and significant bone marrow infiltration.
